The technical pipe SDR 26 diameter is 110 mm

Pressure head pipelines of the giving, sewer systems and drains of an internal and external arrangement are manufactured of this look. As the main advantages which possess { polyethylene pipes } this type are considered: • low cost; • small weight; • simplicity of installation; • small heat conductivity; • resistance to chemical influence. A lack of a pipe polyethylene - flexibility, bad in comparison with other plasticity, is considered. Polyethylene of this type is made low and high density for pipes of a low and high pressure respectively. The main product of polyethylene of high density is the pipe water systems of cold water supply. At the expense of the high durability of material such pipe is capable to sustain freezing in its water and after thawing normally to work
