Creep Temperature for API X52 PSL2 Material

Creep Temperature for API X52 PSL2 Material

Creep Temperature for API X52 PSL2 Material

(OP)
Does anyone know at what temperature creep becomes a factor for API X52 PSL2 Material?

RE: Creep Temperature for API X52 PSL2 Material

Use 700 deg F or higher for time dependent properties.

RE: Creep Temperature for API X52 PSL2 Material

(OP)
Do you have a source for that information? This for a piping system operating at 10,000 PSI and 250°F.

RE: Creep Temperature for API X52 PSL2 Material

My source would be use of equivalent materials as found in ASME B&PV Code, Section II, Part D. At 250 deg F you are well below the threshold for time dependent properties. The UTS or YS will govern piping design at this service temeprature.

Thank you very much!

This is he same approach we have been using but have had trouble getting the authority to accept our design.
