PVC sewer pipes: specifications and installation. PVC pipes for outdoor sewerage: classification L,N,S, types of connections

PVC pipes are mainly used for sewerage. Polymer pipes are used for laying sewer lines for a number of reasons. Initially, it should be noted that PVC pipes have such properties as ease of installation, availability and high performance. Sewer PVC pipes in this regard make the best use of all the advantages of this type of pipe.

Deciding where exactly certain varieties will be used polymer pipes determined by their technical properties. To understand the basics, you should understand the origin of this type of material.

PVC or polyvinyl chloride belongs to a group of thermoplastic materials that retain their shape even after physical impact on them, the pipes are pre-treated at high temperature.

PVC is based on stabilized chlorine and polyvinyl, and some manufacturers prefer to add a number of elements that have a significant impact on specifications material.

Polyvinyl chloride pipes are intended for the creation of sewer-type highways. All PVC pipes are divided into 4 large types:

  • Pipes for holding internal system sewer lines;
  • Pipes for the device of an external sewer line;
  • Pipes for the device of the pressure system;
  • PVC pipes for gravity drainage systems

The dimensions of PVC sewer pipes, depending on the scope of application, vary significantly. For example, polyvinyl pipes for gravity drainage systems have the largest dimensions, which corresponds to GOST used throughout Russia.

Also, PVC pipes vary in diameter and weight. The diameter of PVC pipes affects their mechanical characteristics.

The above classification makes it possible to evaluate the diversity of the functionality of polyvinyl pipes. Dimensions must also be taken into account because their throughput depends on the size of the pipes.

For outdoor sewerage

Rigid pipes with a thick wall are used to carry out the external line.
They may differ in the type of construction:

  • Single layer. This type of pipe resembles outwardly pipes for an internal highway. But they have an orange color and more stringent indicators;
  • Three-layer pipes (corrugated). They have a protective layer in the form of a corrugation. It has high mechanical strength The soft layer inside has a low friction index.

For the external line, pipes with a diameter of 110-630 mm are used.

For internal sewerage

When developing a project for the internal sewerage of a building, special polyvinyl pipes are used. This category of pipes is used for the internal pipeline, because the rigidity of the products is incredibly light.
Internal pipes, characteristics:

  • Connection - socket;
  • The walls are smooth;
  • The following diameters are especially popular: 40,100 and 32mm;
  • The main sewer pipe can be either 300 or 3000 mm.

Assortment of types of PVC sewer pipes

Today, a huge variety of different PVC pipes is produced. These products differ in many indicators, one of which is the diameter of the pipe:

  • sewer pipe PVC 32 mm and PVC 50 mm - this category of pipes is most often used to create an internal sewer line;
  • PVC sewer pipe 100 mm and 110 mm are intended not only for creating a sewer system, but also for internal drains;
  • sewer pipe PVC 160 has an orange color used to create an external main sewage system, wall width - 3.6 mm;
  • PVC sewer pipes GOST 1898 2001 - due to high quality and availability, this type of PVC pipe is the most popular among Russians;

According to external indicators:

  • gray PVC sewer pipes are used for internal sewage;
  • orange PVC sewer pipes - for an external sewer line;

PVC-U pressure sewer pipes have serious technical characteristics, they are used in sewerage places where forced disposal of sewage is used.

Mounting

The installation of the sewer system should be carried out only with the participation of specialists.
You can connect PVC sewer pipes:

  • Glue way. This method is performed using glue and special fisting. Before cutting through the pipes, the chamfer must be removed. Treat the cut with glue and fix the seam with clamps.
  • With the help of a flare. It is mounted using silicone by installing a socket in a pipe with a large diameter.

Elements

In order to mount the sewer system, do not forget about the following elements:

  • PVC sewer pipe adapters should be slightly thicker and stronger than the main pipe material;
  • PVC tees for sewer pipes are used to create a complex sewer line;
  • fittings for PVC sewer pipes have high thermal conductivity, are used both for connecting pipes and for drainage systems;
  • sealant for PVC sewer pipes can be purchased at any plumbing store;
  • glue for PVC sewer pipes must have special setting properties.

The price of sewer PVC pipes

The price of sewer PVC pipes varies from 15 rubles to 1500 rubles. Their cost directly depends on the technical characteristics and on the destination. Also, the type of purchase can affect the cost of PVC pipes: wholesale or retail. When buying in bulk, the price of some types of pipes can drop to 10-12 rubles.

