I plan on running PE plastic gas pipe underground from LP tank to house. I was suprised to learn there is a specialized fitting just to make the turn from ground to surface. It seems to be some kind of metal jacketed plastic, which is exactly backwards from the plastic coated steel that must be used for underground steel.
What is this 'anodeless riser' all about?
Why is PE only allowed outside underground?
Why must the PE transition to metal before surfacing? I think heat-fused PE rules over threads. Is it an electrical grounding thing?
Is there a different procedure besides anodeless riser when using PE for LP? For instance just a heat fused transition-to-thread fitting, then threaded onto a steel elbow, the on to the usual? Thanks!
Peace,
Sanaka
