PVC pipes for electrical and sewage in accordance with GOST 51613-2000 and other documents

Polyvinyl chloride (or simply PVC) pipes are the most suitable option for arranging a variety of systems: external or internal sewerage, wiring, etc. This is due to their durability, corrosion and stray currents, resistance to organic and chemical substances, smooth surface inside. On PVC products there are a number of documents regulating their parameters: GOST 51613, 1898 and 52134, adopted from 2000 to 2003.

Overview of GOST PVC pipes

Document 51613 of 2000 extends to pressure products made from unplasticized PVC. They can be used for plumbing, transporting drinking water, the temperature of which is 0-45 ºС, and other liquids, as well as gaseous substances.

Depending on the temperature of the medium, a pressure reduction coefficient is selected: 41-45 ºС - 0.64; 36-40 ºС - 0.70; 31-35 ºС - 0.78; 26-30 ºС - 0.88; up to 25 ºС - 1.00.

Note! GOST does not apply to electrical pipes.

Document 52134 of 2003 includes dimensions and requirements for fittings and pressure pipes from various thermoplastics, including unplasticized and chlorinated PVC. GOST 18599-2001 pipe made according to standard 52134 does not contradict. Such products can be used not only for water supply, but also for heating.

There are separate regulatory documents for PVC pipes for outdoor sewage. GOST 32413 of 2013 regulates the parameters of just such products and shaped elements for them.

Some provisions of GOST 18599

The main characteristics of polyethylene pressure pipes are defined in GOST 1898-2001. PVC sewer pipes also belong to thermoplastics products.

Standard 18599 contains guidelines for the use of pressure pipes made of polyethylene, their main dimensions, parameters, designation and labeling, technical requirements, test conditions and acceptance rules.

Plastic pipes are made of materials PE 63, PE 100, PE 32, PE 80. For each type, the dimensions and marginal deviations of linear parameters are defined in document 18599. The value of the parameter for reducing the working pressure (maximum) at the temperature of the water that is transported through the pipeline to 40 ºС is given in the table.

Table 1

Designation of pipes and fittings according to GOST 52134

All regulatory documents (GOST 51613, 52134, 18599) provide the rules for the symbol of the pipe.It usually includes the abbreviated name of PVC (NPVH 125 or NPVH 100), type of bell, size ratio.

Also, dashes show the numerical values ​​of the wall thickness and the outer diameter. In addition, the pipe has a designation of its purpose:

• household drinking;
• technical.

The designation of fittings from a variety of thermoplastics includes the name of the material of production, the value of the minimum long-term strength increased by 10 times, the size ratio. The dash indicates the nominal diameter (outer) of the pipe and its wall thickness, which will be connected, the class of operation, the nominal pressure, expressed in MPa.

At the end of the product designation is given GOST, according to which they are made.

PVC pipe safety requirements

Pipes made of unplasticized PVC can be assigned to the third hazard class defined in GOST 12.1.005, as well as to the group of slow-burning products (GOST 12.1.044), the ignition temperature of which is not lower than 300 degrees.

During storage and use, such pipes are not able to release toxic substances into the environment. Contact with them does not require the use of personal protective equipment. The safety of the production process must meet the requirements of GOST 12.3.030.

Note! Sanitary standards allow the release of vinyl chloride in water not more than 0.01 mg / l during operation by household drinking pipes from unplasticized PVC.

To prevent atmospheric pollution during production, the requirements of GOST 17.2.3.02 must be met. Before putting into operation pipelines for household and drinking purposes, they are washed with drinking water for more than 2 hours.

Advantages of PVC sewer pipes

GOSTs regulate the basic parameters and characteristics of PVC products. Such communications are the most acceptable option for arranging an external sewer network, since they can last up to half a century at a temperature of no more than 45 ºС. They also have high hygiene and environmental friendliness.

Light weight and a variety of fittings provide convenient transportation and quick installation. The external sewage system is possible due to the resistance of the pipe to ultraviolet radiation, low temperatures and its low combustibility.

When choosing a suitable PVC product, you should pay attention to such parameters as diameters, length and strength class. In addition, it is important to be sure that you comply with GOST PVC pipes for sewage.

There are three groups of stiffness:

1. Heavy (S) withstanding 8 thousand N / m²;
2. Average (N), withstanding 4 thousand N / m²;
3. Light (L), withstanding 2 thousand N / m².

The first class is designated SN-8 and has the possibility of underground laying up to 8 m deep, the second - SN-4 - under areas with low traffic, the third - SN-2 can be located at a shallow depth.

