Derating factor-Y
Derating factor-Y
(OP)
Hello all!
Per 31.3/31.1, there is a relation between Temperature and De-rating factor (value of coefficient) in the Table provided.
Is there any relation with Pipe thickness and practical aspect in piping.
Thanks for your valuable comments....

What practical aspect are you thinking of - this is a vague question....
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

For lower temperatures, the result is a smaller required thickness as for larger temperatures, the Y-value increases.
Be aware of the limitations of the Y-factor for thicker components ( T>=D/6)
