Due to its link with the Water Industry WRC has been involved with uPVC pipes for many years. Rased on information gathered from several WRC exercises involving detailed evaluation of operational data, research into pipe failures and information from other suitable sources this paper discusses various aspects found by experience to have affected the installation and performance of uPVC pressure pipelines. Failure rate comparisons are made with cast iron pipelines. Laboratory investigation techniques are discussed. Pipe users have expressed general satisifaction with uPVC pipes and failure rates have fallen but a need for extra care in installation and manufacture is apparent.

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,...

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...
