GOST for PVC pipes for external sewerage. Roughs and fittings made of unplasticized polyvinyl chloride for internal sewerage systems

Sewage, along with electricity, heating, cold and hot water supply, is one of the main engineering networks that ensure the improvement of residential, industrial and public buildings, as well as the surrounding areas. At the heart of every system for the disposal of domestic, industrial and surface wastewater are networks of sewer pipes. They are made from materials such as:

• steel;
• cast iron;
• concrete;
• ceramics;
• asbestos cement;
• polymers – PVC, HDPE, LDPE.

Each of the listed materials has its own advantages, but in their totality, sewer pipes made of PVC and other polymers are beyond competition. They appeared much later than other types of these products, but quickly gained recognition among all categories of developers. In new sewerage networks, PVC sewer pipes are increasingly used for internal and external sewerage.

Advantages of PVC sewer pipes

When choosing materials for installing utility networks, special attention is paid to their advantages, which make it possible to obtain the best result with a relatively small investment of time, effort and money. In this sense, PVC pipes for sewage have undoubted advantages:

• PVC is a chemically inert material, which provides it with high resistance to aggressive liquids and external influences;
• such products have minimal weight compared to analogues made from other materials, which allows installation of PVC sewer pipes without the use of heavy special equipment;
• the range of polymer pipes is fully compatible with products for similar purposes made of steel, cast iron, concrete, etc., which allows connection to existing drainage networks;
• the full range of these products includes plumbing pipes and PVC adapters for sewerage: couplings, tees, regular and saddle bends, plugs, adapters for assembling a drainage system;
• the inner surface of polymer pipes does not accumulate deposits, which minimizes the risk of blockages;
• Networks made of plastic pipes withstand ground movements well without compromising the tightness of the connections.

The characteristics of PVC pipes for sewerage guarantee them a long service life - at least 50 years under the most severe operating conditions. The main disadvantages of such products are the inability to use them in pressure networks and low resistance to heat. The temperature of the wastewater for them should not exceed 45 °C.

PVC pipes for external drainage systems

The production of PVC sewer pipes is regulated by two regulatory documents. In order of product numbering, the first are PVC pipes for sewerage in accordance with GOST 32412-2013 for internal drainage systems from buildings. The document came into force at the beginning of 2015; it sets out all the requirements that these products must meet, including their range. We have summarized the dimensions of PVC pipes for sewerage and their other main characteristics in the following table:

All sizes of PVC sewer pipes for internal sewerage, except for the effective length, are regulated by GOST 32412-2013. The length of products is determined by the manufacturer, himself or in agreement with the customer of the product. If you look at the photo in the sewer pipe catalog, you can easily identify products for internal networks. They are grey. Standardized characteristics also include diameter, wall thickness and length of sockets, but product labeling indicates only the diameter and wall thickness of pipes.

In addition to two technical characteristics, the product designation indicates the trademark and/or name of the manufacturer, as well as the month and year of manufacture. The summary table of sizes of PVC sewer pipes we have provided is compiled on the basis of GOST 32412-2013, but in it this information is scattered throughout the text of the document.

Speaking about the length of sewer pipes, we should remember about pressure PVC pipes in accordance with GOST R 51613-2000 for transporting liquids and gases. This is a closely related product and has pipe length requirements. The value of this indicator is 4–12 m and changes in increments of 0.25 m. Manufacturers of sewer pipes most often adhere to the same rules, but they also produce pipes less than four meters long.

PVC pipes for external sewerage and surface drains

The consumer should know that orange PVC sewer pipes are intended for external drainage networks. Orange and brown-orange colors for them are specified in GOST 32413-2013. This equally applies to the gray color of PVC pipes for internal sewerage, which is recommended in GOST 32412-2013. Different colors provide easy product identification.

