The fact that the polyethylene does not suffer from corrosion it is not affected by chemicals, the high resistance to abrasion brings the advantage of life over alternative products. It has a service life of at least 50 years. The networks can be out of use due to earthquakes. Experiencing earthquakes have shown that POLYETHYLENE PIPES are available from earthquake rigid pipes are completely disabled and new lines are laid. In locations where erosion is experienced, the Pe 100's absorption is prolonged due to its 600% elongation capability. Landslide solves the problem on the lines that have to be changed frequently in the regions. The fact that it can be produced at different pressures in accordance with the project saves raw materials and has been effective in the feasibility of the projects. POLYETHYLENE PIPES (Pe100 and HDPE) are most commonly used in Scandinavian countries
