First of all, thank you for all your comments.
I will try to simplify the problem.
Suposing that due to design considerations that cannot be modified, the support lugs of a vessel are exposed to 1200 ºF.
The materials that we want to use are SA387Gr91Cl2 and Sa387Gr22Cl2 due to supply.
The...
What I meant is that we want to use ASME materials, but the room temperature is above 1000 ºF, and for that temperatures the only data available in ASME Section IID is the maximum allowable stress, and it is rather confusing, because some materiales are said to be suitable for higher...
First of all, Happy New Year!!!
We are making an special and odd design where some support of the vessel are exposed to high temperature, far above the 1000 ºF specified in the tables of ASME Section IID for the majority of the characteristics of the materials, apart for maximum allowable...