Both GOSTs were prepared and put into effect at the same time. They are very similar to each other, including having an identical structure. PVC sewer pipes in accordance with GOST 32413-2013 differ not only in color. We have collected their characteristics in a summary table:

All sizes of PVC sewer pipes according to the catalog can be found in the GOST standards mentioned here. The first column of both tables with product types gives a hint on how to connect PVC sewer pipes to each other. For this, glue, special couplings for straight pipes and the elastic properties of O-rings are used.

Please note that PVC sewer pipes 110 mm in diameter are the initial standard size for external networks. Pipes of smaller diameters are used for internal sewage systems. External and internal pipes of the corresponding standard sizes are fully compatible with each other.

Fittings for drainage networks made of PVC pipes

To install drainage systems, in addition to pipes, fittings are required to assemble individual elements into a single network. The range of shaped products is presented in GOST 32412-2013 and GOST 32413-2013. It includes:

• bends with bend angles of 15, 30, 45, 67.5 and 87.5–90 degrees; the range of bends to internal networks additionally includes products with an angle of 22.5°;
• sliding and socket couplings;
• adapters from larger to smaller diameter pipes;
• regular and transition type tees with third side connection angles of 45, 67.5 and 87.5–90 degrees;
• saddle bends and plugs for external sewerage pipes.

Shaped parts are manufactured for socket and push-in connections, including in various combinations. For example, an external PVC sewer pipe with a diameter of 200 mm of the socket type can be connected to a straight product, including a larger or smaller one. The marking of fittings indicates their main characteristics:

• for a conventional tee – nominal diameter and connection angle;
• for adapters and transition-type tees - all connecting dimensions and connection angle;
• for shaped products to external networks, the pipe class designation is added to the marking, for example SDR 41, as well as the name of the part (coupling, tee, etc.).

The methods of applying markings to pipes and fittings for them are identical - relief embossing or printing with indelible paint. A certificate for PVC sewer pipes confirms that they are made from raw materials of appropriate quality and have been tested upon acceptance for tightness, impact strength and other parameters.

Other types of PVC pipes for drainage

The latest polymer product to enter the market is corrugated PVC pipe for sewerage. It is manufactured according to GOST R 54475-2011. Corrugation, or structured wall, can be circular, spiral and longitudinal, with hollow and solid ribs (sections), with smooth outer and inner surfaces (type A), with a corrugated top (type B).

Corrugated pipes are intended for non-pressure external sewerage networks. Their range includes pipes of the DN/ID series with a diameter of 100 – 2,400 mm and DN/OD – 110 – 1,200 mm. The range of pipes includes products of classes SN 2, SN 4, SN 8 and SN 16. Products of the heaviest class allow the installation of sewerage at a depth of up to 50 m underground. The corrugation enhances the pipes’ resistance to transporting liquids heated to 79 °C.

Plumbing parts made of plastic have been used by people since the middle of the last century. The first plumbing fixtures were used for water supply, and soon enough they began to be used for sewerage.

At what pressure can such spare parts operate?

Today, PVC pressure pipes are produced in the following pressure groups:

• PN 6;
• PN 10;
• PN 16;

The information presented indicates that the assortment in question is capable of withstanding pressure from 0.6 to 1.6 MPa.

What are the main benefits?

The most significant positive features of such components traditionally include:

• Excellent quality and high resistance to various types of destructive influences;
• Maximum performance of the assembled system;
• Excellent hydraulic performance;
• Light weight;
• An impressive service life, which remains unattainable for analogues made from other materials;
• Possibility of combining components from different materials in the context of one design;
• Possibility of installation without the involvement of complex and experienced installers;

Areas with a diameter of 40 and 110 mm are traditionally used indoors. 40mm products are used to connect washing machines, washbasins and bidets, but 110 mm pipes are used to connect toilets.

What does the gray color of the part indicate?

The color indicates the area of ​​direct application. The most common options are gray and orange. The gray part is for indoor use; its technical parameters (temperature conditions, optimal pressure, range of diameters) fully correspond to the scope of application. They are also oriented for outdoor use, their parameters fully correspond to this.

Individual parameters of Pragma products.

