Temperature Derating Factor
Temperature Derating Factor
(OP)
Good evening,
For thickness calculation
What does this factor accounts for? and why is it only used in ASME B31.8 but not ASME B31.3 & B31.4 ?
Your accurate response is highly appreciated.

31.3 has defined values (table A1) for S to be used as allowable stress for many different materials versus temperatures.

Thank you.

I have no issues with you asking questions, that's why I respond. However for this and for the future, it is much better for you and your superiors / forum members if you have a look at the relevant codes etc first and then either say "I've looked at XYZ" and I'm not clear / can you confirm", is much better than "please tell me".
Ok, I knew where to look to give you the answer, but it wasn't hard and you could have found this out by a small amount of looking at the codes in question.
