Dear Ali,
You see, without going in to much theory, I surmised from what you gave in the parenthesis as follows:
If the strength goes down with increase in temp , you will need more thickness, naturally, as compared to when you operate at low temp. I hope this clears it.
Rgds,
Shank

dear Shank Vagal can you explain more?because my point of view from writting parenthesis is the required minimum thickness (with assuming constant work presure)decreases. rjd

CAN ANY BODY EXPLAIN,WHY Y (IN B31.3 FOR CALCULATING THICKNESS) INCREASES WITH INCREASING TEMPRATURE? (ACCORDING TO ALLOWABLE STRESS DECREASES WITH INCREASING TEMP) REGARD ADVANCE
