Badpip Posted March 12, 2020 Share Posted March 12, 2020 It's because you try to pump a gas who liquefy inside "cold" gaz conduit Link to comment Share on other sites More sharing options...
beowulf2010 Posted March 12, 2020 Share Posted March 12, 2020 Or more specifically, the water vapor is condensing into water in the gas pipes which cause "cold damage". Any time a gas or liquid changes into something else (water<=>vapor, oil=>petroleum, oxygen=>liquid oxygen, etc) and the mass is more than 10% of the maximum volume allowed for the piping, it will cause damage based on which way the phase transition happened.

Badpip Posted March 12, 2020 Share Posted March 12, 2020 If you want a simple way to avoid this is to remplace your gaz pump with a mini gaz pump Edit : yeah mini gaz pump overheat at 75°c and can't be build with gold for extra °c sorry for that false information.

That would depend on the metal used to construct it, would it not? Link to comment Share on other sites More sharing options...

The pipe before the valve will keep breaking though. You need at least 2 segments before you put the valve. If it`s insulated it might help a bit but it needs to be at least ceramic.
