VESSEL MAWP VS TEMP
VESSEL MAWP VS TEMP
(OP)
Hi I'm wondering if there is a Vessel MAWP vs. Temperature rating, much like the ASME B16.5 flange pressure vs temperature (attached). We are installing a separator on a line which is expected to be running at 80 DegC so I'm wondering if I should have the PSV set point lowered.

Your post implies that you are operating either at a high pressure, but lower temperature or you're planning on increasing the operating temperature above the design temperature?
Either one really needs a re-certification not a simple chart of pressure vs temperature.
All flanges to a certain spec and rating and material are the same, but every vessel is different.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
