Plastics Pipes Underground # 1970 Southampton
The pricipal plastics materials used for the distribution of potable water supplies in this comtry are uPVC and polythene. uPVC is now available in pipe sizes up to 24 in. and its use in the UK has increased rapidly since the first pipe of this material was laid in 1958. Polythene pipes have been used for rather longer but their application to water supply is mainly restricted to service pipes of small diameter.
This paper will refer to experiences with upvc. The advantages of these materials for water supply pipes are well known and have been fully discussed elsewhere.

The objectives of this research are to better understand the degradation of cross-linked polyethylene (PEX) tubing subjected to pressurized, hot chlorinated water in flow-through systems (like home plumbing) and to estimate its service lifetime. PEX tubing was subjected to pressure testing with flowing hot,...

The introduction of a new grade of polyethylene for pressure pipes has presented a challenge to the UK Water Industry. Some aspects of the performance of the pipe itself are claimed to be significantly better than those of existing MDPE grades which would offer significant economic and operational benefits. However,...
