Plastic pipes for many years are considered a natural choice in the event of replacing the old or installing a new sewage system. Modern production is constantly improving the technology of manufacturing plastic construction products.
As a result, a wide range of high-quality materials of various forms and diameters, which caused progress in the device of reliable, durable sewer pipelines.
Pipe sewer outdoor - diameters.
Pipes for external flow are characterized by orange. Depending on the amount of wastewater produce diameters 110, 125, 160, 200, 250, 300, 400 and 500 mm. The wall size starts from 3 mm, the length varies from 1.2 to 3 m. For the arrangement of urban sewer systems, a diameter of 200 mm is used.
Dimensions of internal PVC pipes.
For the arrangement of internal sewage uses of gray pipes. Standard diameter dimensions are 32, 40, 50, 75, 110 and 160 mm. The wall thickness is not designed for high load, varies from 1 to 3.2 mm. Length can be 0.3, 0.5, 1, 1.5, 2 and 3 meters.
Putting PVC pipe and main characteristics.
The scope of application of this material depends on its physical properties. It will not hurt to find out that polyvinyl chloride is one of the representatives of a group of thermoplastics, which, after heat treatment, and even during mechanical impacts, retain their shape and integrity.
In the process of pipe production, ethylene, stabilized chlorine and additives for improving properties are also used. The main purpose of PVC pipes is to use them in the sewage system. Depending on which their thickness is determined by the scope of use and, accordingly, the view.
It may be:
- internal sewage:
- outdoor;
- pressure system;
- safety drain.
This classification refers to those models that have passed the appropriate processing. Not plasticized PVC-U polyvinyl chloride possesses the best technical characteristics. Operational properties are directly dependent on the technical characteristics.
As for PVC pipes, they are characteristic of such indicators:
- high level of mechanical strength, moreover, three-layer manufacturing technology and outdoor corrugation makes it deeply;
- resistance to the negative impact of the aggressive environment;
- the perfectly smooth wall from the inside, which prevents the delay of solid elements;
- the large value of the internal pressure, at least 6 bar, and maximum 16;
- the highest temperature of wastewater, which is allowed is +65 degrees Celsius, and minimal -10 degrees. There are models withstanding +90 degrees, but if it happens briefly;
- specific weight of 2 kg per pattern meter (the indicator varies depending on the thickness and diameter);
- the strength limit is 50 MPa, and the service life is about 50 years.
Dimensions of pipes for internal and external systems.
PVC sizes are determined by several parameters: diameter, wall thickness and length. For each type of sewerage there are its recommended norms.
Since polyvinyl chloride pipes are manufactured according to GOST, they have strictly defined dimensional characteristics.
The table shows the standard sizes of PVC pipes for internal and external sewage:
- DN - the outer diameter of the pipe,
- d - internal diameter,
- DY - averaged lumen indicator,
- b - wall thickness.
For construction standards, each element of the water supply system has its own requirements for the diameter of the pipes (according to the inner diameter):
- 25 mm - washing machines, dishwashers,
- 30-47 mm - sink in the bathroom, bidet,
- 38-50 mm - kitchen cabin, bath or shower,
- 50 mm - wiring of the sewer system inside the building,
- 70-86 mm - various taps from the central riser,
- 100-118 mm - toilet, central riser,
- 150-190 mm - a plot from the central riser to the city sewer system,
- 200 mm - drainage from bath (sauna),
- 240-300 mm - Pool Decreation
- 300-1100 mm - city sewer highways.

The advantages of PVC material.
It is important to understand that PVC, water supply, for wiring and sewer, have a massive competitive advantage, main of which are considered:
- An impressive service life, the duration of which is usually at least half a century;
- No need to serve an object mounted from PVC;
- The minimum mass greatly facilitates not only storage and transportation, but also installation work;
- Low, in comparison with analogs made from other raw materials, cost;
- The inability to clog the structure due to the smooth internal structure of the part;
- Simplicity and the possibility of quickly performing installation work.
The technical features of the goods under consideration are such that, for their assembly, the use of complex tools and expensive labor is not required: all actions, the execution of which involves the situation (in some cases, even digging tranches for external sewage) may be performed by the connection of the pipes by the termination It is a complex process and special skills does not require.
