Hi,

I'm a stress engineer for 5 years now and work in Belgium.

I have some trouble finding the correct materials for fittings and flanges.
I'm not yet an expert in gas transport.

The pipe material is API-5Lgr.X52.
Service: gas transport, 1500#, 10".

I suppose
the fitting material is A860gr.WPHY52
and the flange material is A694gr.F52.

Can somebody confirm this?

I'm also looking for the p/T-rating for this flange material.
This material is not mentioned in ASME B16.5
MSS-SP44 begins at 12" and does not mention 1500# flanges.

Can somebody help me with this problem?

Kind regards,

Yke
