Welding of Large Diameter Heavy Wall Polyolefine Pipes and Long Term Performance [PE]

# 2004 Milan

Case histories of large diameter heavy wall polyolefine pipe installations for water supply in Japan are presented. The different methods for heated butt welding procedures for polyethylene are compared. The test methods to assess the performance of the welds are described and the failure mechanisms are discussed. Basing on experimental results the long term performance of a butt welded polyethylene pipe is predicted for a service life of more than 100 years.
