Metal plastic pipes for water installation. Metal plastic pipes

Metal-plastic pipes due to its advantages over metal products are widely used for mounting pipelines in apartments and private (s) houses. How is the gasket of metal-plastic pipes , and all their advantages and features are discussed in this article.

Design of metal-plastic products

Pipes made of metalplastic are products consisting of five layers:

Internal polyethylene layer.
Layer of special adhesive composition.
Intermediate carrier aluminum layer.
The second layer of special adhesive composition.
External polyethylene layer.

Since the cost of components that are part of the product is not high, then the cost of metal-plastic pipes and fitting products is also not large.

Advantages of metal plastic pipes

Metal-plastic products used for installation of the water pipeline differs favorably before alternatives. First of all, it is advisable to replace pipes into metal-plastic due to their positive properties:

large service life, which is at least 50 years later, subject to installation and operation of pipeline products in strict accordance with the technical standards;
resistance to corrosion;
the absence of the formation of salt and lime deposits on the inner surface of the pipes, which provides them with good bandwidth over a long period of operation;
the absence of toxic components of metalplastic;
the low weight of the products, due to which such pipes do not create loads on the foundation or overlap of the house;
supply of products of bays allows minimizing product waste during pipeline laying;
light laying of metal-plastic pipes without the use of welding and special tools;
a fairly high effect of noise absorption, so it is possible to lay a pipeline without insulating material;
lack of need for painting and other maintenance of products;
low heat transfer coefficient;
high mechanical strength (up to 10 atmospheres);
sufficient plasticity of products from metalplastic: If water freeze in the pipe, it will simply expand, but will not collapse;
good thermal resistance when transporting a hot work environment;
the ability to mount pipes into a concrete screed due to the minimum linear voltage.

Installation of pipeline from metalplastic

Easy work with products allows for saving funds to organize the installation of a pipeline in an apartment or a country house (dacha) on their own. Metal-plastic pipes are laid by their own order of the procedure below.

Preparatory work

Before laying pipes, ball trunk cranes are installed on hot or cold water riser. Next, after the cranes, water purification filters, counters, pressure reducer and a collector, which is responsible for the uniform distribution of water between sanitary devices are mounted. From the collector around the apartment or house to sanitary devices, metal-plastic pipe layout is performed . The positive point of the collector wiring is that the pipe is one thread without unnecessary branches and connections is connected to a specific sanitary factor.

Cutting pipe

Products are supplied by bays, so pieces of pipes of the required length are cut off. This operation should be carried out with the help of special cutting scissors (pipe cutters). When using another tool, there is a high probability of damage to the protective layer of the pipe. In addition, the criterion will not be even, which will further affect the sealing of the compound. In the most extreme case, you can use the metal hacksaw with very small leaf teeth.

After trimming, it is necessary to remove with the help of girlfriend, such as a round file or knife, the sharp edge of the pipe cutting, otherwise it can damage the rubber seals when tightening the connection.

Product connection

Connect pipes from metalplastic can be used:

crimping (compression) screw fittings;
press fittings.

Using crimp fittings, detachable connecting nodes are obtained. Sealing with a pipe at the same time is provided by a sealing split ring, which is tightened with a presser nut. Such a connection requires constant control and periodic suspenders.

For monolithic (unbearable) compounds, press fittings are applied, the installation of which is carried out using a special tool. Since metal-plastic pipe products are laid mainly by the hidden method in the wall, it is necessary to ensure reliable tightness of the compounds.

Consider how to install a reliable connecting unit by applying compression fittings:

First, a clamp nut, as well as a split sealing ring, is trained.
For sealing compounds on fittings, additional rubber sealing rings are mounted. To prevent their damage, the pipe must be deflated, applying a special calibrator.
Fitting fitting is inserted into the collapsed end of the pipe.
At the next stage, the fitting is assembly. Returns a split ring, and the connecting node is hermetically tightened with a nut.

The nut must be tightly tighten the corresponding key to the characteristic crackling, but with caution, without applying excessive effort. It is very important to pay attention and check the quality of the thread when buying fitting products. It should not contain any burstles.

Bending pipeline

If it is necessary to make bending during the pipeline laying, a special spring is used or a flexible inner (outer) mandrel that prevents the pipe to reduce the enlightenment or breakdown of the product during bending. The mandrel is selected with a dimension that corresponds to the diameter of the pipe.

The metal-plastic product is bent into small uniform movements until the desired configuration or bending angle is obtained. After the end of the spring procedure or mandrel is removed from the pipe.

Fastening

Fastening metal-plastic pipes to the plane paved can be ensured, if you apply special clips. They are produced different sizes for use with pipeline products of different diameters. These attachments provide axial movement of pipes when heated. To ensure the accuracy of the laying of the highway before installing the clip, it is advisable to carry out the appropriate markup.

You can use for mounting pipeline products and special supports or suspensions. In the case of the use of metal fastening, it is necessary to put gaskets from any soft material.

Rules of gasket highway

Metal-plastic products allow you to lay a pipeline in an apartment or nadaach both open and hidden way in the soil or wall.

When laying pipes, it should be remembered that for metal-plastic products it is necessary to eliminate sharp pressure drops. Therefore, the highway provides for the installation of special gearboxes, allowing to level pressure in the system.

Installation of metal-plastic pipes is performed in compliance with the following rules:

The manufacturer is recommended to maintain a pipeline using metal-plastic pipes at an ambient temperature of at least 10ºС.
If the pipes were transported (stored) at a minus temperature, they need to withstand some time to warm up before installation.
With the opening of the gasket, for example, in the bathroom, the installation of the pipeline is carried out after the end of the finishing wall (ceiling) works.
Fractures of pipeline products during installation are not allowed.
When laying pipes in an open way or in Earth, it is necessary to minimize the effect on them direct ultraviolet and strong mechanical impact.
With a hidden laying of products, it is necessary for the entire length of the highway to provide viewing hatches for organizing access to fitting compression compounds.
If necessary, pave a pipe through the wall or partition use mortgage sleeves by 10.0 mm exceeding the diameter of the product. Free space is filled with material that does not support combustion. In any case, the possibility of axial free movement of the pipe should be provided.

Education during the installation of random scratches and cuts on metal-plastic products is not permissible. For the same reason, when unpacking the bay with a metal-plastic pipe cannot be used a sharp tool. And to mark the pipe you need to use only a pencil (marker).

If you perform installation and connecting metal-plastic pipes according to the rules set forth in the article, you can organize a water supply system or heating that meets all requirements. The pipeline is laid independently, there will be a long time to prevailing the functions assigned to it.

If you decide to save during the repair work, it is better to do everything yourself. For example, communicate using metal-plastic pipes can be performed perfectly. The main thing is to prepare everything you need and familiarize yourself with the advice of specialists. And then you can proceed to work. This article tells how to carry out the installation of metal-plastic pipes with their own hands.

Preparation

Before starting to install, it is necessary to prepare the necessary tool and fixtures. Here everything will depend on the method of connecting pipes you choose.

There are two main ways to dock:

using compression fittings;
with the help of press fittings.

The first option is faster and does not require the use of a special tool. If installation is carried out using press fittings, then it is necessary to purchase or rent a special device - press clamp.

