Rerounding HDPE Pipe
Rerounding HDPE Pipe
(OP)
Has anyone ever rerounded HDPE pipe after a vacuum collapse? I have a 4"/8" dual-contained HDPE force main. The 4" pipe collapsed, apparently after a vacuum release valve failure. I am exploring options to complete replacement of the pipe.

Are you sure interior pipe is not e.g. instead "necked-down" as with pulling load, or alternatively has leaked and leakage is exerting/has exerted excessive external pressure in the interstice between the casing and carrier, and thus against the outside of the 4" pipe?
