Question: when rating equipment to temperature class x or y - I have the following questions.
If one doesn't wish to qualify the material at the high temperature mechanicals.
Can you use the derating the factors in Table G3?
If you use these factors - are you calculating to the working pressure since the hydrostatic conditions are tested at room temperature?
I typically use the Distortion Energy Theory (4.3.3.2) but App. G appears to discuss only the ASME method and doesn't mention the distortion energy theory.
Can anyone shed some light on this?