So, if you chose the first version of the fittings, then you will need the following:

for cutting pipes, you need to prepare special scissors or hacksaw;
set of wrenches;
grinding paper fine-grained;
special tool for giving pipes proper round shape (sweep or calibration);
metal plastic pipes.

If you decide to use press fittings, then it should be used to buy (or cheaper to rent a press tick. This tool can be both automatic and manual.

Connection using a compression method

This method is the most common, although some experts do not praise it. The fact is that compression connecting elements over time are "loosen" and leaks appear. Therefore, it is necessary to periodically inspect the locations of the docks, and if necessary, tighten the nuts.

The manual for the connection of metal-plastic pipes using compression fittings looks quite simple. All work is performed in the following sequence:

first, it is necessary to straighten the pipe on the stretch of ten centimeters in each direction from the place of the joint;
we place the location of the cut and perform it with special scissors or hacksaws. It is necessary to do it strictly at right angles;
then, the ends of the pipe are grinding with sandpaper to remove burrs. After that, calibration is performed using a special tool. This operation is necessary for ledging the pipes of the correct round shape;
now it is necessary to moisten the flange fitting, so it will be easier to dress on the pipe. It is necessary to wear it at the end so that the pipe evenly touches the fitting. Together with the flange on the end, a compression ring is dressed;
then two keys are taken and the nut is twisted with them. The first turns can be done manually. Nut must go easily. If this does not happen, then, most likely, you did not get into the thread. You need to unscrew the nut and try again;
after that, you need to experience the collected area to flow.

Conducting a combination of metal-plastic pipes using a compression fitting, a lot of effort is allowed. If you strongly tighten the nuts, then you can damage the fitting, which will leak up and in the need to replace the node.

Note! If the tightness of the connection is insufficient, then you just need to slightly pull the nut.

We carry out a press installation

A more reliable and durable compound is the docking of metal-plastic pipes using press fittings. True, this method makes the compound in displaceable, which may prevent the repair or reconstruction of the system.

The work process itself is as follows:

the pipe is straightened and marked;
pipe cuts;
the end is processed using grinding paper, sweep and calibration is carried out;
then the crimping clutch is put on the pipe, which is included in the fitting;
next, you need to wear an insulating gasket for fitting. It is necessary to protect the adaptation from the electrocorrosion;
then the fitting fitting is inserted into the pipe and crimped with press ticks. It is necessary to do it carefully and carefully not to damage the connecting device. Otherwise, you will have to cut the pipe again and carry out all the procedures again.

Check the correctness of the connection can be in appearance of the coupling. Two uniform rings should appear on its surface. If the crimp is incorrect, it is impossible to repeat it. It is necessary to trim the pipe and carry out all the work again.

Montaja rules

In order for the connections and the whole system to work properly and without the appearance of leaks, some installation recommendations must be observed:

installation work should be carried out at ambient temperature not lower than + 10ºС;
if during the transportation of metal-plastic pipes, they were in minus temperatures, then before installation, they must be kept in a warm room for at least a day;
metal-plastic pipes are desirable to lay in a closed way. If it is impossible, it is necessary to provide protection from mechanical exposure and ultraviolet radiation;
if there is a welding during repair work, it must be finished before the installation of metal-plastic pipes started;
you can not allow twisting or excessive bending of the pipe. According to the manufacturers's recommendations, the bending radius should not exceed the five pipe dimers. The bend itself can be done manually;
since the pipes are quite flexible, it is necessary to make them fastening. Fasteners are carried out every half-meter with a horizontal location and each meter with vertical. This uses special fastening clips;
if there is a need to pave the pipe through the wall, then you need to use the sleeves.

If, when installing systems using metal-plastic pipes, comply with these recommendations, then the communications will serve for a long time and do not cause you problems.

Video

In this video, you will see how metal-plastic pipes are installed using compression fittings.

Metal-plastic pipes are increasingly used for the pipeline device. These products are advantageously different from the analogues represented by the modern market. First, the inner layer is made of compacted or crosslied molecular polyethylene. Secondly, products have an aluminum layer. Thirdly, metal-plastic pipes are resistant to corrosion and do not require ideal accuracy in calculating linear dimensions.

Features of the system wiring

Installation of metal-plastic pipes for water pipes begins with the installation of ball valves, which are located on the junction. Cranes should have high quality in order to have the ability to operate at high pressure within 60 atmospheres, while the maximum temperature can be equal to 150 ° C. The installation of the water supply is carried out in a specific sequence: first the filter is installed, which will ensure deep cleaning, and the counter, then the fine cleaning filter and pressure reducer. Installation ends with a collector installation, from which the layout is made to the plumbing devices.

Installation of metal-plastic pipes for water pipes is carried out with the filters to protect the equipment and pipes from small particles of metals, sand and scale. After all, all this is present in risers in significant quantities. In order to ensure uniform water supply, a collector is installed. Usually this node has up to 4 inputs. If the number of instruments consuming is more, then the collector should be chosen, which corresponds to this indicator.

Fittings for metalplastic

The system of metal-plastic pipes is arranged using fittings that can be screw or pressed. The first are also called compression, and the second are press fittings. With the help of the first connection, it is carried out according to a specific technology. In this case, a pressure principle that occurs when the nut is twisted on one open ring.

To perform such connections, special tools are not required. The connection can be made by two wrench. One of them you will delay the nut, whereas others have resistance. If metal-plastic pipes are used during wiring, their laying should be used to the device consuming from a collector with one thread, the unnecessary compounds should be excluded.

After a certain time, you may encounter the need to pull for the tightness of the compound of fittings. However, if the pipes are laid in the floor or closed with tiles, the execution of the operation or dismantling will become difficult. In order to eliminate the periodic breakdown of the connections, press fittings must be used.

Features of pipe connection using press fittings

Installation of metal-plastic pipes for water supply can be carried out with their own hands using press fittings, they are durable and durable, and the warranty for their operation reaches 50 years. Pressure that can withstand these fittings reaches 10 bar, and the wiring can be made easily and quickly. Pipes in this case are connected using a press machine, which is a tool for installing pipes and may have manual or microprocessor hydraulic control.

The pipe for the connection must be cut off with special scissors in such a way that a direct angle formed. Using the scan and a special tool for calibration, you should remove the chamfer, and the diameter is adjusted for the subsequent installation. A stainless steel sleeve is put on the end. Up to the stop in the fitting pipe, the shaped part is established. The sleeve should be captured by the press clamp, which can be hydraulically or manual. The handles of the press are driving until it stops.

Montaja technology

The pipeline from metal plastic is mounted according to the technology. Since the pipes are sensitive to the effects of ultraviolet, thermal damage and mechanical effects, installation must be carried out neatly. Open gasket is permissible only in those places where the impact of the above factors is absent. With a hidden laying, the technology provides a device for removable shields and hatches to access compression fittings. Such shields and hatches should not have sharp protrusions.

Installation of metal-plastic pipes for water pipes with their own hands through the designs of buildings is carried out using sleeves. Their inner diameter should be greater than the external diameter of the pipe 10 mm maximum. The gap formed at the same time is filled with a non-aggravated soft material that ensures the movement of pipes in the longitudinal direction.

