Features sewer polyethylene pipes

Technical indicators polyethylene pipes

GOST 18599 - 2001 for the production and use of plastic articles regulate the following characteristics:

• obligatory control the appearance of the pipe, there are no visible defects;
• at rupture of the pipe, it must extend to the destruction of the site by 250%;
• strength of the product during heating;

• polyethylene pipes must withstand the internal pressure drops.

Polyethylene pipes are used for the construction of internal and external sewage with a range of operating temperature 40º - 55 ° C.Guaranteed service life - 50 years.

advantages of polyethylene pipe sewage

1. Resistance to corrosion and action of chemically aggressive environments;
2. long service life (up to 400 years);
3. High reliability and durability of plastic construction;
4. Low cost, compared with the same steel and cast iron;
5. Simple installation of sewer polyethylene pipes without the use of expensive equipment;
6. Low weight of the whole structure.

main disadvantage of plastic pipes is their exposure to sunlight and high temperature, so these factors should be considered when planning the replacement of sewer.

technological process of production of polyethylene pipes

technological process of production of sewer pipes made of polyethylene comprising the steps of:

• tube made of polymer mass by extrusion;
• tubes Calibration using a special nozzle;
• Application templates to generate the appearance of the pipe;
• Normalization products;
• marking and storage of the finished product.

for sewer purposes use polyethylene pipes of two kinds:

1. HDPE pipe (made of low pressure method);
2. Pipes LDPE (high pressure material).

characteristics pipes made from these types of materials differ in density and are used for arranging sewers with different operating conditions.

Installation of sewer polyethylene pipes

to hold the installation of the sewer system of PE pipes spent a bit of time, and this installation does not require the use of special tools and devices.Enough to have a simple set of metalwork, which includes a hacksaw, measuring tape and a screwdriver set.A compound of structural elements takes place by means of special fittings.This adjustment can be performed in any temperature range that makes it attractive mounting robots of this material most repair organizations.

should also be noted that the laying of sewage pipes from PE occurs by connection of its parts without the use of welding equipment, which is required for installation of steel structures.For more information about the methods and techniques of polyethylene sewer installation, see the article "Installation of plastic pipe."

Another positive characteristic of laying sewer polyethylene pipes is their low weight.This quality excludes the use of lifting devices and mechanisms for mounting the sewage system, both on the ground surface and in the middle of the old cast iron pipe.
