PVC sewer pipes. PVC pipes for sewerage: sizes and prices of plastic products Pipelines for internal sewerage from PVC pipes

This article discusses in detail the features of products such as PVC pipes for sewerage: the dimensions and prices of plastic elements and additional components used to install a drainage system. In the text you can find the classification of pipes, their advantages and disadvantages, as well as an overview of the catalogs offered hardware stores. This information can be used to select and purchase PVC products in order to install sewers.

Sewerage is constructed on the basis of pipes, which are an integral part of the system. During operation, these elements are subjected to static and dynamic loads, therefore, the choice of products should be approached thoroughly and attention should be paid to technical characteristics.

PVC products are widely used for arranging both internal and external sewage systems. Among others polymer products they are considered the most popular and in demand. These plastic items cylindrical shape are made on the basis of polyvinylchloride thermoplastic. This material has one advantageous property, due to which PVC pipes acquire improved characteristics. The fact is that the polyvinyl chloride thermoplastic after heat treatment and extrusion procedure keeps its shape well.

According to GOST 51613-2000, non-pressure PVC pipes for sewerage are tested for impact strength using the Charpy system. The maximum allowable number of elements that are subject to destruction should not exceed 10%.

Note! A slight change in the length of the elements after heating is allowed, but not more than 5%.

GOST also defines standard sizes plastic pipes for sewerage and limit deviations from the parameters that are allowed in quality products. Polyvinyl chloride contains two components in its composition - stabilized chlorine and ethylene. In order to improve performance, manufacturers add various additives to thermoplastic mixtures. As a result, under the influence high pressure a composite joint with a high margin of safety is obtained.

Why is it profitable to buy PVC pipes for sewerage

Polymer products have many advantages. Manufacturers endowed plastic pipes light weight, while maintaining enough high level strength. The cost is affordable for most buyers, so consumers prefer this particular type of product.

Among the most important advantages are also beneficial performance characteristics. The inner walls of polymer pipes have a smooth surface with a slight presence of longitudinal stripes and waviness, so the likelihood of blockages caused by the accumulation of fecal fractions or growths is extremely low. Plastic is not subject to corrosion and is resistant to aggressive environments.

For the construction of a pressure sewer, PVC pipes are ideal. Moreover, the installation of the system can be performed with my own hands. This does not require the use of special equipment. Available in a wide variety of sizes and mounting elements, which greatly simplifies the design and installation of piping.

Products intended for laying outdoor sewerage, frost resistance is inherent. The effective service life of pipes made on the basis of polymers exceeds 50 years. If strictly adhere to the requirements assembly technology, the sewer line will not be displaced. Docking nodes often diverge when the level of occurrence changes. ground water. But if there were no violations during the installation process, even under such conditions, the system of polymer pipes remains airtight.

Important! Under the influence of ultraviolet, the performance of pipes decreases. Therefore, it is not recommended to store products in places where they will be exposed to direct sunlight.

Types of plumbing pipes and PVC adapters for sewerage

Range plastic products is very wide, so that consumers can buy plastic pipes for sewerage of any modification and purpose. Taking into account the purpose and operating conditions, three categories of elements for the construction of the highway can be distinguished.

All of them are in full accordance with the main standard sizes. Products with lightweight construction (SN-2), used for laying sewerage in the area pedestrian sidewalk. The scope of their application also extends to recreation areas with green spaces, as well as areas that are not subject to traffic loads.

Pipes with average parameters (SN-4) are laid in areas where there is little traffic. Especially for industrial areas, pipes of heavy type (SN-8) are provided. These products are suitable for the organization of the sewer system in places with high traffic.

In addition to straight pipes for the construction of sewers, connecting elements are used. With their help, you can organize the turns of the line (fittings equipped with a rubber seal). Also, on their basis, toilet bowl connections with sewerage from plastic pipes or joints between other elements are formed.