On the surface of the products there should be no cuts and scratches when system device. When unpacking the bay should not use sharp items. When you mark the pipe, you should use a marker or pencil. Installation of water pipes from metalplastic pipes with their own hands is carried out using suspension or supports that will allow mounting to vertical surfaces. These challenges can be purchased with pipes.

If the mounts are made of metal, then they are complemented by soft gaskets. The pipeline will be ready to serve longer if you provide its full tightness and do not allow damage.

Additional installation features using fittings

The most common devices for wiring are fittings that help connect different parts of the pipes. They have the most different forms that depend on needs, among other fittings, it is necessary to allocate:

coupling;
tee;
corolnic

Metal plastic tube before starting work is reproduced on separate segments according to the project. To do this, use special ticks that allow you to get a smooth cut. Some homemade masters use other devices for this, but specialists are not recommended to do this, since in the process you can damage the inner layer.

At the next stage, corners and tees are prepared for which seals are worn. Usually they are made of rubber, but on sale you can find products from other materials. These rings protect the system from leaks. For further work, there may be calibrators that are putting the holes to install the fitting and not bend the seal rings.

Plumbers advise to check the walls of the pipes before the start of installation: they must be smooth and clean. It is important to exclude burrs on cuts and other irregularities. If they are available, then defects need to be removed using sandpaper and wipe the slice with an alcoholic solution that will allow to degrease the surface.

The assembly and installation of metal-plastic pipes with their own hands in the next stage provides for the installation of fitting into the pipe. She is put on her nut and clamping clamp, which is suitable in diameter. The pipe for this is a bit stretched with the help of a calibrator, and the foot of the node is put on its end. It must be moved inside and fasten at the desired depth. The connection site must be smooth.

After the installation is completed, you must check the location of the fitting in the pipe. Now you need to tighten the nut on the metalplastic pipe. And there is no effort to make too much effort, because there are often cracks in communications. The tightening must be strong enough, but you should not pinch the nut. As soon as she starts crackling, you must understand that it fell tightly tightly on the pipe.

Additional recommendations for the use of press fittings when installing water supply from metal plastic

If you decide to use press fittings in the work, you should know that compared to ordinary they have a number of benefits. First, they are ideal for installing and laying the system, heated towel rail and gas pipelines. As their main plus, it is the fact that they do not provide for the need for periodic repairs, which distinguishes them from screw analogues.

Methods of work

If the installation and combination of metal-plastic pipes is carried out using press fittings, then you must trim and clean the product, which is a very important step, because the effectiveness of the entire subsequent work depends on it. After trimming pipes using calibers, it is necessary to reveal the product to the diameter that is necessary and removed. A steel sleeve is put on the pipe, and the fitting is located inside.

With the help of press equipment, it is necessary to hold the sleeve and fitting. This option will be ideal for pressure domestic pipelines that do not provide for the possibilities of periodic twisting. However, it should be attentive, because the dismantling of clamping fittings is quite problematic, so it is necessary to consider the plan and methods of branching the system.

How to bend pipe

The compound and installation of metal-plastic pipes provides for the need to change their turn. If you do not want to use special devices and want to reduce the number of fittings used, you can form a turn with spring, hands, pipe bend or with a hair dryer. In order to avoid defects, you can use the spring. It is available on sale in a wide range and is intended to solve the described task. The technology of mounting metal-plastic pipes for the water supply pipeline in this case provides the location of the product inside the spring. The size of the latter needs to be selected, taking into account the diameter of the pipe.

Changing geometry hairdryer

One of the effective ways is the use of a construction dryer. Under the influence of high temperatures, metal plastic becomes more supplied. However, to affect products in this way it is necessary to be carefully, because plastic can overheat.

If you are a novice master, then first you need to consider the methods for mounting metal-plastic pipes for water pipes with your own hands. And if necessary, bend one of these products is better to use pipe bender. He will suit those who have no experience in carrying out such works. With this device, bend the pipe will succeed without much effort and quickly.

Previously, the pipeline was associated with heavy metal pipes, with whom only the master could manage. Now the pipeline from metal plastic can be done with their own hands, there would be a desire. Step-by-step description of works with video will help you understand the basic principles.

Metal-plastic pipes - practical "sandwich"

Due to its design, metal-plastic pipes have a number of advantage over other materials for the pipeline. Their structure is such:

The inner layer consists of molecular polyethylene, stitched and compacted in a special way;
Glue layer, which fastens a polyethylene layer with aluminum layers;
Aluminum layer;
Glue layer connecting aluminum layer and outer plastic;
The last outer layer of plastic.

As you can see, the structure of metal-plastic products is similar to the complex sandwich, which combines all the strengths of plastic and metal. The advantages of such pipes You can describe in the following:

All these qualities are very rarely combined in one product, which is why metal-plastic as a pipeline material is very popular.

Caution! Unpack the bay with metal-plastic pipes without using sharp items in order not to damage their integrity.

Preparation of tools and components

As already mentioned, the installation of a pipeline from metal-plastic is possible and its own hands, you just need to know the basic principles.

Selection of components

The minimum required kit for a complete set of water supply from metal plastic is as follows:

ball Valves;
metal plastic pipes;
fitting.

Ball Valves

All begins with the installation of ball valves, the quality of which determines the safety of the entire pipeline. In case of leakage, the ball valve overlaps the water supply from the total riser in the apartment.

Attention! Avoid Chinese cranes, recognizing them on poor-quality casting.

Choose those models of ball valves that are able to work in the conditions in which they will be operated. It is best to take models that are designed for 60 atmospheres and 150 ºС.

Truck marking

Choosing pipes is very important to take into account the marking, which speaks of the conditions in which they can be operated. It is advisable to choose products with PEX or PE - RT marking, which are designed for high system pressure and easily withstand the hydrowards. Products with Marking PE-RS, PE-HD or HDPE have a lower price, but can only be used in low pressure systems. We do not advise you to equip the pipeline using such a material, since any hydrate can be destructive for them.

Fitting

Metal-plastic pipes are connected to a single system using fittings that can be three types:

Compression;
Presses;
Savory.

In practice, compression or crimping fittings are most often used, due to the fact that this requires only a wrench. This fitting can be used many times, it consists of nut, fitting and a split ring.

Press fittings are more reliable, therefore they are used to arrange hot water system. But for installation in this way you need to have special press clamps.

Saving fittings will also require special equipment - the expander, which is capable of expanding the diameter for installation.

Tools for work

To fulfill all the work need several uncomplicated devices:

Special components;
Pipe bender;
Calibrator;
Fatheck seater;
A pair of wrench keys.

The fake sequence will be necessary to prepare the end of the pipe for mounting. It removes a certain layer, making a chamfer. Without this step, it will be difficult to achieve a hermetic junction.

So that you can proceed to direct installation, you need to make a detailed diagram of the pipeline. It needs to be placed all the segments of pipes and connecting points, as well as other key items: filters, cranes, tees, and so on.

Water pipeline scheme

To improve reliable water supply from metal plastic, you need to know the sequence of installing certain nodes of this system.

Water pipeline scheme:

Inlet ball valve;
Coarse filter, which will stop large particles of dirt;
Water meter;
Filter of fine cleaning;
Pressure stabilizer that levels pressure in the internal system when jumps in the external water supply;
Collector that distributes water;
Direct layout of pipes from metal plastic to plumbing.