This standard prescribes the following features of such parts:

• Scope of application;
• Permissible deviations of geometric parameters;
• Product type (with or without socket);
• Type (for regular or adhesive joints);
• Other options;

It is well known that the optimal pipe diameter depends on what plumbing unit will be connected through it and what load it will create. Thus, pipes of small diameter (usually 40 - 50 mm) are used to connect washbasins, dishwashers, washing machines or bathrooms. PVC pressure pipes with a diameter of 110 mm are used to connect toilets.

What are the temperature characteristics of the products in question?

During the use of the systems, as a rule, extreme temperatures do not arise and the characteristics of the pipes are appropriate. The maximum that such a structure can withstand for a long time is + 60 degrees, which is quite enough if we take into account the specifics of sewerage operation. The minimum harmless temperature is 10 degrees, which also turns out to be quite enough in practice.


Such pipes are called bell-shaped based on the type of their connection. The good thing about the socket method is that its application does not require complex tools, including soldering irons. Pipes are simply done manually. Cutting parts in accordance with the existing pipeline diagram will also not cause trouble and will not take much time: the corresponding manipulations are performed using a regular hacksaw.

It is worth noting that the products in question are usually used in multi-storey buildings, since it is in such buildings that, as a rule, pumping equipment is used that creates pressure (pressure), which dictates the need to use pressure pipes. Often such parts are used to pump out accumulated masses from a septic tank or cesspool. The walls of such pipes are traditionally thicker than those of gravity taxes. This feature dictated by the fact that the product in question must be prepared for a sharp decrease in pressure and at the same time must not suffer damage that would make further operation of the system impossible.

Another important feature of the range under consideration is the durability of the pipes. Relatively recently, one could only dream of installing pipes and forgetting about their existence for many 50, or even 100 years, but with the advent of PVC, the situation has changed dramatically, and the warranty period for such components is measured in tens of years, while being so reliable and functional details remain democratic and accessible.

GOST pipes for sewerage

The use of polyvinyl chloride in the production of plastic pipes has made a real revolution in plumbing work, which is carried out on a private and industrial scale. According to GOST requirements, PVC pipes for sewerage are intended for transporting domestic and industrial wastewater to household septic tanks or central highways. At the same time, there are a number of requirements both for the products themselves and for the conditions of their operation. Only if they are followed, pipelines can last 50 years or more, without maintenance, replacement or repair.

Rough for toilet includes three different types pipes Additionally, the waste line should be vented with a 2-inch pipe that vents to the outside. The configuration of these pipes depends on the location of the toilet in relation to the pre-existing plumbing and the construction of the house.

Place the toilet drain in a location in the bathroom that will provide sufficient clearance for the toilet when installed; 12 inches from the back wall is suitable for most toilets. Cut a 3- or 4-inch hole for the crawl space drain using a reciprocating saw. The size of the hole depends on what size pipe you plan to use. A 3-inch line provides the best drainage, but if the distance to the post stack is more than 6 feet, a 4-inch pipe is required.

Specifications

GOST PVC sewer pipes sets a number of parameters for these products that are necessary for the safe and trouble-free operation of structures assembled from them. In addition, the main technical characteristics of plastic sewer pipes must comply with current construction and sanitary standards and regulations.

Insert a flat flange of the appropriate diameter into the hole in the bathroom and screw it to the base using a screwdriver. The flange holds the toilet to the floor and forms a connection between the toilet and the waste line. The elbow should be pointed in the direction of the soil stack.

Cut into a stack and tape into a 4-inch plumbing tee with a 3 or 4-inch opening, depending on the size of the waste line. Glue the waste line to the tee. Reduce the hole size of the top of the soil stack to 2 inches using a reduction sleeve. This pipe discharges the toilet and should end 1 foot above the roof line.