The Following Two Tabs Change Content Below.
Sewerage is susceptible to wear and with time needs to be replaced. Polyvinyl chloride products The plumbing market has shown themselves from the positive side and in the near future, outdated cast iron equipment will be supplanted.
Types of PVC pipes
Polyvinyl chloride is an innovative material used for the manufacture of pipes and fitting products. Used when conducting internal and external sewage, samotane plum, pressure communications, etc.
When laying sewage mains based on the manufacturers recommendations: PVC products for the internal sewage is solely gray, and for external arrangement - orange.
Sewer pipes and fittings
The use of polyvinyl chloride products for indoors and a wide range of fittings allow you to create high-configuration lines. Their strength and reliability will cope with loads arising in pipeline networks. However, this type is categorically not applicable to use outdoors as not sufficiently hard.
External polyvinyl chloride pipes are unacceptable to use inside the house, since they are unstable to elevated temperatures. The scope of their operation is outdoor communication highways. The diameter of pipes is 100-150 mm makes it possible to drain the unobistants from different buildings. The wall thickness is the main factor responsible for strength and durability.
Regarding the section of the use of PVC sewer pipes are divided into:
- SN-2 is a lightweight option, operated on segments with low loads, in particular, in residential areas and when laying household communications systems in the room.
- SN-4 is a compacted option, used when laying sewage highways under roads, where moderate transport load is observed;
- SN-8 is a high-profile version for urban sewers and for localities with an increased level of traffic.
Types of sewer fittings When assembling PVC sewers, the shaped products occupy an important place:
- crosses and tees used for wiring;
- turn signals, at the expense of which the direction changes;
- gearboxes intended for connecting different in the diameter of sewer pipes made from PVC;
- nozzles - reduce the effect of linear expansion on communications;
- couplings, plugs, revisions, clamps, etc.
It should be considered: the fewer the bends, the more economical installation, while the design will be more practical.
Important! With its own pipeline laying, the price will take shape not only from the cost of the main material, but also auxiliary elements, and it is much higher than the price of PVC pipe.
Advantages and disadvantages of PVC products
PVC equipment has a number of advantages in comparison with metallic:
- not subject to corrosion;
- it has smooth walls that prevent the formation of precipitation;
- does not carry out electricity;
- is not the source of the appearance of harmful substances;
- susceptible to temperature differences;
- long service life;
- easy assembly and installation;
- democratic price.
As with any other equipment, polyvinyl chloride systems have weaknesses:
- PVC products used at temperatures below 15 ° C need heat insulation;
- low thermal conductivity;
- it is not recommended to use PVC pipes in places where the operating temperature is above 60 ° C;
- the presence of damage reduces the service life and stability resistance.
Warming of sewage Important! PVC pipes located in the apartment do not need insulating coverage. With the external laying of communications, you need to warm and isolate the pipeline.

Important! By purchasing PVC pipe for sewage, it is worth requesting a quality certificate for comparing the claimed and real value values.
Polyvinyl chloride pipe
A huge variety of PVC pipes often puts the buyer in a predicable position, thereby complicating the choice. Before the acquisition, it is necessary to carefully examine the technical and physical properties of the product and determine under what conditions it will be applied.
Terms of application - Strength. On the extended areas of the pipeline may have a sagging. This phenomenon may occur when PVC pipes for sewage with low density are used. In such situations, special brackets are recommended.
- Terms of application. The time of using sewage can be reduced in cases where the operating conditions are violated; For example, when aggressive particles appear in the pipeline.
- The length of the highway. Before designing the sewer, it is necessary to make accurate measurements in accordance with the linear characteristics of PVC pipes, it is better to use solid on straight long sections.
- Diameter. On segments of the sewer highway, pipes of a particular section are used. So, for draining the bathroom, products with a diameter of 50 mm are used, and when docking to the central riser is 100 mm.
PVC pipes are reliable and practical, so the plumbing market is leading in the market. Before conducting sewage, it is necessary to carefully examine specifications and requirements for operating conditions, the observance of which is capable of increasing service life.
Did you ever think about a great demand for sewer pipes from polyvinyl chloride?
The thing is that they are easy to install, comfortable in operation and most importantly - inexpensive.
The modern market offers a large range of materials with which the sewage can be equipped.