For metal-plastic pipes, the coarse filter is very recommended, since large particles may damage the inner layer of polyethylene. As is known, such particles, such as sand, metals or scale in our risers abound.

The collector evenly distributes water from the riser to the point of consumption: sink, toilet, washing machine, etc. These devices are equipped with several outputs, so you need to choose the model that will correspond to your plumbing scheme.

In the first place in working with metal plastic you need to put accuracy, because negligent treatment or coarse force can easily damage this material. It is impossible too tight and dramatically tighten the nuts, and also allow the appearance of scratches and cuts on the surface of the pipe. Before starting work, we recommend that you view a video clip on the installation.

Installation with compression fittings

The first thing, as already noted, we set the ball valve, allowing to overlap water in an apartment or a house.

Stages of the installation of the pipeline with their own hands:

Wiring using metal-plastic pipes must be performed whole line From the collector to the consumption point. It is not necessary to introduce unnecessary compounds, as compression fittings periodically need a broach, in order to preserved the tightness of the structure.

If you equip the warm floors, the presence of compression fittings under the floor is unacceptable, because their prevention will be unavailable. The benefit of metal-plastic pipes bend, and they can be paved in some form, avoiding unnecessary connecting nodes. In addition, there are press fittings that do not need a broach - durable and durable, they will provide quick installation and a guarantee of work up to 50 years. The following describes the installation scheme using such fittings.

Mounting with press fittings

Press fittings are able to withstand in the operating mode pressure of 10 bar. However, you will need at least a simple manual press machine for their installation, but there are hydraulic.

Mounting scheme with press fitting:

The first steps are completely coincided with the installation of compression fittings: cut off the pipe, as well as calibrate and remove the chamfer;
At the end of the pipe they put the sleeve of stainless steel;
Now you need to insert until the fitting part of the fitting is stopped;
The sleeve must be closed using a press machine;
Press handle reduce until it stops.

Here are some useful tips to help you. avoid major errors When working with metal-plastic pipes:

More tips for working with pipes can be seen on the video.

Water pipe made of metalplastic with their own hands can do even unprofessional, thoroughly studying the master class on the video. For this you do not need special expensive fixtures and special skills. However, despite the strength and flexibility of metal plastic, so that these pipes will serve you as long as possible, when they are installed, some rules must be followed. Video and tips in our article will help you to fulfill all the work on the installation of water pipes from metalplastic.

Water pipes made of metal-plastic pipes - the most common option of the "wiring" of the water supply in houses and apartments. They firmly reigned in this market segment. And there is good reasons for this.

On this page, we describe all the pros and cons of such a water supply, as well as in detail, we describe how to make metal-plastic pipes, how to connect them with fittings, etc.

Advantages and disadvantages of metal-plastic water supply

There are several objective indicators that allow metal-plastic pipes to shut up for the belt of their competitors when the water supply system in an apartment or house:

Easy installation. With careful work, they can be performed by any person without any preparation. Almost this semblance of a designer, for the assembly of which expensive tools and special skills are not needed.
Reliability. Warranty 50 years ago confirmation. But note that it applies to pipes, and not on their compounds.
Price. One can say one thing: "Cheaper, just for nothing." Some competition for this parameter can be polypropylene pipes, but otherwise they lose.

Based on the foregoing, the plumbing on metal-plastic pipes is obtained reliable, it costs it inexpensively, and you can collect it with your own hands. Naturally, connecting to the central system, it is the prerogative of professionals.

No matter how regrettable, but each honey barrel, there is a spoon of tar. In the case of metal-plastic water supply, these are fittings.

Fitting, this is a device with which you can:

In our case, we are talking about metal-plastic pipes. If the fitting at both ends has the same diameter, then it is straight; And if different, then transition.

But these are only their varieties for their intended purpose, but according to the method of fixation, all fittings are divided into crimping and presses.

Crimp fittings. Differently called ring, or served. In those, the fixation is performed due to the conical shape, the inner surface, the crimp nut, which, when twisting, compresses the edge ring. Such compounds can be disassembled and they require periodic maintenance. Usually once a year, crimp fittings on metal-plastic pipes for which flows hot water, It should be checked and, if necessary, tighten a little. The reason for their weakening is the temperature deformation from hot water. For their installation, two gas (adjustable) keys are required.
Press fittings. Or non-maintained, fixed on a pipe by pressing a special crimping sleeve. Work is made by press clamp. They can be manual or electric. In the first cost from 4 TR, the second from 25 tr. The compound is obtained indefinitive, but with a guarantee from leaks, regardless of water temperature. Most often, press fittings are used in connections that will be molded into the walls, or with difficult access after repair.

Reliability and quality of compounds depend on the scrupulousness of the execution of instructions. But at the price ... Although the press fittings are cheaper than the crimp, but their total cost for the water supply equipment in the apartment is equal to the costs of metal-plastic pipes.

We plan a water pipe "on paper"

The most important and primary, this is a plan of water supply layout. If you have never been engaged in this, then you can make it up with a clean leaf without much difficulties, although this is satisfied with the painstaking. But everything starts from the consumer.

It is necessary to mark the places in which the cranes will be. This is a kitchen and a bathroom. With competent construction, they are usually located nearby, which facilitates and significantly reduces the cost of the water supply system. In the perfect version, if they are in adjoint premises, only one pipe will be required, from which the tee will be taken offen in different rooms.
The place of arrival in the house of water is designated. There are only two options: central water supply or private well (well). Depending on this, additional equipment may be required. In particular, when using water from the well, it is necessary to install a hydroaccumulator (above the level of consumers). From it, water is self-shot to enter the house. Such a system is preferable, for it does not require constant inclusion of the pump. The hydroaccumulator does not have to be metallic. It can be "pouring out" from concrete. And already in the house mounted:
Filter system (equipment depending on water quality).
Boiler.

Accordingly, that if the water flows into the house from the central water supply system, then the input will require only controlling instruments to account for consumption.

This is a schematic diagram. Give recommendations on the filtration system, not knowing the quality of water, is not permissible. Also belong to the water heating system. Depending on the conditions, the boiler can be electric or gas. The use of a water heater on liquid or hard fuel is not economical and associated with certain difficulties. Especially in the summer.

Required tools and materials

From the cranes, the bempwint is unwound along the wall. In places of bend or branching, cloves are clogged, and the direction changes. Accordingly, that from tees, two (or three) bemps will already go. By placing the entire system thus, it is necessary to draw its location not the wall. Can be chalk or water-emulsion.

Only after that, the beep must be removed, and to measure its length. Additionally calculate the number of fittings and their types.

Important: The resulting Pipe Metrah, increase by 10%. This is common practice.

Regarding the selection of the diameter of the pipe, there are already a prevailing opinion. Almost for all residential buildings and apartments, with an excessive enough metal-plastic pipes ᴓ16 mm. It provides a flow of up to 3 m 3 / hour. And most water counters are not designed for greater flow. Yes, and why more?

The choice of the manufacturer of metal plastic pipe is perhaps the most difficult task. In the market often come across fakes. Purchase a pipe in a solid store or from proven suppliers. We recommend to refrain from the purchase of metal-plastic pipes of Chinese manufacturers. Negative reviews are found too often. The highest quality metal-plastic pipes are produced in Belgium ( Henco), Germany ( Frankische and Sanha.).

