Pressure pipes made of polyethylene HDPE (GOST 18599-2001).
Pressure pipes made of low-pressure polyethylene are intended for pipelines transporting water (including for household and drinking water supply) and other liquid and gaseous substances to which polyethylene is chemically resistant.
Pipes are made of low-pressure polyethylene by continuous screw extrusion.
Polyethylene pressure pipes take precedence over metal pipes:
- water frozen inside a plastic pipe will not damage it;
- subsidence of the house to which the pipeline is connected will cause the destruction of the metal pipe, while the polyethylene pipe can stretch without losing its qualities to 7%;
- polyethylene pressure pipes are toxicologically and bacteriologically safe;
- easy to maintain (polyethylene pipes are easily replaced);
- polyethylene pressure pipes are not classified as dangerous goods.
- tightness-pipeline systems are uniform and monolithic due to connections made by thermal welding;
- resistance to aggressive soils;
- high strain tolerances virtually eliminate the breakage of the pipes at low temperatures;
- strong and light HDPE pipes for transportation and installation do not require heavy equipment;
- operating temperature of HDPE pipes (+60° C) (-50 °C);
The color of the pipes is black, uniform.
The outer diameter of the produced pipes is from 10 to 1000 mm. Pipes produced in straight portions (from 6 to 12 m by agreement with the consumer) are bundled in packages.
Pipes with a diameter of max 110 mm are manufactured in bundles from 100 to 2000 m.