And in order to make the right choice, you need to own at least minimal knowledge about their characteristics.
PVC pipe appointment and main characteristics
The scope of application of this material depends on its physical properties. It will not hurt to find out that polyvinyl chloride is one of the representatives of a group of thermoplastics, which, after heat treatment, and even during mechanical impacts, retain their shape and integrity. In the process of pipe production, ethylene, stabilized chlorine and additives for improving properties are also used.
The main purpose of PVC pipes is to use them in the sewage system. Depending on which their thickness is determined by the scope of use and, accordingly, the view. It may be:

Features of diameter and size pipe for sewage
Diameter of sewer pipe PVC
D - the outer diameter of the pipe; DY - the inner diameter of the pipe; DR is the outer diameter of the socket; Lp - the length of the Rabbab; L is the length of the pipe without the termination; L1 \u003d L + LP
Diameter of sewer pipe PVC It is the main parameter when choosing them, and it does not depend on whether the waste system is internal or outdoor. It is worth noting that the different size of the pipes means that they are intended for various tasks. Do not forget that the sewage system will be easy and correct if it is competently pick up the sizes.
According to the table, a pipe with a diameter of 40 mm should be used to drain from the bath under a slope of 1.3 cm, further:
- shower - diameter 40 mm, slope 1.48 cm;
- toilet bowl - 100 mm / 1.2 cm;
- sink - 40 mm / 1.12 cm;
- bidet - 30-40 mm / 1.2 cm;
- washing - 30-40 mm / 1.36 cm;
- combined drain - 50 mm / 1.8 cm;
- central riser - 100 mm;
- taps from the riser - 65-75 mm.
The pipeline parameters refers:
- external diameter;
- inner diameter;
- conditional passage - means an internal section;
- nominal cross section.
Table of sizes of sewer pipe PVC
It will help to understand what the sizes of the sewer pipes of the PVC table are available. It is possible below:
Size of sewer pipes PVC - Table 1
The sizes of pipes for external sewage are not regulated in any way, the only recommendation is that its diameter should not give up the size of the circumference of the outer highway. For example, in private homes, pipes 110-250 mm in diameter can be used, and in the intensive load systems even more (about 400 mm).
Sizes of sewer pipe PVC - Table 2
The thickness of the material has considerable importance in operation, it depends on the class of stiffness to which the pipe belongs. If we talk about the thickness of the walls, then there are no specific standards for the sewage setting of internal type, but it is not desirable to use pipes thinner with a thinner of 1.8 mm.
How to choose the optimal diameter of sewer pipes?
Of course, the presence of PVC pipes of different sizes can be considered an advantage, but for those who faced them for the first time, certain difficulties may occur when choosing. To avoid misunderstandings, it is important to know that:
- the diameter of the horizontal pipe cannot be less than the riser through which wastewater pass. This may cause blockages;
- horizontal connections are mounted only with the help of slaughter tees and corners, it is prevented excessive clogging;
- in mandatory, an audit must be installed on each turn, which is a special hole for cleaning. In high-rise buildings, they are installed every 3rd. Even if the plot is long (more than 12 m) and deaf, still does not interfere with the revision;
- the optimal slope of the sewer pipe is 1.2 cm;
- cutting not too wide hollow items are quite simple with a hacksaw or a grinder.
How to choose a diameter? If you use the pipe to remove the dishwasher or washing machine, then its circle must be 25 mm, and if it is a siphon or shower, then 32 mm. On average, sewage pipes mounted inside the apartment must be 40-50 mm. For the street used hollow items of round sections with a diameter of 160-200 mm.
Methods for connecting pipes from PVC depending on their diameter
If the pipe circle does not exceed 63 mm, then the following connection technologies are allowed for their compound:
- popular welding - the principle is in the room of a smaller size in one that is greater;
- coupling welding - an additional part is used in the form of a coupling.
Some models provide threaded compounds, and to use them, fittings are required.
In the case of pipes more than 63 mm in diameter, the method of welding is used. It does not need any couplings, however, the reliability of the connection is not inferior to similar methods.
Until now, not all users understand the difference between the designations of pipe diameters.