What will be required of the tools:

Cutter for metal-plastic pipe (from 250 p).
Caliber with zenker (from 200 p).
Conductor (from 500 p).
Press ticks (from 4000 r., But you can rent).
Two gas (or adjustable) keys.
A hammer.
Sculpture.

How to work with a tool

Caliber, restores the shape of the pipe after cutting, and Zenker removes the chamfer and removes burrs. If the caliber is without a zenker, then its work can be performed using shallow sandwich.

The conductor serves to flexing the metal-plastic pipe. It is external and inner. The use of internal in some cases is more convenient, for it does not slide in his hands. But it is not always possible, for the place of bending can be far from the end of the pipe. Therefore, we recommend to stay at the external conductor.

Press pliers will be required if you use maintenance-free fittings. We, on the basis of 16 years of experience, we recommend that the press fittings are recommended. And the reason here is one. Most tenants, in a year they forget about the service of crimp fittings. And this leads to leaks. But the choice is yours.

Consumables will require: self-tapping screws, fastening for metal-plastic pipes, tape FUM.

Mounting process of metal-plastic pipes

Starting the installation of metal plastic water supply is necessary from the source to the consumer (to the cranes). Make a cut from the roll to the nearest fitting, and cut it with a knife. Calibrate, remove the burrs and remove the chamfer. Then insert the pipe into the fitting until it stops. The press fittings have special holes, to control the depth. They should be visible the edge of the metal-plastic pipe. Then insert the fitting into the ticks, and crimp the connection.

Crimp fittings are fastened with nuts and rings included in the kit

It is quite simple to work with the press ticks, because insert the fitting "Crooked" will not work.

All press clamps have replaceable sponges for pipes of different diameters. Do not make mistakes in choosing sponges.

The process of installation of crimp fittings is slightly different. The nut first puts on the prepared trim, then the edged ring and after that, the pipe is inserted into the body of the fitting itself. Before spinning the nutWe strongly recommend that turning the fum ribbon. It takes only two or three turns. It is necessary to start from the edge of the thread and carry out the winding, holding the latitude tape. After that, moisten the thread with sunflower oil. This technique will protect against the appearance of leaks!

The nut is first twisted with their hands until it stops. And only then, holding the fitting with one gas key, others tighten the clamping nut. It should not be drawn out of all the might, but the small effort is needed.

Installation with press ticks

Fix the metal plastic pipe to the wall follows each meter. Special attachments through the self-sufficiency are strengthened in the surface, and the pipe is inserted into them.

In those places where it is permissible, the pipe can be bent using a conductor. To do this, the conductor dresses onto the pipe, supply it from the right place, and neatly, holding the product with his hands, on an equidistant from the target distance, bend the pipe in the desired plane. Given that the radius of the bending of the metal-plastic pipe is equal to its 8 diameters, this approach is not expedient everywhere.

Checking, leakage

By installing metal-plastic pipes, connect them to the crane with the help of hoses that are included. Then go through all the route again, and visually check the integrity of the assembly.

Pay attention to tees and splitters. Sometimes, inserted by one branch, the installer forgets about fixing the pipe in another.

Open the taps at the end of the water pipeline (in the kitchen and in the bathroom). And only after that slowly, in order to avoid a possible hydrate, open the water supply faucet to the system. It is most convenient to perform this stage with a partner. It should control the water outlet in the final point. As soon as the water went, for washing pipes, let it drag it within 2-3 minutes. Then close the outlet cranes, by this you raise the pressure in the system, and go through the pipe of the pipe gasket. Check all connections. If you doubt, do a paper napkin (or toilet paper) on the surface of the fitting connections). Do not confuse condensate with leak!

We guarantee that if you fulfilled work according to our recommendations, then in 99.9% there will be no leaks. If a connection causes you a reasonable fear, then slightly tighten it.

Plumbing from metal-plastic pipes with their own hands video

Detailed instructions for installing metal plastic pipes and compounds by their fittings. All about how do it yourself collect water supply in an apartment or a house with a video

How to make the installation of metal-plastic pipes with their own hands

In the life of a modern person, an important place is occupied by the transfer of various substances, in particular, water, by the distance using the supply systems - pipelines, the most important and extended part of which are pipes.

Due to the wide range of products today, each host host has the opportunity to independently assemble the water supply system using products from any suitable material. This article will tell about the installation of metal-plastic pipes for water supply with their own hands, characteristics and advantages of such products.

The device of pipes from metal plastic and their advantages

Products of this type consist of three main layers and two sucks, from the inside to outward:

The layer of molecularly compacted or cross-linked polyethylene.
Glue layer between the inner layer and aluminum foil.
Aluminum layer.
The glue layer connecting aluminum and the outer layer of the polymer substance.
Outer plastic layer.

Advantages of products from this material:

relatively small, compared with metal elements, weight that makes it greatly facilitating all operations for maintenance, planned or unscheduled repair, dismantling and installing metal-plastic pipes;
lack of corrosion threats, since the inner and outer layers of products are made of plastic not destroyed under the influence of water;
thanks to the reinforcement of aluminum, the linear expansion coefficient is very low;
the consequence of the previous point is the ability to do not withstand the ideal accuracy during the calculations and preparation of products.

Among the shortcomings of metal-plastic pipes, the following can be distinguished;

their mechanical strength and resistance to overloads is still less than that of metal elements;
the upper thresholds of operating temperatures and pressure are also not so high.

A few words about the wiring of the water supply system

Wiring of metal-plastic pipes with their own hands as a whole is simple; The process begins with mounting on rising ball valves. At this stage, it is necessary to especially carefully select fittings, giving preference to high-quality products suitable for use at least 60 atm. and temperatures about 150 ° C.

It is clear that, since, for the quality of Chinese products, no one can vouch for and bring it at any time, it is best to avoid acquiring it, stopping on more expensive, but reliable versions.

Especially this is essential, if we consider that it is precisely through the ball cranes in the event of a leakage of the system overlap the flow of water into the apartment.

Selecting good cranes and installing them, you can continue to mount the plumbing from metal-plastic pipes with your own hands.

The following preparatory stages of water supply system arranged:

Installing a filter for deep cleaning and watercolor.
Installation of a filter intended for fine cleaning.
Introduction to a pressure reducer circuit.
Installation of the collector, from which the metal pipes will be discharged, connectable by various methods and subsequently connected to the instruments of the plumbing destination.

Despite the fact that the inner surface of stitched polyethylene is sufficiently resistant to the effects of small abrasive particles, the installation into the system with metal-plastic pipe filters is necessary: \u200b\u200ba large amount of sand, metal particles or pieces of scale can damage not only the pipeline, but also output devices.

The collector must be assembled to provide the same intensity to supply moisture from a common riser to all sanitary cells - sinks, washing machine and toilet bowl.

Usually in the collector is provided from two to four outputs. If there are more devices in the house in the house, it is possible to select collectors with an appropriate amount of outlet.

Fittings for metal-plastic products

The most important question that should clarify the home master is how to assemble metal-plastic pipes. Usually, special connecting elements are used for this purpose - fittings.

They are two types:

Press fittings (mounted presses).
Screw (compression type).

