jacket closure & general primary membrain stress
jacket closure & general primary membrain stress
(OP)
i want to know whether jacket closure has general primary membrain tensile stress?
If not, i want to know where it is marked as criterion on the Asme code section VIII Division I.
please advice about that.

RE: jacket closure & general primary membrain stress
However Div.1 does not classify stresses as membrane, bending and the like, they do not tell you whether there is a general primary stress in the closure, just by what formula you calculate the thickness.
Anyway a jacket closure is just like other vessel parts: if it's flat, it has only primary bending like a flat head, if it's conical or formed, it has also general primary membrane stresses like a conical or formed head.
