TEPPFA Position on 100 Years Lifetime of PVC-U and PVC-Hi Pressure Pipe Buried Systems for Water and Natural Gas Supply

Joint position paper of TEPPFA and PVC4Pipes explains the difference between the design point at 20 degree/50 years and the expected life time of PVC-U and PVC-Hi pressure pipe systems.

Research, extrapolation studies and studies of dug-up pipes in service for years, show minimal degradation and extrapolative tests performed on these test samples confirm an expected service life in excess of 100 years.