On sale are the following types adapters:

• couplings for repair maintenance of the network;
• reductions connecting elements with differences in section size;
• tees and crosses for the formation of wiring of several pipes;
• rotary bends;
• expansion pipes for carrying out repair work.

In addition, in stores you can buy plastic sewer hatches in order to carry out an audit. These elements are also used for after-sales service systems when blockages occur.

PVC pipes for sewerage: dimensions and product prices

The most demanded diameter of PVC sewer pipes is 110 mm. Such products are lightweight and do not cause difficulties during installation. Pipes intended for construction outdoor system, can have two-, one- and three-layer structure. The outer layer is made of unplasticized PVC. In three-layer products, the inner layers are made of foam material having a porous structure. It is a recycled product.

The connection of the pipe walls is carried out simultaneously with the help of "hot" technology. The result is a cylindrical product with a monolithic structure. Due to the cavities that are formed between the walls, it is possible to reduce the weight of the pipe.

Classification of products according to the class of ring stiffness:

1. L - light products that are laid to a depth of 80-200 cm.
2. N - pipes of medium hardness, designed for installation at a depth of 2-6 m.
3. S - rigid products with a large wall thickness that can withstand loads at a depth of up to 8 m.

Useful advice! For the organization of the external system, it is recommended to use two-layer pipes with a corrugated structure. Due to the presence of stiffeners with outside increases the strength of products.

Ring stiffness is marked with the abbreviation SN. Technical specifications pressure pipes and elements for systems where the movement of wastewater is carried out by gravity are completely different. In each case, the sewage system is subjected to different loads: head pressure or the influence of gravity. For this reason, the prices of pressure-type sewer plastic pipes are much higher than those of elements for gravity systems.

Pressure type pipes are presented in three variations, capable of coping with pressure effects of 10, 6 and 12.5 kg per cm².

Dimensions and prices of plastic pipes for sewerage: external system

For the construction of sewerage of external and internal types, products of different sections are used.

Typical dimensions of the diameter of plastic pipes for sewerage:

• 110 mm - minimum size sections for pipes for outdoor use, used to divert wastewater in summer cottages;
• 315 mm - products with such a cross section are intended for the construction of a common sewer system serving several houses;
• 630 mm - pipes with maximum size sections for the construction of a highway capable of serving a small village.

In addition, to work with external system you will need to buy a hose for pumping sewage, made of polyvinyl chloride.

Fecal hose prices:

Pipes for external sewerage are manufactured in orange color, so they cannot be confused with other product options. Cylindrical elements can have different lengths. The most popular segments are 0.5, 1 and 2 m. There are other variations, for example, 3 m and 6 m. Some manufacturers have an extended range of sizes. They offer individual elements 12 cm long.

The price of PVC sewer pipes for domestic sewage

Pipes intended for arrangement internal system taps are made in gray color. They have a low price, since these products are characterized by a light stiffness class and are completely unsuitable for outdoor work. The most popular PVC pipes for sewerage are 50 mm in diameter. Although there are other cross-sectional sizes on sale - 32, 40 and 110 mm.

The inner walls of the gray pipes are smooth. The elements are connected to each other using the "bell" technology. The length varies in the range from 25 cm to 3 m, although non-standard sizes are also found.

Note! A branch connecting plumbing with vertical pipe, should correspond to the diameter of the riser. The use of a section of a smaller size is not allowed.

For the construction of a drainage system in the bathroom, it is recommended to use pipes with a cross section of 75 mm. They are suitable for connecting a shower enclosure, bidet and washbasin with public sewerage. They are characterized by a high throughput.

For domestic drains, products with a diameter of 50 mm will suffice. They are lightweight, flexible and resistant to high temperatures(hot water) and influence chemical substances(in case of cleaning the system by chemical means). To connect the toilet, it is better to take products with a section size of 100-110 mm. They will withstand strong pressure, because they have a special resistance.

Catalog of fittings for PVC sewerage and prices for products

The fittings are used in systems where the effluent temperature does not exceed 80ºC. The products also withstand short-term discharge of waste fluid at temperatures up to 95ºC.