Video

It is very important that the sewer line is made of quality materials, otherwise, in which case you will have to do overhaul the entire building and re-pipe the sewer.

Reading 5 min.

Any owner of an apartment that is undergoing renovation wants finishing materials and furniture to meet all the required quality standards. Therefore, the choice of goods for repair is determined not only by the fact how this thing fits the necessary parameters, but also whether it meets the requirements of GOST.

A certificate of conformity is available for all products that are produced in compliance with the necessary requirements. Therefore, on the packaging of a particular material for finishing work, there is always information about the manufacturer and compliance with standards.

Regulatory documents and production

The certificate for sewer PVC pipes is issued by the Federal Agency for Technical Regulation and Metrology. The document has its own number and expiration date. It indicates the certification body, the name of the product, as well as information on compliance with the requirements of regulatory documents.

The completeness of information is ensured by the presence on the certificate of the name of the manufacturer of the goods. In addition, it is written who issued the certificate and on the basis of what tests. If additional information was used during certification, it is indicated in the annexes.

The certificate is signed by the head of the body that issues it, and the expert who checked the goods. Nearby there is always a round seal of the body that carried out the certification.

There is also a list of GOSTs that set standards for the production and use of PVC products. Among them:

  • GOST 51613 2000 - describes the technical characteristics of PVC products;
  • GOST 18599 2001 - sets standards for the size of sewer pipes;
  • GOST 52134 2003 - regulates the process of manufacturing PVC products;
  • GOST 1898 2001 - describes the requirements for sewerage in cottages, apartment buildings.

Certificates for products are issued after testing in laboratory conditions. In order to obtain it, the manufacturer submits an application for certification. The application goes for consideration to an accredited body or certification center for this area. After that, the necessary laboratory tests are carried out.

One of the most common sizes of PVC pipes are those with a state standard: 110 mm, 50 mm and 52 mm.

The fastest and least expensive is the method of manufacturing PVC products by extrusion. First, granulated polyvinyl chloride is heated to a plastic state. Then, using a special device, the plastic is shaped. After calibrating the product in a vacuum chamber, it is sent for cooling. With the help of a special device, marking is applied, and the product is equipped with a rubber ring seal.

Material properties

PVC (or polyvinyl chloride) is a thermoplastic synthetic material. Externally, it is a white powder.

This material has the following characteristics:

  • high strength;
  • poor heat resistance;
  • insoluble in water;
  • good dielectric properties;
  • resistant to alcohols, acids, mineral oils, alkalis.

It is possible to dissolve or swell PVC using the following agents:

  • ketones;
  • chlorinated and aromatic hydrocarbons;
  • ethers.

Despite the different diameters of the pipes, they can be connected using adapters. The connection is achieved using seals and couplings.

An important point is the rapid cooling of plastic pipes, so it is necessary to provide them with the necessary thermal insulation.

Proper installation of sewerage will allow you to use it for more than 50 years, which means that you will save cash. Installation of sewerage can be carried out independently, if you first familiarize yourself with the standards of plumbing work.

Sewer PVC pipes with certificates must have all of the above properties.

Characteristics of PVC pipes for internal and external sewerage

When choosing products for sewerage, all attention is paid to the wall thickness. It is necessary to use sufficiently strong pipes that will withstand all external influences. The main parameters when choosing a product are wall thickness and inner diameter.

Smooth-walled gray PVC products are used for internal sewage. PVC inner pipes of the following sizes are common:

  • in diameter - 110, 50, 40, 32 mm;
  • length - 315 to 3,000 mm.

The thickness of these pipes is not less than 1.8 mm. Products are connected through a socket. The outer tubes are yellow and orange and have thicker walls. For example, for light conditions of rigidity, the wall thickness is from 3.9 mm, for medium conditions - 4.9 mm, for heavy conditions - 5.9 mm.

Products used for external and internal sewerage must have a certificate from the sanitary and epidemiological service.

Corrugated PVC pipes

PVC pipes are used not only for sewage. To ensure the insulation of electrical wires and cables and protect them from mechanical damage and impact environment, use corrugated PVC pipes.

These pipes have a division according to the type of strength:

  • light;
  • heavy;
  • superheavy;
  • construction.

They are used for:

  • electrical networks (at voltage up to 1,000 V);
  • telephone, computer, IT networks and communications;
  • fire-resistant cable lines;
  • protection of pipes used in the construction of a warm floor.

