Reliability of polyethylene pipes

摘要：

Polyethylene pipes have been used for many years for the supply of drinking water and gas. In Europe,high density polyethylene (HDPE) was already being used at the beginning of the 1960s. Since then, thematerials have undergone continual improvements. The so-called second generation HDPE materials were produced in 1980.They were characterized by the integration of comonomers to satisfy the demands for greater resistance against environmental stress crack (ESCR) and a bettercompromise between flexibility and long term strength. Requirements and demands on pipes and raw materials have increased. Damage found in the soil has made itnecessary to define the requirements for slow crack growth and rapid crack propagation of the fracture.Second generation PE materials have finally reached their limits.
