Flanged HDPE to Stainless Pipe
Flanged HDPE to Stainless Pipe
(OP)
I have a low pressure/slight vacuum gas application in Australia where I require 750 mm sch 40 stainless pipe with am ID of 743 mm. A portion of the piping will be buried, so for the buried portion, I plan to transition to PE100/PN10 DR17 HDPE. Because I need to maintain an ID of at least the same as the SS ID, I have selected 900 mm HDPE with an ID of ~790 mm. So, to connect the two together, I will need to use a 900 x 750 SS reducer to bring the SS up to the approx. OD of the HDPE. On the HDPE, I will need a stub end and backing flange, but can someone tell me what to use for the mating flanges? I can't seem to find the proper flange for each that would properly mate to each other. Thanks

I had to transition to PVC in the past with a threaded flange (steel) and used a male npt x female socket coupling (pvc). Not sure if that would work with HDPE…

See this lot. Look under accessories for the backing rings. And pupped fittings for the stub flanges.

I have accounted for this, but my question was only pertaining to connecting SS to HDPE.
