Gas pipes ― qualification of plastic pipes for 10 bar

摘要

PE 100 pipes were introduced as a possibility for use for natural gas in Sweden and Norway. The authorities had no doubts that the pipes were suitable for what they were designed. The main issue was whether the pipes were suitable for the same proximity distances or if they had to be altered. This paper explains the philosophy behind the Swedish ― Norwegian distance requirements and why the authorities accept that the PE 100 pipes may have the proximity distances already used for steel pipes.
