The Long Term Behaviour of Buried uPVC Sewer Pipe

 

PVC - Pipes and Pipe Systems # 1988 Bath

One of the main reasons that plastics have not found more extensive use in non pressure sewer schemes has been concern about the long term deformation characteristics of the pipeline. In order to investigate this phenomenon the flexural behaviour of u W C sewer pipes installed in Western European countries, including the U.K., have been monitored by Wavin over the past 23 years. The results of this programme of work is presented in the paper and illustrated by a number of specific case histories.