Mounting features with compression fittings

These products are characterized by:

the strength of the compound is ensured by the pressure of the knurable nut on an incurred crimping ring;
the lack of need to look for special tools for connecting pipes: just two wrench keys, one of which hold the place of installation, and the other tighten the crimping nut;
the need to apply with the laying of metal-plastic pipes with their own hands as little intermediate connections;
the possibility of gradually loosening the strength of the connection, as a result of which it is necessary to stretch the crimping nuts from time to time; Because of this, stacked the pipes mounted in this way in the walls or floors is not recommended.

You can avoid the last problem by replacing crimping products with press fittings.

Mounting features using press fittings

Such products are more reliable and durable (service life is at least 50 years), withstands working pressure up to 10 bar and provides ease of installation of the pipeline.

The only drawback is the need to apply a special press machine, manual or hydraulic with a microprocessor.

Sliced \u200b\u200ba piece of pipe of the desired length.
Remove the face with the ends and customize the diameter of the product.
They put on the end created from stainless steel sleeve.
Paste the prepared part of the pipe with the fitting until it stops.
The gripping of the press car take a sleeve and compress it, pulling the press handle.

For the connection to be durable, you should follow the following rules:

pipes do not tolerate ultraviolet rays and mechanical damage, so it is possible to put them in the open way only where there are no these factors (read also: "How to build metal-plastic pipes - step-by-step management of the compounds");
with a hidden gasket, it is necessary to provide access to fittings, providing for the installation of various windows and removable panels during installation;
when you need to spend pipes through the house designs, select the sleeve with a diameter, large by 5-10 mm of a similar external parameter of the pipe. The gap creates a non-combustible material, which, when squeezed, contributes to the longitudinal promotion of the pipe;
when mounting products on the walls, use the suspension and supports supplied by the same manufacturer, and the metal parts of the fasteners areolate with a soft material;
it is impossible to allow damage to the product surface.

In compliance with these tips, the assembly of the water supply system will be simple and not particularly expensive.

Installation of metal-plastic pipes: water pipes with your own hands, how to fix, gasket, water supply, installation

Installation of metal-plastic pipes with their own hands

When performing pipelines of any type of water supply today, the installation of metal-plastic pipes is successfully used.

Metal plastic pipes due to their design have a number of advantageous advantage of them from other types of similar products.

Assembling metal-plastic pipeline

The advantages and device of pipes from metalplastic

Constructively in metal-plastic pipes there are five layers:

The inner layer of the product is made of cross-linked or compacted molecular polyethylene;
The glue layer connecting the aluminum layer and polyethylene;
Aluminum layer;
The glue layer connecting the aluminum layer and the outer layer of plastic;
Layer of plastic.

Metal-plastic pipes have certain advantages relatively with similar products:

Metal-plastic pipes due to the polymer layer have high corrosion resistance.
Thanks to the layer of aluminum, the products are elastic and retain the form, whereby the installation of metal-plastic pipes of almost any complexity and configuration is possible.
Ideal accuracy in calculating linear dimensions is not required.

Features Watering Watering System

Montage with your own hands of metal-plastic pipes starts with a device of ball valves on a riser. For installation, it is necessary to choose exclusively high-quality ball valves that are capable of operating at high operating pressure (within 60 atmospheres) and a temperature of 150 degrees.

Chinese fakes should be avoided, because in the water supply system, much depends on the quality of the cranes.

It is the ball crane in a situation with the appearance of leaks, you can overlap the flow of water in the apartment.

Ball cranes for metal-plastic pipeline

Scheme of a metal-plastic pipeline system

Deep cleaning filter and water meter;
Filter of fine cleaning;
Pressure reducer;
The collector from which the layout is made and the installation of pipes from metalplastic to directly plumbing devices.

Metal plastic pipes are mounted together with filters to secure plumbing devices and the pipes themselves from small particles of sand, metals, Okalin present in risers in significant quantities.

The collector installation is required to ensure uniform water supply to consuming elements - sink, toilet bowl, washing machine, from a water rummer. As a rule, collectors have 2, 3 or 4 outputs. In the event that the number of consuming devices more than four, select such collectors that have the required number of outputs.

Pipes for pipes from metalplastic

If metal-plastic pipes are required - installation and immediately compound is performed using fittings for metal-plastic pipes, which are the following types:

Connection of pipes by compression fittings

Scheme of compression fitting

Completion with compression fittings:

In the case of applying a compression fitting, the compound is obtained by pressure occurring in the process of spinning the nut on the crimping open ring.
To perform a compression connection, special tools for mounting metal-plastic pipes are not required.

The connection is performed using two wrench: at the time when one is tightened to the nut, the other key is resistance.

If, when performing a wiring, metal-plastic pipes are used - the installation should be made to the device that consumes from the collector with one "thread", avoiding unnecessary connections.
After a while there may be a need for a broach to maintain the tightness of the compression fittings.

But if we put into the floor or close the pipes with a tile, having several fitting connections, then the performance of this operation or dismantling of metal-plastic pipes in the event of such a need to become very difficult.

To avoid periodic feeding of fittings, you will not remain anything, how to mount metalplastic pipes with press fittings.

Compound of pipes from metalplastic with press fittings

Press fittings are durable and durable (the warranty on them is up to 50 years), can withstand pressure up to 10 bar, and produced by their help of metal-plastic pipes is performed quickly and easily.

Metal-plastic pipes with compound press fittings are installed using a special press machine. This tool for mounting metal-plastic pipes is simple manual and microprocessor hydraulic.

Instructions for installing metal-plastic pipes with compound press fittings:

The pipe is cut off with special scissors at right angles.
Using a scan and a special tool for calibration, the chamfer is removed, and the pipe diameter is adjusted for the subsequent installation.
A sleeve made of stainless steel is put on the tube.
Up to the stop in the fitting pipe, the shaped part is inserted.
The pressure clamp - manual or hydraulic - the sleeve is captured.
Before the stop, the handles of the press are reduced.

Rules for laying of a metal-plastic pipeline

The pipeline from metal plastic is paved in accordance with the following rules:

By installing metal-plastic pipe, it is necessary to observe emergency accuracy, since the pipes are very sensitive to the effects of ultraviolet radiation, mechanical and thermal damage.

An open gasket of such pipes is permissible exclusively in such places where there is no impact of these factors.

Mounting technology of metal-plastic pipes with a hidden gasket provides for the device of hatches and removable shields to access compression type fittings. Such hatches and shields should not have sharp protrusions.
Installation of pipes through the designs of buildings is carried out using a sleeve with an inner diameter, by 5-10 mm exceeding the outer diameter of the pipe.

The gap that is formed at the same time is filled with a soft non-aggravated material capable of ensuring the movement of the pipe in the longitudinal direction.

During the device of metal-plastic pipes for water supply or heating at each stage, it is necessary to remember the inadmissibility of the occurrence of scratches or cuts on the surface of the pipes.

Example of a household water supply system scheme

Unpacking the bay with a pipe, do not use sharp objects. When the pipe is marked, you must use exclusively a pencil or marker.

Metal-plastic pipe installation is made by means of supports or suspensions, with which the mounting to the wall is performed.

Supports and suspensions are offered by pipe manufacturers. Metal fasteners need to be equipped with soft material gaskets.

The pipeline from the metal plastic, made by its own hands, will last longer if the tips, instructions and recommendations will be fully respected.

