Dimensions of plastic pipes for sewage. Plastic pipes for sewerage: standards

Sewer plastic pipes, types, the sizes of which are presented below, have recently become the most popular. They are made of polypropylene, polyvinylchloride, polybutylene, and polyethylene. Such products are in demand in the arrangement of sewage systems, which are characterized by resistance to the influence of corrosive substances. You can lay pipes in household or industrial soils. Quality products have an ideal smoothness, which eliminates the possibility of clogging. At installation it is necessary to apply a traditional hacksaw, intended for metal, whose teeth will not form burrs.

Description of plastic sewer pipes

Plastic pipes for sewerage, the dimensions, the standards of which will be described below, are made of polymer compounds. The technology guarantees durability, reliability and durability of the sewage system. You can use the material both inside and outside the house. The throughput remains unsurpassed, even if the pipe bends at the required angle. By equipping the sewage system, you can count on reasonable cost, durability, and also the lack of the need for cathodic protection. Thus, after carrying out the work there is no need for constant maintenance. Pipes are characterized by low thermal conductivity, which prevents freezing of waste water. The weight of the products allows them to be mounted without the use of special equipment, and reliable protection eliminates the spread of viruses and bacteria.

Dimensions

Plastic sewer pipes, the advantages of which are described above, can have different sizes, each of which is provided for a different degree of load. If there is a need for a sanitation system for an apartment building or a social object, then a more impressive diameter should be used. Thus, the above figure of 200 millimeters is suitable for hospitals, hotels or saunas. An impressive diameter, equivalent to 300 millimeters, is used in the operation of industrial facilities. The types and dimensions of plastic pipes for sewerage must be selected before the time of commencement of work. In individual construction pipes of very insignificant diameter are used. Thus, if you use 150 millimeters when installing a riser, it will not be fully used, which is true for a house with a maximum number of bathrooms limited to four.

Standards of sewer plastic pipes

In accordance with the nomenclature, sewer pipes made of plastic are made, the diameter of which can be 50-110 millimeters. The thickness varies from 3 to 3, 2 millimeters. For the arrangement of external sewage , a second variety should be used, which is capable of providing the required mechanical strength. If you need plumbing plastic pipes, how to choose the dimensions is important to know even before purchasing. However, it is important to decide what kind of products will be needed. For example, external joints, including industrial joints, require the use of corrugated pipes made of double-layer polyethylene. Among the main advantages in this case can be distinguished chemical resistance, excellent ring stiffness, which allows to lay at a depth of 20 meters. For the arrangement of pressure systems, sewer polyethylene pipes are used, which have the appropriate properties. The diameter can vary from 10 to 1200 millimeters.

Use of HDPE

Dimensions of plastic pipes for sewerage have been mentioned above, but it is important to determine also the variety of the product. Among others, it should be noted low-density polyethylene, which is characterized by high strength. It excellently resists the influence of an aggressive environment.

GOST 22689.2-89

It is important to properly choose the dimensions of plastic pipes for sewerage, as well as determine the variety. The above-described corrugated products are not regulated by state standards and can be manufactured under conditions that are preliminary agreed with the customer. As for polyethylene pipes for arranging internal communications, the GOST, mentioned above, is used for manufacturing. It states that the pipe can have a size between 2 and 8 meters. The following parameters are the intermediate values: 3; 5.5; 6. For internal work, the diameter of such a pipe can be from 40 to 110 millimeters. The intermediate values are 50 and 90 millimeters.

Restriction in use

It is important to correctly choose the dimensions of plastic pipes for sewage, but you must also take into account some limitations of use. The standard assumes the use of pipes for settling gravity in the sewage system. With regard to pressure systems, they comply with other regulatory documents. Despite the standard, a polyethylene pipe, which is equipped with a rubber seal, can become part of the system using drainage pumps. If the pressure is negligible, this connection will be abundant enough. The types and sizes of plastic pipes for sewerage will allow you to equip the system correctly, but it is important to take into account some points that must be observed during operation. Thus, the products are designed for a temperature that does not exceed 45 degrees. However, short-term increases are permissible, which can reach 60 degrees.

This requirement is recommended to be taken with particular severity, excluding the use of a system for the discharge of water, which has a high temperature.

Recommendations

Plastic pipes for sewerage, the sizes of which can be very different, are used for laying systems both in the city and in the countryside. Such pipes are used increasingly often because they are completely immune to soil movements and are characterized by ductility and flexibility. Plastic pipes for sewerage, the size of which you must pick up even before the start of work, are not electrically conductive, have good corrosion resistance and are not afraid of exposure to corrosive media. You can not be afraid of the fact that moisture and dampness will be able to affect the performance characteristics of the material. Among other things, the surface is not a favorable environment for the emergence and reproduction of bacteria.

additional characteristics

Using the products described, you can count on a long service life of the material, which is guaranteed for 50 years. If the installation was carried out correctly, and the operation was carried out in accordance with the rules, then this period may be increased. Customers choose the product data also for the reason that they are able to absorb noise, which is an advantage over other plastic pipes.

Conclusion

If during the work you use corrugated pipes, then for their joining we use sliding couplings. They are chosen when laying the system in the soil outside the premises. In the arrangement of internal networks, where it is customary to use trumpet pipes, manipulations should be carried out using the same technology used for any other plastic pipe equipped with sealing rubber rings. When performing work as one of the most important conditions, it is necessary to use high-quality components.