GOST PVC sewer pipes defines the following criteria for these products:

1. Place of use. Products are divided into internal and external. According to GOST, polyvinyl chloride pipes for internal sewage systems are painted gray and are used to collect and drain wastewater from premises. According to GOST, PVC pipes for external sewerage are painted orange and can be located underground or on the surface. External type products are used to create storm, collector and drainage systems.
2. Outdoor conditions. According to this classification, PVC products are divided into pressure, non-pressure and corrugated. According to GOST, free-flow PVC pipes for sewerage can be installed only in those places where liquids will be transported by gravity at a relatively low speed. Pressure systems are designed to be subject to fairly strong internal and external pressure, which can be ± 10 atmospheres. Corrugated sections are intended for laying highways in curved sections. They can be manufactured in both pressure and non-pressure versions.
3. Hardness class. According to GOST, PVC pipes for sewerage have 3 classes of hardness (light, medium, heavy). This allows the use of polymer products in a wide variety of conditions, from a riser in a multi-story building to a highway laid under a road or construction site. This information marked on all pipes as a standard marking.
4. Dimensions. These indicators directly affect the assembly order and throughput of systems. According to GOST 1898-2001, PVC sewer pipes must have a certain length, wall thickness, weight, internal and external diameter. Thus, the length of the sections varies between 50-300 cm, the outer diameter of the internal and external lines is 100-110 mm and 110-250 mm, respectively. The wall thickness of the products is 2.2-3.6 mm.
5. Connection method. According to GOST, plastic sewer pipes are joined in sockets or welded. Welding is used to join sections and fittings of external pressure systems. The socket connection is used when assembling non-pressure risers. To create reliable joints, sealing collars and sealants are used.

On a note: Provided that GOST plastic sewer pipes fully comply with the declared parameters, the result of the assembly work will be structures with ideal performance.

Section of internal pipes

Select an existing copper pipe that carries cold water near the toilet and turn off the water to that pipe. It should run from the tee to the wall behind the toilet and extend about 2 inches beyond the wall under the tank. Solder all the seams after you have assembled the power line and attach the line to a stud in the wall behind the toilet using a clamp.

Stop the water supply line from shut-off valve. You can solder the valve to the pipes or install the valve using a compression fitting. Make sure the valve is closed before turning on the water. If you are connecting a new toilet to an existing stack, you only need to install waste and supply lines. A configuration in which the waste line connects directly to the sewer will require ventilation for the waste line. You can tie the vent pipe to an existing one that already runs through the roof. The valve pipes should either slope upward away from the toilet or be horizontal. To achieve this, the toilet must be located within 10 feet of the stack. . Pipes for household sewer systems are made from unplasticized polyvinyl chloride with the addition of stabilizers and additives intended for the disposal of all types of wastewater in residential and industrial buildings, as well as for the removal of sediments inside and outside buildings.

Advantages of plastic waste systems

PVC pipes for sewerage that comply with GOST have an extensive list of very significant advantages:

1. Durability. Unlike metal analogues, polymer systems do not corrode. This means that they are not at risk of thinning and loss of integrity. There is no need to paint or treat rust on the outer surface of the line.
2. Light weight. This factor directly affects the cost of construction and repairs. The products do not add additional weight to the building, which allows saving on the foundation and walls. In addition, even sections with a diameter of 250 mm can be worked manually without the use of lifting equipment.
3. Smooth inner surface. Dirt and lime deposits do not settle on it. Even abrasive particles pass through the drain system without delay or friction.
4. Elasticity. GOST pipes allow bending of the pipeline under the influence of external factors, such as soil heaving or shrinkage of buildings. Thanks to this, the pipeline maintains functionality and tightness.
5. Biological and chemical inertness. Mold and mildew do not form on polymer plastic. The material is resistant to acids, alkalis, solvents and other aggressive substances. This allows you to install PVC sewer pipes that comply with GOST at enterprises, factories and workshops.
6. Environmental and Fire safety. Even when hot water is passed through, the waste system does not emit harmful substances. PVC does not support combustion. The chlorine component causes the polymer to attenuate in the absence of a flame.

