@ Ed stainless, Code allowable at 649°C is 8.2MPa.
@ GD2, The working temperature is 560 to 580°, design 649°C.
Thanks for the idea, in API 530 usable tables are given.
I think I can work this out further.
Thanks for all your idea's.
Hello MJCronin, I’m indeed in search of information. Sorry English is not my native language.
This has to do with a fitness for service assessment.
We have in a running plant a special problem with P11 that’s is under corrosion attack.
This only happened after the previous P11 part was renewed...
Hello,
I'm in surge for Yield strength of A335 P11 materials at temperatures above 525°C.
Allowable stresses go upon 650°C in ASME II. Yield stops in ASME II at 525°C.
I found tables in PV Elite but to me they are not really trustworthy at these temperatures.
Those somebody know an solution or...
Hello,
We are facing a problem with a thicker component in a ASME VIII div 1 pressure vessel with a minimal design temperature of -46°C.
The vessels required thickness is determined by its external pressure giving it a min required thickness tr of 43mm. The internal pressure gives a tr of...
