How can I calculate pipe wall thickness under external pressure?
How can I calculate pipe wall thickness under external pressure?
(OP)
Hi everyone :D
I have question about pipe wall thickness under external pressure condition.
I know it can be calculated in accordance with ASME BPVC SEC VIII - UG 28.
In this code, I must determine factor "A" and "B", and it can be determined in ASME SECTION II -1.
But, sometimes I cannot determined factors because Do/t or L/Do do not exist in the table G (in the ASME SECTION II- Subpart 3)
In this situation, what is the best way to determine the factor A & B?
Plz, help me.
Best regards, Moong.

Or... You could read VIII Div. 1 UG-28, and then review charts in Section II Part D. Specifically, UG-28(c)(1)(step 2) and UG-28(c)(2)(step 1 or step 2).

There is a good paper, OMAE'99, PL-99-5033, BENDING MOMENT CAPACITY OF PIPES by Soren Hauch and Yong Bai, that outlines the calculations.
