HDPE pipeline

[Patinina]

Hi
I will use HDPE material for a pipeline of 6"@250 psi/ 20C.

Everyone have this experience?

Maybe someone will hve some ideas?

How do you guarantee that a pipeline stays at 20C?

Hi guys, thank you for replay.
This is a colector pipeline from other steams.
Working temp is 20C, is U/G pipeline.
From all clculations I need it for 300 psi, but max goes for SDR=5 / 6" results for 250psi.
This is my problem, I need it for 300 psi.
Solutions?

Pick a material with the correct HDB (or MSR) that is listed in TR-4 at this site:

Thank you S Jones,

I picked up
HDPE PE 4710/ 250 psi@ 20C
with B31.3 fittings andsome plastic fittings.
I need sleeve on for corrosion protection/ fabricated fittings/ O-rings etc.

Global Polly Systems
Fittings from

However I had to go for 8 -1 0" pipeline.

Mike:
The material is designed to work at this temperature nd it goes max 60C( I never like to pick the mx temp).
The working conditions/ flow raate etc re exactly like for steel pipe.
The difference is in corrosion- much less, but again some points are subject to leak.