Ensures compliance with GOST 1898 PVC standards.

What are the temperature characteristics of the products in question

The minimum temperature for the operation of pipes is -10 ° C, the maximum - + 60 ° C. PVC products for sewerage can withstand a wide range of temperatures. Practice shows that emergency situations do not arise during the operation of products.

At what pressure can PVC products work

The sewer pipe can have a different pressure group (PN 6, PN 10, PN 16). The pipe external for the external sewerage is capable to maintain pressure to 10 atmospheres.

Expert opinion on the results of the sanitary and epidemiological examination

Compliance of the product with the established norms of the "Uniform sanitary-epidemiological and hygienic requirements for goods subject to sanitary-epidemiological supervision (control)" reveals an expert opinion based on the results of a sanitary-epidemiological examination.

Test tests for PVC products (such as PVC pipes for internal sewage) are carried out separately. At the final stage of testing, the expert evaluates the protocols and makes a decision. In case of a positive decision, a certificate is issued.

Plastic pipes and fittings for them for internal sewage systems are manufactured according to GOST 22689.0-77 - GOST 22689.20-77 high density polyethylene (HDPE), low density polyethylene (LDPE), polypropylene (PP) and unplasticized polyvinyl chloride (PVC).
The maximum temperature of permanent drains for HDPE and HDPE pipes is 60°C, for PP pipes 70°C, for PVC pipes 50°C.
Pipes are connected using rubber sealing rings, gluing, using a union nut and a rubber gasket, as well as welding.
Sockets and smooth ends of fittings are produced in four types (GOST 22689.2-77):
I - for joining PVC, PVP and PP products with a rubber sealing ring or by gluing (PVC only);
II - for connecting products made of HDPE, PNP and PP contact
socket-butt welding;
III - for connecting products from HDPE, HDPE and PP using a union nut and a rubber gasket;
IV - for connecting products from HDPE, HDPE and PP using a coupling with an electrospiral insert or flash butt welding (PVP only).
The sizes of sockets and smooth ends of fittings of types I - IV are given in table. 46-48.
Pipes by GOST 22689.3-77 they are made in the form of straight segments, and at the request of the consumer with sockets and with smooth ends prepared for connection (Table 49), as well as in the form of nodes connected to fittings, floor risers and wiring.
The sockets of PVC pipes are molded, and from PVP, PNP and PP they are obtained by welding nozzles to pipes according to GOST 22689.4-77 or couplings according to GOST 22689.13-77. Flares and spigots must match GOST 22689.2-77. At the smooth ends of pipes connected according to type I with a rubber sealing ring along 22689.19-77 (Tables 50 and 51), mounting marks are applied.

Table 60

Plumbing parts made of plastic have been used by people since the middle of the last century. The first plumbing was used for plumbing, soon enough they began to be used for sewage.

At what pressure can these parts work?

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

  • PN 6;
  • PN 10;
  • PN 16;

The information presented indicates that the assortment under consideration is able to withstand 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 performance resistance to various kinds of destructive influences;
  • Maximum performance of the assembled system;
  • Excellent hydraulic performance;
  • Small weight;
  • An impressive period of use, which remains unattainable for analogues made from other materials;
  • The possibility of combining in the context of one design components from different materials;
  • The possibility of installation without the involvement of complex and experienced installers;

Plots 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 say?


Color indicates the scope of direct application. The most common options are gray and orange. The gray part is for indoor use, its technical parameters (temperature regime, optimum pressure, diameter range) fully correspond to the scope of application. are oriented for outdoor use, their parameters are fully consistent with this.

Individual parameters of Pragma products.

This standard prescribes the following features of such parts:

  • Scope of application;
  • Permissible deviations of geometric parameters;
  • Type of product (with or without a socket);
  • Type (under normal or under adhesive connection);
  • Other options;

It is well known that the optimal diameter of the pipe depends on which plumbing unit will be connected through it and what load it will create. So, 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 toilet bowls.

What are the temperature characteristics of the products in question?

During the use of systems, as a rule, extreme temperatures do not occur and the characteristics of the pipes are appropriate. The maximum that such a design 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 socket pipes based on the type of their connection. The bell-shaped method is good because, as part of its application, there is no need for complex tools, including soldering irons. Pipes are simply in manual mode. Cutting parts in accordance with the existing pipeline scheme will also not cause trouble and will not take much time: the corresponding manipulations are performed using a conventional 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 also used to pump out accumulated masses from a septic tank or cesspool. The walls of such pipes are traditionally thicker than those of non-pressure taxes. This feature It is dictated by the fact that the product in question must be ready for a sharp decrease in pressure and, at the same time, must not receive damage that would make further operation of the system impossible.

