Weld Spacing; ASME Pressure Vessel
Weld Spacing; ASME Pressure Vessel
(OP)
My colleague and I are questioning the distance of a nozzel weld from a circumferential weld on a pressure vessel that meets ASME Section VIII requirements. I am sure that the welds cannot be too close together. We do not have a copy of Section VIII to check this vessel against. Can anyone give us the quick and dirty guidelines to help in our evaluation of the construction of this vessel?

would it?
As mentioned in that thread, it is perfectly legal to have a nozzle cross over longitudinal and circumferential seams. A few extra requirements, and client spec's may limit, and a design practice to be avoided, but ok with VIII-1.