In this case, stock means:

1. Dirty water from the toilet.
2. Waste fluid from the shower and sink.
3. Chemical compositions with a pH level in the range of 2-12.

For internal sewerage the following details apply:

• couplings (with stop, full bore for repair);
• reduction;
• revisions with cover;
• tees (with an angle of 90, 67, 45º);

Do-it-yourself recommendations for installing sewerage from plastic pipes

The sewer system in old buildings was predominantly made of cast iron. Despite the practicality of this material, sooner or later it needs to be replaced. For the construction of modern risers, more durable and lightweight materials are used.

Useful advice! When replacing the pipeline, it is possible to organize ventilation, which was absent in old-type systems. Thus, it will be possible to eliminate unpleasant sewer odors that can penetrate the room.

Experts even recommend abandoning the use of galvanized and, the period of which is no more than 10 years, and giving preference to polyvinyl chloride or polypropylene products. The shelf life of elements made of polymers is 30-50 years.

To dismantle the old sewer, you will need the following tools:

• screwdrivers big size to get small parts out of the system;
• grinders with a disk for metal;
• plastic film to cover the cut pipe opening;
• nail puller and chisel;
• funds personal protection(glasses, gloves, apron);
• hammer and perforator;
• scrap and grinder.

How to make the transition from a cast-iron pipe to a plastic sewer: dismantling the old system

First you need to designate the necessary indents. The first mark is placed at a distance of 10 cm from the ceiling level, and the second - at a distance of 80 cm from the tee. In the marked areas, it is necessary to make cuts with the help of a grinder, with a depth of half the pipe section. A chisel should be attached to the upper file and hit with a hammer.

A similar procedure must be performed from below. Force must be applied to the blow with a hammer so that the cast-iron pipe splits, and its middle part can be removed.
The section of pipe coming from the ceiling must be covered with plastic wrap.

The lower part of the system consists of a tee and other connecting elements. To dismantle it, you will need a crowbar or a nail puller. These tools are necessary in order to loosen the fixation zones. When this is done, you can remove the . In some cases, you can not do without the use of a perforator. It allows you to remove the cement that fixes the fasteners.

It is allowed to use a screwdriver or a chisel, with which you can chip off the cement. After that, the tee is removed. If it was not possible to complete this procedure, you can use a grinder equipped with a disc designed to work with metal surfaces. In this case, you should step back from the socket by about 3 cm. After dismantling the connections, you should carefully clean the areas of their placement from dirt, and then treat the surface with a grinder.

Useful advice! Before starting work, it is imperative to notify the neighbors, since during the replacement of the pipeline it is impossible to use the bathroom and the bathroom. Otherwise, water from the upper floors will pour into the room and flood the neighbors below. For the same reason, all work must be carried out as quickly as possible.

Installation instructions for sewerage from plastic pipes

For execution installation work You will need the following tools and materials:

• pipes with a section size of 110 mm;
• outlet tee;
• rubber cuffs designed to seal and fix the fasteners between the PVC pipe and the scraps of the cast iron system;
• a branch pipe that provides a transition from a cast-iron pipe to a plastic one and vice versa;
• fastenings for pipes;
• soap to be used as a lubricant to facilitate the installation of fasteners;
• vertical building level.

The process of installing plastic pipes is carried out in a similar way, only in reverse order. Rubber sealing cuffs must be inserted into the sections of cast-iron pipes. The adapter is installed from above, from below it is necessary to mount the tee. The fixation of all elements should be as tight as possible to ensure the tightness of the sewer system. If the tee is loose in the joint, it can be sealed with linen tape or a silicone-based sealant.

Each developer in the process of building a cottage or country house forced to solve the problem associated with the choice of materials for equipping the sewer system. A high-quality and reliable pipeline is necessary even in urban apartments, and even more so in separate objects. As the practice and experience of many specialists in the construction and repair industry shows, sewer pipes PVC for internal sewerage is the best option today.