Another important feature of the range under consideration is the durability of pipes. Relatively recently, one could only dream of installing pipes and forgetting about their existence for a long 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 remains affordable and accessible.

How easy it is to join sewer pipes, see the video for tips on laying sewers:

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 volumes. According to the requirements of GOST, PVC pipes for sewerage are designed to transport domestic and industrial wastewater to domestic 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 observed, pipelines can last 50 years or more, without maintenance, replacement and repair.

Rough toilet includes three different types pipes. In addition, the waste line must be vented with a 2-inch pipe that extends to the outside. The configuration of these pipes depends on the location of the toilet in relation to the pre-existing plumbing and building of the house.

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

Specifications

GOST PVC sewer pipes sets a number of parameters for this product that are necessary for the safe and trouble-free operation of structures assembled from it. In addition, the main technical characteristics of plastic sewer pipes must comply with current building, 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 the connection between the toilet and the waste line. The elbow should point in the direction of the pile of soil.

Cut into a stack and stick into a 4" plumbing tee with a 3" or 4" hole, 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 with a reduction sleeve. This pipe releases the toilet and should end 1 foot above the roofline.

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 sewerage are painted gray and are used to collect and discharge wastewater from premises. According to GOST, PVC pipes for external sewerage are painted orange, they can be located underground and on the surface. Products of the external type are used to create storm, collector and drainage systems.
  2. conditions of the external environment. According to this classification, PVC products are divided into pressure, non-pressure and corrugated. According to GOST, non-pressure PVC pipes for sewerage can only be installed 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 on curved sections. They can be manufactured in both pressure and non-pressure versions.
  3. Rigidity class. According to GOST, PVC pipes for sewerage have 3 stiffness classes (light, medium, heavy). This allows the use of polymer products in a wide variety of conditions, from a riser in a multi-storey building to a highway laid under a road or construction site. This information is applied on all pipes in the form of a standard marking.
  4. Dimensions. These metrics directly affect the build order and system throughput. According to GOST 1898-2001, PVC sewer pipes must have a certain length, wall thickness, weight, inner and outer diameter. So, the length of the sections varies within 50-300 cm, the outer diameter of the internal and external highways 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. A socket connection is used when assembling non-pressure risers. To create reliable joints, sealing cuffs and sealants are used.

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

Cross 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 behind 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 with a zip tie.

Shut off the water supply line with a shut-off valve. You can solder the valve to the pipes or install the valve with 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 the 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 link ventilation pipe with the existing one, which already passes through the roof. The valve pipes must either slope upward from the toilet or be horizontal. To do this, the toilet must be located within 10 feet of the stack. . Pipes for domestic sewer systems are made of 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.

Benefits of plastic waste systems

The corresponding GOST PVC pipes for sewerage have an extensive list of very significant advantages:

  1. Durability. Unlike metal counterparts, polymer systems do not corrode. This means that they are not threatened with thinning and loss of integrity. The outer surface of the highway does not need to be painted and treated against rust.
  2. Light weight. This factor directly affects the cost of construction and repair. Products do not weigh down the weight of the building, which saves on the foundation and walls. In addition, even with sections with a diameter of 250 mm, you can work manually without the involvement 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 main line under the influence of external factors, such as heaving of the soil or shrinkage of buildings. Thanks to this, the pipeline retains functionality and tightness.
  5. Biological and chemical inertness. Mold and fungus 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 corresponding to GOST at enterprises, factories and workshops.
  6. Ecological and fire safety. Even when passing hot water, the sewage system does not emit harmful substances. PVC does not support combustion. The chlorine component causes the polymer to decay 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 causes the high popularity of plastic pipes that meet the requirements of GOST.

Varieties of drainage systems

Pipes have a service life of more than 50 years. The pipes are not suitable for wastewater with a high content of gasoline, acetone and benzene. Connections are made using a female fitting and a rubber ring, which ensures complete tightness of the joints.

How much do sewer pipes cost?

Ideal for pipelines installed underground or on the surface of the earth, laid on free flat surfaces, for the removal of sewage and sediments. Pipes for domestic sewer systems are produced using a fitting. The useful length of a pipe with a female fitting is its length without the length of the muffler.