Installation of an external sewage network

PVC pipes, GOSTs on which their parameters are determined, can be used in internal and external sewage networks. For the second option, products according to documents 51613-2000 and 52134 from 2003, equipped with a sealing ring and a bell, are suitable.

The laying of PVC pipes of the external network starts from the foundation. The place of entry of the part into the bell is lubricated, and it is inserted into it until it stops. The pipeline is insulated with a special heat-insulating material.

Note! When laying, a slope of 0.02 m per meter of the length of the PVC pipe is observed.

Revision wells are mounted every 15 meters.At the final stages, the slope of the system is checked and it is sprinkled in layers by sand, which is slightly compacted on the sides. Next, the trench is filled with soil. The entire sewage pipeline is laid to a septic tank or sewage well.

PVC internal drainage

The internal sewer system is designed to remove wastewater from residential premises and buildings. It consists of pipes, branch lines, outlets and risers. For this reason, installation work is carried out at the construction stage.

Such sewage system is used for continuous or short-term operation. During installation, bonding and socket connection are used. Mounting clamps prevent slipping during installation. It is necessary to observe such distances when fixing the elements:

• one or two meters for vertical lines;
• 10 diameters of communications for horizontal sections;
• between sewer pipes and walls - at least 4 mm.

The use of two turns of 45 degrees rather than one of 90 turns will help to reduce the noise level. It is also important to prevent burrs at the ends of the products after cutting, since the presence of roughness and protrusions contributes to the accumulation of unwanted deposits in such places and the formation of blockages.

Corrugated Electrical PVC Pipes

Key documents for PVC pipe for electrical wiring - GOSTs. Such products are manufactured according to GOST 51613, their installation is determined by GOST 30244.

Note! Corrugated products are intended for laying electrical wiring in floors, ceilings, walls and in open form in storage and industrial premises.

Structurally, such communications have 2 layers - external corrugated and internal - extremely smooth. Due to such a structure, they have significant ring stiffness, a good degree of protection during thermal or mechanical impacts, and increased flexibility.

Reinforced corrugated products are made of a spiral frame, which is filled with soft polyvinyl chloride. They are most often used to connect control panels to power panels and to combine process equipment operating with increased vibrations.

Parameters of PVC Corrugated Pipe

GOST 14254 regulates the degree of protection that electrical pipes must provide. Corrugated PVC products meet all the requirements of this document. They are made of a material characterized by self-extinguishing ability.

Installation can be carried out at temperatures of -5 - +60 degrees. To facilitate the placement of the wiring cable inside the pipe, the latter can be equipped with a broach. Heavy products have increased strength and can be laid under a cement screed. Corrugated pipes are packed in bays of 100, 50, 25, 20 and 15 meters, which can be stored for up to two years.

Such products make it possible to mount the system in a space with limited volume, which does not allow the use of boxes and rigid parts, and are also able to withstand voltages of up to 1 kV.

Various documents for electrotechnical corrugated polyvinyl chloride pipes (GOSTs, TU) determine their diameters (0.16-0.63 (* 10² ) mm), color (white or gray) and marking (T - heavy, L - light, 1 - with broach, 0 - without broach).

Elements for mounting wiring with PVC pipes

GOSTs determine the characteristics of products, the diversity of which allows for quality installation. Rigid and corrugated PVC tubes are installed using many non-combustible elements. These include:

• coupling (for joining pipes inside or outside rooms with high humidity);
• elbow or elbow (for joining parts at right angles);
• box (to ensure connection with junction boxes);
• tee (to provide a T-shaped union of rigid elements);
• fastenings with a collar (for installation of tubes on a wall);
• corrugated sleeve (either gray or transparent);
• latch holders.

The use of all these additional elements ensures high tightness of the system. If the tube is equipped with a broach, then it is necessary to have a bite during cutting.

Note! It is important to monitor the wire (broach) so that it does not slip into the pipe.

When installing a harness consisting of several wires, they must be fastened and connected to the broach end. When choosing a suitable corrugated product, it is important to precisely determine the diameter and take into account that the catalogs give the external value of this parameter for the pipe.

Installation of PVC corrugated pipes

GOSTs and other regulatory documents govern not only the characteristics and features of products, but also the rules for their use. When installing electrical wiring, it is important that all requirements are met.

The initial stage of work is to draw up a wiring diagram that would preclude pipe crossing, and marking. If you want to ensure only mechanical protection of the wires, you can limit yourself to installing an unpressurized pipeline. In other cases, it must be dustproof and waterproof. Also, pipes must be placed below the coolant to avoid undesired heating of the cable.

When the diameter of the corrugated product is 0.16 * 10² mm fastening is done through 300-400 mm. On average, there are 3 mounting clips per meter of pipe.
