High pressure poly
High pressure poly
(OP)
Hi,
Is anyone aware of a poly pipe product that is suitable for approx. 26 barg design pressure in 24" (natural gas service)? It's off the charts for the usual products, but perhaps there is a more advanced product that I'm not aware of.
Thanks

RE: High pressure poly
A lot of the fibre reinforced stuff goes up to 26 and beyond, but PE will just end up too thick.

RE: High pressure poly
The 20 barg product that LittleInch mentioned has that rating at 23 C in clean water. Any other product or higher temperatures drops that number quickly.
If you have a legitimate need for poly and for your pressure rating and for the pipe size, don't screw around with half solutions. Using SDR-7, you would need to go to a 36 inch nominal product in HDPE to get 24 inch ID.
