TEPPFA position 100 years lifetime of Polyethylene pressure pipe systems buried in the ground for water and natural gas supply

Joint position paper of TEPPFA and PE100+ Association explains the difference between the design point at 20 degree/50 years and the expected life-time of PE80 and PE100 pressure pipe systems.

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