Thanks to the integrated gate, the installation of domestic sewer pipes and fittings is very simple and fast. Editor's Note: The following is the first in a two-part series on the various methods available today for rehabilitating sanitary sewer systems.

Sewer systems sewer systems consist of sewer pipes and sewer structures such as manholes, inlet and outlet structures, and pumping stations. Sewer pipes are made from various materials such as clay, concrete, reinforced concrete, cast iron, ductile iron, PVC and polyethylene. Most hatches are mainly made of clay brick or reinforced concrete.

Foreword

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 the development, adoption, updating and cancellation "

As a result of physical, chemical and biological phenomena, some components of sanitary sewer collection systems for major cities suffered defects such as collapsed pipes, cracked pipes, displaced joints, and cracked hatches. This results in surcharges or overflows from wells located upstream of over-capacity pipe segments. The total flow also often exceeds the capacity treatment facilities wastewater, leading to bypasses of raw wastewater into receiving waters.

This shunt can harm human health and the environment. The destruction of the excavations led to trenchless technology. The traditional method of remediating defective sanitary drains and associated supplies is excavation and replacement. Since sewer pipes in urban areas are mostly located in the middle of the streets, excavation and replacement create traffic disruptions, resulting in lost productive time for workers in such areas. In addition to the costs associated with lost production time for workers, additional costs arise from the repair of excavated roads and other structures.

Rehabilitation of manholes is carried out in several ways. Several technologies are used to repair defective hatches. Some of the more common technologies include spraying the inside of a defective hatch using urethane, epoxy, or cementitious materials; installation of epoxy resin cladding based on cured resin; and installing a fiber grass liner.

5 This standard complies with 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

Sprayed urethane resin is probably the most effective material for repairing defective wells. The first step is to conduct a system survey. Trenchless technologies have been implemented in the United States with varying degrees of success. In order to determine the most suitable products for the rehabilitation of any sewer collection system, each community should conduct a 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 way to rehabilitate a segment of the sanitary sewer collection system.

Video about the installation of plastic sewer pipes

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 pipeline network.

The nominal width of the downspout 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 resistant to abrasion and a resilient core that can withstand both ground pressure and traffic loads. Sealing elements Sealing of connections is provided by sealing elements from steady elastomers.

INTERSTATE STANDARD

PIPES AND FITTINGS FROM UNPLASTIFIED POLYVINYL CHLORIDE FOR INTERNAL SEWER SYSTEMS

They are set on a flute. 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 compounds than with elements made of heavy materials. In the event of a shortage of supply, we reserve the right to supply equivalent products from other manufacturers of the brand. Discover in our category more articles from the area at reasonable prices. Only one time shipping cost will be charged per order.

Delivery within Austria. Delivery time in Germany is usually around 1-2 working days, this is indicated for each article and may be longer. Pipes and fittings are supplied with a molded socket and O-ring. Orange color. Fingers from cheap pipes With channel channels, the handle on an inexpensive product can become expensive! The channel pipe must provide a service life of at least 50 years. Styrofoam pipes often fail to achieve this goal. Consequences are high costs because the exchange and new installation cost much more than the product itself.

Unplasticized polyvinylchloride pipes and fittings for waste discharge inside the buildings. _Specifications_

Introduction date -2015-01-01

1 area of ​​use

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

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

The three-layer pipeline system made of polypropylene is characterized by high ring and longitudinal rigidity. White inner layer facilitates inspection with a camera, hard. The outer layer makes the tube stable. Single-layer polypropylene tubes are available in two stiffness classes. They are equipped with a double socket with a fixed sealing ring. The system is completed by an extensive molding program.

2 Normative references

This standard uses normative references to the following interstate standards:

** On the territory of the Russian Federation, GOST R ISO 3126-2007 applies.

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

The connection is usually made by electrical welding. Alternative laying methods such as plowing, flushing or tearing require special requirements for the piping system. For example, they are particularly resistant to point loads and surface damage.

Ensure water supply even in drought

The extensive shaft program allows inspection, cleaning and ventilation of pipelines, as well as pipe assembly. Each child is promoted and receives an education appropriate to his needs and inclinations. The wear and tear on these tanks and the high maintenance that many people want to save is a danger to everyone. The natural wear and tear of these pipes is caused by the roots of the cotton in many places - the pipes leak and there is a risk that the sewage will not drain properly and thus become a health hazard.
