Pipe Performance Lessons From UKWIR and Severn Trent PE Project
Pipe Performance Lessons From UKWIR and Severn Trent PE Project
UKWIR and Severn Trent recently exhumed test PE pipes from special testbeds
UKWIR and Severn Trent funded a project to examine the recently exhumed plastic HDPE pipes from special testbeds at two Midlands’ pumping stations. The pipes in the testbeds were originally installed in the early 1980s and 1990s and were kept “in-service” while also being subjected to specific chemical and mechanical testing to determine any changes in performance, such as leaks or bursts.
Results of the project show that PE pipes with characteristics similar to those of the exhumed pipes will last much longer than the expected 50 years. In addition, high-pressure pipes, such as PE100, could last as long as 160 years. The project also found that most joint failures are caused by installation issues, signifying that monitoring and improving workmanship are critical. The data gathered will also allow utilities to better assess new pipe materials, plan for future system investments, and more accurately predict the durability of plastic pipes.