Separately, it is worth dwelling on the cost of the material. It is several times lower than that of steel products. This determines the high popularity of plastic pipes that meet GOST requirements.

Types of drainage systems

The pipes have a service life of more than 50 years. The pipes are not suitable for the disposal of wastewater containing high levels of gasoline, acetone and benzene. The connections are made using a socket fitting and a rubber ring, ensuring complete sealing of the joints.

How much do sewer pipes cost?

Ideal for pipelines installed underground or above ground laid on free flat surfaces for the removal of wastewater and sludge. Pipes for domestic sewer systems are made using a fitting. The useful length of a pipe with a female fitting is the length without the length of the muffler.

Thanks to the integrated gates, the installation of pipes and connecting elements for domestic sewerage is very simple and quick. Editor's Note: The following is the first in a two-part series examining the various methods available today for restoring sanitary sewer systems.

Sewage sewer systems consist of sewer pipes and sewer structures such as manholes, inlet and outlet structures, and pumping stations. Sewer pipes are made of various materials such as clay, concrete, reinforced concrete, cast iron, ductile iron, polyvinyl chloride and polyethylene. Most manholes are primarily made of clay bricks or reinforced concrete.

Preface

The goals, basic principles and basic procedure for carrying out work on interstate standardization are established in GOST 1.0-92 “Interstate standardization system. Basic provisions" and GOST 1.2-2009 "Interstate standardization system. Interstate standards, rules, recommendations for interstate standardization. Rules for development, acceptance, updating and cancellation"

As a result of physical, chemical, and biological phenomena, several components of sanitary sewer collection systems for major cities have suffered defects such as collapsed pipes, cracked pipes, dislodged joints, and cracked manholes. This results in surcharges or overflows from wells located upstream of pipe segments that are exceeded in capacity. The total flow also often exceeds throughput treatment facilities wastewater, resulting in bypasses of untreated wastewater into receiving waters.

This shunt can cause harm to human health and the environment. The destruction of excavations led to trenchless technology. The traditional method of rehabilitating defective sanitary drains and associated fixtures is excavation and replacement. Since sewer pipes in urbanized areas are mostly located in the middle of streets, excavation and replacement creates traffic disruptions that result in lost productive time for workers in such areas. In addition to the costs associated with lost production time for workers, additional costs are incurred when repairing excavated roads and other structures.

2 INTRODUCED by the Technical Committee for Standardization TC 465 “Construction”

3 ADOPTED by the Interstate Council for Standardization, Metrology and Certification (Protocol No. 44-2013 of November 14, 2013)

4 By order of the Federal Agency for Technical Regulation and Metrology of December 30, 2013 Ne 2382-st, the interstate standard GOST 32412-2013 was put into effect as a national standard Russian Federation from January 01, 2015

In an attempt to reduce the costs and disruptions associated with excavation and replacement, the spa remediation industry has developed "no-dig" technologies for rehabilitating sanitary sewer systems. Rehabilitation of hatches is carried out in several ways. Several technologies are used to restore defective hatches. Some of the most common techniques include spraying the inside surface of the defective manhole using urethane resin, epoxy or cementitious materials; installation of epoxy resin cladding based on cured resin; and installing a fiber grass liner.

5 This standard is in accordance with the international standard ISO 3633:2002 Plastics piping systems for soil and waste discharge (low and high temperature) inside buildings - Unplasticized poly(vinyl chloride) (PVC-U) high temperature) inside buildings - Unplasticized polyvinyl chloride (PVC-U) and European standard EN 1329-1:1999 Plastics piping systems for soil and waste discharge (low and high temperature) within the building structure - Unplasticized poly(vinyl chloride) (PVC-U) - Part 1: Specifications for pipes, fittings and the system (Plastics pipelines for the discharge of wastewater (low and high temperature) inside buildings - Unplasticized polyvinyl chloride (PVC-U) - Part 1: Specifications on pipes, fittings and system).

