Natural Gasline material
Natural Gasline material
(OP)
We want to lay an underground pipeline from a nat. gas metering station to a turbine on site.
What material and possible coating should be applied?
Location Western Europe.
Des.press. 35 Barg
Des.temp. -20/+60 deg.C
Pipedia DN150
Pipeline length 120 mtr.
Please don’t reply when you think the question is not improper.
Thanks in advance.

According to ASME B31.3, the minimum temperature without impact testing is as per curve B of Fig.323.2.2A in ASME B31.3.Therfore impact testing is not needed until -30 deg.C if the wall thickness is below 10 mm.
I think that Sch.40 is sufficient for the wall thickness of that pipe even though corrosion allowance 3mm is considered.