The installation of pressure and non-pressure PVC pipes is not particularly difficult, since the connection involves the use of socket technology. If we compare the parameters of polybutylene, polyethylene and even metal pipelines, then PVC products are ahead of their competitors in all respects.

PVC pipes

Today, several types of pipes are presented on the pipeline technology market, differing in characteristics and methods of application. Depending on the place of use, they are outdoor or designed for installation in the internal sewerage system.

Outdoor differ big size and diameter. For their production, plastic with high strength characteristics is used. Pipes for outdoor installation are available in orange.

Internal pipes are used to drain wastewater in a private house or apartment. Externally, they can be distinguished by gray plastic.

Ambient conditions and fluid parameters also influence the choice plumbing pipes PVC for sewerage. Depending on these parameters, they are divided into the following types:

1. Non-pressure - used to drain wastewater without forcing pressure (by gravity).
2. Pressure - used in conditions where it is impossible to do without creating additional pressure.
3. Corrugated - characterized by increased flexibility, which allows laying in problem areas.
4. PVC-U pipe - the symbol "H" at the beginning of the marking indicates unplasticized polyvinyl chloride. This material is resistant to aggressive environment due to increased strength, rigidity and density. PVC-U is produced by continuous extrusion. Note that the material is harmless to environment and a person. Products from it have a wide range of applications, ranging from feeding pure water and ending with harmful acids.

GOST sets the dimensions of sewer pipes in the range from 50 to 110 mm. In addition, according to GOST, pipe products PVC must meet a number of requirements, including the following:

• the presence of the necessary markings;
• tests for various operating parameters, including strength;
• correct packaging and transportation;
• connections of sewer mains must be made using socket technology;
• if branching or turning of the system is required, appropriate fittings must be used.

Specifications

PVC pipes can be marked with the letters PVC. The length of commercially available products can reach 6 m. At the same time, they are easily cut to fit any required size, able to withstand pressure up to 16 atm.

In the pipeline of a standard apartment, the average pressure is 4 atm. In the event of a water hammer, this figure can increase to 12 atm. For wiring around the apartment, it is enough to use a pipeline marked PN 6. However, when connecting to a riser, you will have to use a pressure reducer.

The marking indicates the outer diameter, as well as the wall thickness. For example, sewer PVC 110 mm have a wall thickness of 3 or 3.2 mm. It must be remembered that pipes with the same diameter may have different thickness. So their nominal pressure will be different.

Installation of internal sewerage using PVC can be carried out at a temperature range of -5 ... + 90 ° С. At the same time, the maximum working temperature environment should not exceed +50°С. It is desirable that the temperature hot water did not exceed +60°С. It is possible to exceed this condition for a short time, otherwise PVC loses its strength. In addition, PVC is a material that is resistant to mechanical stress.

Advantages and disadvantages

The properties of the PVC material determined its high demand for the arrangement of sewer systems. The main advantages of a PVC pipe in comparison with analogues:

• low cost of the product;
• ease of installation, subsequent repair and disassembly;
• a wide variety of species;
• not susceptible to aggressive environment, high corrosion resistance;
• ability to withstand high pressure;
• resistance to mechanical stress;
• light weight;
• long service life;
• structural rigidity;
• high resistance to linear expansion.

The disadvantages of a PVC pipeline include the above-described limited temperature regime, as well as the fragility of the material. In addition, reactions with organic solvents must not be allowed.

Application of PVC pipes

The scope of plastic inner pipes depends on their diameter. For example, sewer pipes with a diameter of 75 mm are used to equip the bathroom. They can be connected to a shower, washbasin, bidet and other plumbing items.

Their peculiarity lies in the smooth inner walls that prevent the appearance of silt deposits.

It is important to understand that the correct ratio of thickness and diameter of the pipe guarantees maximum throughput.

For wiring sewer network, carrying out the transportation of domestic wastewater, use sockets with a diameter of 50 mm. They are installed when connected to the drains of plumbing fixtures. They are flexible, lightweight and resistant to chemicals.