Sprayed urethane resin is probably the most effective material for restoring defective manholes. The first step is to conduct a system survey. Trenchless technologies have been implemented in the United States with varying degrees of success. To determine the most suitable products To rehabilitate any sanitary sewer collection system, each community must conduct a sanitary sewer survey.

It should be noted that trenchless technologies have not completely replaced the excavation and replacement of defective sewers and manholes. There are still circumstances in which excavation and replacement is the best method for rehabilitating a segment of a sanitary sewer system.

Our sewer pipes are the best for water supply systems and are also used in water supply and heating technology to expand existing sanitary facilities. Sewer pipes and other forms can be installed to install water to expand the existing pipe network.

The nominal width of the drainpipe has a standard diameter. Multilayer pipe - we learn from nature. This allows the production of a product whose wall is similar to the structure of bone, as known from the animal kingdom. Material. The result is pipe tubes and moldings with a perfectly smooth inner wall that is abrasion resistant and an elastic core that can withstand both ground pressure and traffic loads. Sealing elements Sealing of connections is ensured by sealing elements made of stable elastomers.

PIPES AND FITTINGS MADE FROM UNPLASTIFIED POLYVINYL CHLORIDE FOR INTERNAL SEWAGE SYSTEMS

They are mounted on a flute. The sealing properties are maintained even when the pipe is deformed or deflected. The connection of pipes is very simple due to the sleeve with a sealing element. This results in fewer connections than elements made from heavy materials. In the event of a supply shortage, we reserve the right to supply equivalent products from other brand manufacturers. Discover more articles from the field at reasonable prices in our category. Only one shipping fee will be charged per order.

1 area of ​​use

This standard applies to pipes and fittings made of unplasticized PVC-U polyvinyl chloride (UPVC) with a solid wall intended for sewer systems for the removal of domestic wastewater and storm drainage systems inside buildings.

The photo shows: foam pipes can split when low temperatures. What is clearly recognized in the so-called “balance test” also brings significant disadvantages and dangers for the publisher in practice. The plug-in system consists of many precisely matched parts and is permanently sealed and extremely durable. Regardless of whether the channel is a street or a home, the system has a lifetime for many generations.

The three-layer polypropylene pipeline system is characterized by high annular and longitudinal rigidity. The white inner layer makes it easy to inspect with a camera and is rigid. The outer layer makes the tube stable. Single-layer polypropylene tubes are available in two stiffness classes. They are equipped with a double rosette with a fixed O-ring. The system is completed with an extensive molding program.

2 Normative references

This standard uses normative references to the following interstate standards:

** GOST R ISO 3126-2007 is in force on the territory of the Russian Federation.

3.5 average outside diameter d, m, mm: The measured outer circumference of a pipe or pipe end of a fitting in any cross section, divided by l (i=3.142), rounded up to the nearest 0.1 mm.

The connection is usually made using electric welding. Alternative installation methods such as plowing, flushing or bursting require special requirements for the pipe system. For example, they are particularly resistant to point loads and surface damage.

Ensure water supply even during drought

The extensive shaft program allows for inspection, cleaning and ventilation of pipelines, as well as pipe assembly. Each child is promoted and receives an education suited to his or her needs and aptitudes. The wear and tear on these tanks and the high maintenance costs that many people want to keep pose a danger to everyone. Natural wear and tear on these pipes is caused by cotton roots in many places - the pipes leak and there is a risk that the waste water will not drain properly and thus become a health hazard.

3.6 average internal diameter of the socket d im, mm: Arithmetic mean of measurements of the internal diameter of the socket in one cross section.

3.7 ovality: The difference between the measured maximum and minimum outer diameters in the same cross-section of a pipe or pipe end of a fitting.

3.8 wall thickness e, mm: The result of measuring the wall thickness at any point along the circumference of the product.

3.9 average wall thickness e t, mm: The arithmetic mean of several wall thickness measurements at points uniformly distributed around the circumference in one cross-section of the product, including the measured minimum and maximum wall thickness in the same cross-section.