Installation of metal-plastic pipes with their own hands: Compound technology + wiring examples

Modern materials for the arrangement of domestic highways made it possible to independently assemble water supply and heating systems. For example, the installation of metal-plastic pipes with their own hands allows you to arrange a tap or sewer wiring. To work with such elements, no complex tools or special skills are required.

Features of metal-plastic products

Metal-plastic (metal-polymer pipes) are composite products, for the production of which various types of materials apply. Such elements have an attractive appearance, good wear resistance, elasticity, strength.

As a rule, the pipe consists of five layers. A durable polymer is used as a carrier base, usually stitched polyethylene. It gives the smoothness of the inner surface, protecting it from blockages, and also contributes to the strength of the product.

An adhesive substance is applied to the core, on which the aluminum foil stabilizing pipe is strengthened (it also prevents oxygen intake). The connection is secured by welding online or brass.

The fourth layer is also applied with glue, to which the outer coating is connected - white polyethylene, providing the product with protection and aesthetic appearance that gives it aesthetic appearance.

Technical characteristics of pipes D 16-20 mm

We present the data characteristic of metal-plastic pipes of common diameters (16 and 20 mm):

The wall thickness is respectively 2 and 2.25 millimeters; The thickness of the aluminum layer is 0.2 and 0.24 mm.
One run-down meter weighs 115 and 170 grams and accommodates the volume of liquid equal to 1,113 and 0.201 liters.
The coefficient of thermal conductivity is 0.43 W / m to, the expansion of the metalplastic - 0.26x10 4 per 1 degree Celsius, the coefficient of roughness - 0.07.
With the transverse break of the material, the strength coefficient is 2880 H.
The adhesion strength of the adhesive layer with a foil is 70 H / 10 square meters, the strength coefficient of the aluminum welded layer - 57 H / sq. mm.
Metal-plastic pipes can even work at +95 ° C, briefly withstanding the temperature + 110-130 o C.
In the temperature boundaries from 0 to +25 o, the system functions at a pressure of up to 25 bar, and at +95 ° C withstands the pressure of 10 bar.
The tightness and integrity of the metal-plastic pipe is broken under the load of 94 bars (at +20 ° C).

With the right installation and observance of the operational rules, the product from metal-planes can serve as 50 years and more.

Advantages and disadvantages of metal-polymer

The advantages of such products can be attributed:

eastern of installation: Compounds of various categories of metal-plastic pipes are carried out quickly and easily;
high heat resistance (can be transported water heated to 100 ° C);
reasonable price (metal-polymer pipes are cheaper than metal and most plastic analogs);
high strength, ring rigidity;
corrosion resistance, aggressive environments;
no clock to the formation of sediments and blockages;
aesthetic appearance;
high bandwidth;
low thermal conductivity;
sufficient plasticity;
the possibility of light repair;
durability.

The main disadvantage of such products lies in the fact that the metal and plastic, of which they consist of pipes, have different expansion indicators. Regular temperature differences of the agent in the pipes can lead to a weakening of fasteners, which is why there are flows in the design.

To avoid this, experts advise, making installation, always provide a certain supply when joint joints. It will also be useful because metal-plastic systems are poorly withstanding the hydrowards.

Scope of application of metal-plastic elements

Pipes made of metal-polymer are widely used in the arrangement of individual houses, in industrial construction and agriculture.

The main areas of their use are:

transportation of liquids, gaseous agents;
laying of drainage systems, water pipes, heating;
in structures involving the transfer of compressed air;
podding the components of heating to radiators, a warm-alone device;
installation of air-conditioning schemes;
protection and shielding of wires (primarily power);
the structure of watering systems.

when organizing central heating systems with an intended device of elevator nodes;
in places with a prescribed fire safety level "G";
with the intended supply of hot liquid in the pipeline with a working pressure\u003e 10 bar;
in rooms where it is planned to place the sources of thermal radiation with a surface temperature of above 150 degrees C.

In addition, metal-polymer pipes are undesirable to use in safety, signal, overflow, expansion schemes and in fireproof water pipes.

Three main ways of pipe wiring

Wiring of metal-plastic systems can be carried out by different methods, each of which is chosen on the basis of the feasibility and possibilities of further access to the system.

Option # 1: Hidden

In this case, all pipes and connections are hidden in the depth of the wall under finishing materials. Alternatively, only fittings and taps for connecting plumbing devices are displayed.

When using this method of installation, the interior design is preserved, in addition, the masking of communications protects them from random damage.

This option has several minuses:

To lay the channels for pipes, a complex and time-consuming process of sticking is required. After laying communications, the surface has to restore again.
Such a way is not suitable for bearing walls, where it is forbidden to carry out the launch of regulatory documents.
A fairly high cost associated with extension work.

This way it is better to take advantage of the repair in the bathroom. It is impractical to arrange a hidden gasket in the already decorated room, since it will take a complete dismantling of the wall covering (facing, plaster).

Option # 2: Open

If the pipes for any reason can not be covered in the wall, they can be paved along its surface. This option is more convenient for visual control over connectivity places, which allows you to quickly clean the site or replace the component.

An open layout can be used in rooms with already repaired, since the installation will not harm the design of the walls. The advantages of this method include its ease and lower cost of work than when laying internal communications.

Option # 3: Combined

In this case, the pipes are carried out on the surface of the indistened walls, after which they are closed by boxes or false panels. This is a rather complicated way, since it requires perfect fit into the interior of decorative elements, which can also use plasterboard, tiles and other materials.

Schemes for bathroom and bathroom

With plumbing works carried out in bathrooms and toilets, three layout of metal-plastic pipes can be used. For private houses, the use of the collector is the most rational.

Effective collector system

A reliable and practical option involving the connection of each object to the central tube through the entrance pair. This allows the crane to adjust or turn off the water supply to each specific plumbing.

All regulatory devices are located in a compact manifold, which is placed in the space specifically allocated to them (cabinet).

Drinking pipes that have a minimum of compounds do not require special control, which allows the gasket to be laid in a hidden way. The disadvantage of this option is quite high cost, because for each connection you will need to purchase a special shut-off crane. Since such a system is quite complicated, it is necessary to produce neatly and carefully.

An important advantage: in case of failure of a separate item (washing machine, mixer), there is no need to completely disconnect the bathroom from the water supply - it is enough to turn off the desired shut-off valve.

Sequential system of connections

This option involves the connection of each SANTEXPEDMET to the main pipe with a separate tee. It is more suitable for bathrooms with a minimum number of objects (washing machine, a common mixer).

The consistent scheme can be implemented already after completion in the room of finishing, using an open laying system. The assembly process is quite simple: the pipe is laid from one item to another, at the same time the underlining element is displayed from the tee.

This option requires minimal financial costs. It should be noted that with a large number of points for the fence of the pressure fluid may not be enough, and the system will function with difficulty or even fail.

Wiring system with passage sockets

Connecting plumbing devices is similar to consistent, but instead of tees, outlets are used. This scheme is usually applied only in individual houses, since it requires a large-length pipe laying, as well as the installation of an additional pump, which will help ensure the necessary water pressure.