- D - the outer diameter of the pipe. This size is required for selection of sockets, couplings, corners, threaded compounds and other mounting and connecting plumbing reinforcements. It is he who is indicated on the labeling, will blow on it to focus during the compilation of the list of elements of the sewer system.
- d - the inner diameter of the pipe. The dimensions of the internal shut-off automatic and semi-automatic valves are binding to it, the rate of movement of fluid flows is calculated. The thickness of the walls of sewage pipes is determined by the difference between external and internal diameters. The inner diameter can be calculated by the formula D \u003d D - 2S. S - wall thickness.
- D U is a conditional passage. The value is used mainly by experts, for ordinary consumers this parameter is not determining, many not heard about it at all.
The drainage systems of modern polymeric materials have a huge advantage over outdated cast iron and steel structures. Apart from the fact that the most diverse sizes of sewer pipes PVC are presented, these products are distinguished by excellent technical specifications. Polyvinyl chloride pipes have a small weight, with them it is easy to operate, polymer plastic is resistant to mechanical effects, chemically active liquids, fungus and mold. Of course, the durability, reliability and affordable cost of PVC sanitary pipes for sewage, the dimensions of which allow you to create systems of any size and complexity have been durable. But, in order to spend this work quickly and high quality, you need to know which performance inherent in plastic sewer pipes.
Purpose of Polyvinyl Chloride Pipes
The dimensions of plastic sewer tubes are quite varied in order to transport a wide variety of fluids inside the house and beyond the end point, which can be a general waste collection system, a collector or septic tank. Despite the fact that this product looks almost the same, its purpose cannot vary quite significantly depending on the model.
So, regardless of the size, PVC sewer pipes have such a classification by strength:
- Heavy. Products have reinforced thick walls, withstanding the most extreme pressure, both outside and from the inside. Used for laying pipelines under the roads, on the territory of industrial and other objects with intensive traffic.
- Middle. Heathe the load from light soil and movement of passenger cars. Have a fairly wide range of use in pressure and non-pressure systems.
- Lungs. Internal sewers, storm and drainage systems are created from the pipes of this class. Under the ground is stacked exclusively in places with a pedestrian movement, since they do not have a sufficient margin of strength. For the most part used to improve the domestic sewage of the non-per-first type.
With the help of plastic pipes of different sizes, external and internal sewer structures, pressure and sampling systems of waste, storm and melt waters are created. When choosing sewer pipes, PVC should be taken into account that the size and color of the products differ. So, sections and fittings for internal works are gray. PVC pipes for external sewage sizes have more impressive. Products of this row have a bright orange color. Regardless of the type and size, plastic sewer pipes perfectly coincide in all respects.
Dimensions of plastic pipes
On a note: The efficiency and practicality of the flow system directly depends on the sizes of PVC pipes for the sewage, which were used for their assembly.
It does not mean at all that it is necessary to apply the largest products. This approach is incredible, as it leads to excessive waste of money, forces and living space in the room. Everywhere you need to pick up a gold middle.
Standard sizes of plastic sewage pipes are divided into such indicators:
- Length. The most common sections are 300 cm long. They are most suitable for the repair and construction of houses with a height of ceilings 240-280 cm. Waste is practically no remaining. To improve non-standard premises, you can purchase sections 50, 100, 150 and 200 cm sections. This avoids excessive costs and unnecessary work associated with a splitting on the workpiece and folding seats.
- Outside diameter. This value is indicated on the outside of the products. It is taken into account when designing a building and arrangement of external sewage, as the initial data for the manufacture of strokes in the walls, depth and width of the trench. As a rule, it uses parts with a diameter of 50 mm and 100 mm to arrange apartments and houses.
- Inner diameter. This indicator determines the bandwidth of the system. It is measured in square centimeters or millimeters.
- Wall thickness. This indicator determines the strength of the structure. It directly depends on the class of product rigidity. The wall thickness varies in the range of 1.8-6 mm. For internal systems of sufficiently thinner pipes. When arranging an external highway, it is worth selecting products with a maximum wall thickness for a guaranteed opposition to the pressure of the soil.
When purchasing sections, it is necessary to acquire fittings of the respective parameters. To avoid unwanted discrepancies in size, it is advisable to buy a set of details from one manufacturer. The goods must be taken with a reserve up to 15% at the calculation on trimming and possible errors.