GOST pipes for sewerage

The use of polyvinyl chloride in the production of plastic pipes has made a real revolution in plumbing work, which is carried out in private and industrial settings. According to GOST requirements, PVC pipes for sewerage are intended for transporting domestic and industrial wastewater to household septic tanks or central highways. At the same time, there are a number of requirements both for the products themselves and for the conditions of their operation. Only if they are followed, pipelines can last 50 years or more, without maintenance, replacement or repair.

Specifications

GOST PVC sewer pipes sets a number of parameters for these products that are necessary for the safe and trouble-free operation of structures assembled from them. In addition, the main specifications plastic sewer pipes must comply with current construction, sanitary standards and regulations.

GOST PVC sewer pipes defines the following criteria for these products:

1. Place of use. Products are divided into internal and external. According to GOST, polyvinyl chloride pipes for internal sewage systems are painted gray and are used to collect and drain wastewater from premises. According to GOST, PVC pipes for external sewerage are painted orange and can be located underground or on the surface. External type products are used to create storm, collector and drainage systems.
2. Outdoor conditions. According to this classification, PVC products are divided into pressure, non-pressure and corrugated. According to GOST, free-flow PVC pipes for sewerage can be installed only in those places where liquids will be transported by gravity at a relatively low speed. Pressure systems are designed to be subject to fairly strong internal and external pressure, which can be ± 10 atmospheres. Corrugated sections are intended for laying highways in curved sections. They can be manufactured in both pressure and non-pressure versions.
3. Hardness class. According to GOST, PVC pipes for sewerage have 3 classes of hardness (light, medium, heavy). This allows the use of polymer products in a wide variety of conditions, from a riser in a multi-story building to a highway laid under a road or construction site. This information is printed on all pipes as standard markings.
4. Dimensions. These indicators directly affect the assembly order and throughput of systems. According to GOST 1898-2001, PVC sewer pipes must have a certain length, wall thickness, weight, internal and external diameter. Thus, the length of the sections varies between 50-300 cm, the outer diameter of the internal and external lines is 100-110 mm and 110-250 mm, respectively. The wall thickness of the products is 2.2-3.6 mm.
5. Connection method. According to GOST, plastic sewer pipes are joined in sockets or welded. Welding is used to join sections and fittings of external pressure systems. The socket connection is used when assembling non-pressure risers. To create reliable joints, sealing collars and sealants are used.

On a note: Provided that GOST plastic sewer pipes fully comply with the declared parameters, the result of the assembly work will be structures with ideal performance.

Advantages of plastic waste systems

PVC pipes for sewerage that comply with GOST have an extensive list of very significant advantages:

1. Durability. Unlike metal analogues, polymer systems do not corrode. This means that they are not at risk of thinning and loss of integrity. There is no need to paint or treat rust on the outer surface of the line.
2. Light weight. This factor directly affects the cost of construction and repairs. The products do not add additional weight to the building, which allows saving on the foundation and walls. In addition, even sections with a diameter of 250 mm can be worked manually without the use of lifting equipment.
3. Smooth inner surface. Dirt and lime deposits do not settle on it. Even abrasive particles pass through the drain system without delay or friction.
4. Elasticity. GOST pipes allow bending of the pipeline under the influence of external factors, such as soil heaving or shrinkage of buildings. Thanks to this, the pipeline maintains functionality and tightness.
5. Biological and chemical inertness. Mold and mildew do not form on polymer plastic. The material is resistant to acids, alkalis, solvents and other aggressive substances. This allows you to install PVC sewer pipes that comply with GOST at enterprises, factories and workshops.
6. Environmental and fire safety. Even when hot water is passed through, the waste system does not emit harmful substances. PVC does not support combustion. The chlorine component causes the polymer to attenuate in the absence of a flame.

Separately, it is worth dwelling on the cost of the material. It is several times lower than that of steel products. This determines the high popularity of plastic pipes that meet GOST requirements.