When performing connecting works with metal-plastic pipes, several important nuances should be taken into account:

When developing a design, it is desirable to provide for at least connections.
It is important to apply the pipe and connecting couplings made from the same material.
For the pipeline it is better to use thermal insulation that allows preventing condensate sedimentation.
It is necessary to provide free access to the accounting devices, filters, detachable connections.

Compliance with the rules will create a reliable system capable of listening for many years.

Wiring of sewage pipes

The work on the installation of sewage metal-plastic pipes has its own features.

In this case, it is important to comply with the following requirements for the unobstructed drainage removal with blockage prevention.

To withstand a slope (0.02-0.03 from the holistic length of the design) towards the drain collector.
It is forbidden to put taps at an angle of 90 degrees when installing structures.
The need to install special tees with removable lids (revisions) in areas before turning inclined to form blocks.
When laying the system with a hidden way, it is important opposite the audit to leave viewing windows.
Collecting the system, it is important to leave a stock intended for the temperature expansion of the product.

To install sewage, it is necessary to use pipes, the diameter of which ensures easy wastewater permeability. For the toilet bowls, it is recommended to use products with a diameter of at least 100 mm, for baths and sinks - enough 50-75 mm.

Rules for installation of metal-polymer structures

When laying metal-plastic systems, it is important to be guided by the following provisions:

With a hidden laying of pipelines from this material, it is important to provide removable shields (hatches) devoid of sharp protrusions. They provide access to compression fittings.
Stacking systems through structures of buildings It is important to produce with the help of a sleeve, the inner diameter of which is 0.5-1 cm more similar to the pipe parameter. The gap that is formed between the elements must be filled with a soft non-combustible material that ensures the movement of the pipe in the longitudinal direction.
When laying metal plastic water supply or heating systems, it is important to prevent damage to the surface of the elements, including scratches or cuts. To unpack the bay, it is better to avoid sharp objects, and the design markup is performed with a pencil or a marker.
Installation of construction can be carried out using support or suspension, which are usually present in the range of metal-polymer pipe manufacturers. They help attach products to the wall, while the metal parts are installed with gaskets made of soft material.

All stages of operations need to be carried out carefully and neatly, since metal-plastic elements are sensitive to ultraviolet, mechanical damage. The outer installation of such structures is appropriate only in places where there are no similar factors.

Tools and materials for pipe gasket

For laying metal-polymer systems, minimum devices and materials are required, but it is better to choose high-quality devices and pipes.

Fixtures for mounting pipelines

To create a construction of metal-plastic, a fairly modest set of tools: pipe cut, the simplest pipe bending, sliding and precipitated keys.

Truborez is needed to separate dimensional cuts of the pipe from the bay. Since metalplastic is sufficiently supportive material, it can be cut with a metal knife or even a sharp knife. However, the perfect perpendicularity of lines, without which it is difficult to obtain a hermetic compound, can be obtained only when using a special cutter.

The keys of different species are important for installation and assembly of threaded connections on pipeline fittings. With an extreme need, you can do with one precipitant key, however, it is better to use two precipitated and one-aligned key for comfortable work.

Caliber is an important tool for creating an accurate and sealed connection of the pipe with a fitting: it allows you to center the plane of the slice and remove the champecker from the inside of the product.

The pipe bender allows you to change the configuration of the element, which can be saved on the corner fittings. It is especially important to have this tool if the design involves a large number of angular conjugations.

What materials are required

For laying the pipeline, it is important to stock in the following components:

pipes (bay, measuring segments);
various options for fittings (bypass, tees, corners), with which certain areas of pipes turn into a single system;
fasteners - folding clamps and clips, with which metal-plastic structures are fixed on support surfaces, most often on the wall.

It is important to choose all the necessary materials and tools in advance, to then freely exercise all the work.

Marking of pipeline lines

Before starting work, it is important to consider how pipes will be placed. When developing a scheme, it is desirable:

Apply the lines of the pipeline directly on the walls of the room, where it is planned to lay, which contributes to the visualization of the structure.
As the starting point, use the plug connection area to the crane or the radiator, which must already be installed before the installation.
Minimize the number of tees and crosses affecting the stability of the pressure, as well as minimize the number of other fittings.
For the corner laying of metal-plastic pipes, you can use pipe bend or corner fittings.
All connecting element should provide free access, as the fasteners on the thread need periodic pulling into order to avoid leaks.

Installation of connecting elements must be performed after the calculations and markup of the structure.

Fittings Review for Metal Flast System

To prepare for work, it is important to cut the pipes to the sections required for the length, while all the cuts should be carried out strictly at right angles. If in the process cutting the pipe is deformed, it must be aligned with a caliber (it will help to remove the internal chamfer).

For the installation of the design, various types of fasteners apply, we will stop separately.

Option # 1: collet

Collet fittings, consisting of a housing, crimp ring, rubber gasket, have a detachable design, so you can apply several times. The carving of parts allows you to combine them with household appliances.

To connect the connecting elements to the pipe, you need to wear a sequential nut and ring. Insert the resulting structure into the fitting, tighten the nut. To make the pipe easier to the connecting element, it is desirable to moisten.

Option # 2: Compression

Widely used parts used for connecting pipes that can be called concentrated. Before installation, it is important to make sure that the sealing rings and the dielectric pads, which must be on the part shank.

To connect to the end of the pipe, a nut and a crimp ring is put on (if it has a cone form, then the process is carried out with a narrower side of the part). After that, the shank is inserted into the pipe (for this you need to make some effort), while in order to seal items, the part is covered with packles, flax, sealant.

The next step on the fitting body is put on and tightened by a cape nut. It is convenient to do this with the help of two keys: one of them is fixed the item, another nuts.

This method is sufficiently easy and does not require the use of special equipment, but it is undesirable to apply for hidden wiring, since it requires a connection check.

Option # 3: Push fittings

Comfortable connecting elements, for fastening which special tools are not needed. To install, it is enough to insert the product into the connecting part, while the end of the pipe should be visible in the viewing window.

Immediately at the end of the installation, thanks to the enabled water jet, the fitting wedge pushes forward, forming a clamp that prevents leakage.

This method allows you to quickly and easily create the necessary design, providing high-quality durable connections. Almost the only lack of push fittings is their high cost.

Option # 4: Press fittings

These items are used to create in-view connections using press ticks or similar devices.

To connect, you need to calibrate the item, removing the fez with it, after which the sleeve is put on it and the fitting is inserted. The sleeve is captured by the press clamp, after which the handle information is tightly clamped.

Such an element can be used only once, however mounted with fastenings are quite sealed and reliable, so that they are suitable for hidden wiring.

Installation of pipes from different types of materials

For the connection of the elements, one of which is made of metal, and the second - from the metal plastic, the special fittings are intended, one end of which is equipped with a thread, and the second is a socket.

For installation, the metal pipe must be chopped by carvings, clean the palauls, lubricate with soap or silicone, and then throw the fitting with your hand. After the second end is connected to the plastic element, the thread is tightened completely using the key.

Assortment of Fittings of Different Forms

For easy installation, the connecting elements may have a different form. Most often found:

adapters for connecting pipes with different diameters;
tees, providing branches from the central pipe;
corners to change the flow direction;
equipment (installation knee);
crosses, allowing to organize different flow directions for 4 pipes.

A special configuration (couplings, triangles, tees) may have press fittings.
