Service Failure Experience of uPVC Pressure Pipes in the Water Industry


Water and Building Industry

Plastic Pipes Conference Association # 1982 York

Stephens, Gill

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.