To connect the toilet to sewer system use a pipe with a diameter of 100 mm. It has the same properties as the previous sockets. In some cases, a product with a diameter of 110 mm is required for connection.

Gray sewer pipe 110x3000 is more used for connecting to an external sewer system and a septic tank for a private house. It is resistant to aggressive soil, not afraid of corrosion and temperature extremes. It has high resistance and can withstand increased pressure. Subject to temperature regime up to 40°C, the service life of the product can reach 50 years.

With the help of fittings, several pipes can be joined at the same time, thereby creating the necessary branching of the internal sewer system.

PVC inner pipe refers to a widespread type building materials, which is extremely popular among the rest. Unique properties and affordable cost allow you to purchase them cheaper, simple and easy to install, and the end result will delight the buyer for many years. Polyvinyl chloride has captivated customers with its extraordinary lightness and thin wall, which allows it to replace many standard metal alloys.

PVC inner pipe should have the following advantages:

• High wear resistance and long service life, which fluctuate up to tens of years.
• High resistance to the aggressive action of strong acids and bases, as well as to mechanical damage.
• Reliability with high lightness source material, which will allow them to be used in various construction, industrial and domestic works.
• Ease of installation and tightness when fastening elements.
• Possibility of simple and efficient maintenance. This allows timely repair work with the replacement of individual pipe lengths or the application of a special fastening sleeve.

The PVC inner pipe must have a high capacity, which is ensured by a smooth wall and a small amount of posture.

Internal PVC sewer pipes

Sewer networks are located both indoors and outside. The first type is called internal network and for its assembly, internal PVC sewer pipes are required, plumbing equipment and fasteners. This network must wastewater to the exit point from the building. Therefore, pipes must be wear-resistant and reliable, which will reduce the number of repairs and extend their life.

PVC internal sewer pipes are produced in various diameters and lengths, which ensures maximum quality installation networks. Their resistant inner surface allows the passage of small particles in the form of sand and other elements, which will not affect their integrity. The temperature limit is 60 degrees, which must be taken into account. Simple installation does not require special skills and specialized tools from the buyer, which makes it possible to independently carry out their installation.

PVC pipes are suitable for gravity and pressure networks. Pressure types withstand high pressure well without the formation of deformations and cracking. They do not require grounding, as the manufacturer performs their dielectric material.

Sewer pipes, like any equipment, eventually need to be replaced. Now old cast iron pipes are increasingly being replaced by modern PVC products(polyvinyl chloride), which has many advantages over metal.

Polyvinyl chloride is modern material, which has proven itself in the market of pipe and fitting products.

Typically, PVC pipes are used when laying sewers (both internal and external), in pressure systems and wells, drainage structures and gravity discharge.

PVC products are different:

• anti-corrosion properties;
• immunity to damage by microorganisms;
• smoothness of the inner surface, which prevents settling and buildup of sediment;
• dielectric properties (polyvinyl chloride does not conduct electricity);
• environmental safety, no harmful emissions;
• inertness (PVC pipes do not come into chemical contact with the transported medium);
• resistance to temperature extremes;
• resistance to barometric loads;
• long service life;
• ease of installation;
• light weight products;
• a large assortment of pipes for various purposes and fittings;
• attractive cost, which is much lower than the price of metal ones.

Passing inside PVC premises pipes in most cases do not need insulation. If such a need arises (for example, when installing underground utilities or installation under open sky), it is rational to additionally insulate and insulate the pipeline.

Types of sewer PVC pipes and adapters

Depending on on which section of the highway the product will be used, they distinguish:

1. Lightweight pipes SN-2 are used in areas with the lowest loads: when laying domestic sewage indoors, as well as in residential areas where there is no traffic load.
2. The denser SN-4 pipes are used for laying sewers under highways with moderate traffic.
3. Industrial pipes SN-8 are designed for use in district and city sewer lines, in production, as well as in areas with heavy traffic.
