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

Author(s) : Norbert Jansen, Albert Lueghamer

Demand for polyethylene (PE) pipe continues to grow on a global basis. The performance properties of this tough, durable piping material are widely recognized by the engineering and design community on a worldwide scale and the range of applications expands. The evolutionary trend in PE piping systems has been very...

Ultra pure water (UPW) is an important resource in several industry sectors. A project in The Netherlands is presented where a pipeline for the transportation of UPW was recently built using PP pipes with a diameter of 280 mm (SDR 17.6). The project was unique in several ways. While typically UPW piping systems are...

As part of the Polytec Systems European-funded project, electrofusion (EF) joints in polyethylene (PE) pipe, containing different flaws, have been subjected to various standard and non-standard, long-term and short-term, coupon and whole pipe tests. The results were compared to determine which tests could discriminate...

By applying the cross-linked EF to the cross-linked PE(PEX) pipe \vhicli has a composite structure, the reliability of hot water piping system under severe environment lias significantly increased. A continuous use for approsimately 30 years under severe conditions such as 80 "C. and I MPa becomes possible. In this...
