TEPPFA PE100 Position on 100 years lifetime expectancy of PE Pipes

TEPPFA and PE100+ Association have identified the need for explaining the difference between the design point at 20 degree/50 years and the expected lifetime 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.
