How to solve this issue in accordance with the ASME B31.3 standard - Pipe seams continuously weld

[rufi4212]

Issue - During the pre-commissioning phase, the commissioning team discovered an issue with a 12-inch two-pipe weld, specifically that both pipe seams were continuously welded and the line has successfully hydrostatic testing has passed, and non-destructive testing (NDT) has successfully done.

So what is the issue if its passed hydro and NDT??

IMO, for the piping construction, any pipe weld needs to be repaired prior to hydrotest if there is a NDT issue of the weld.

Does this 12" diameter pipe have 2 weld seams? If so how can it be continuous welded?

I wonder if the issue is the two x longitudinal seams are aligned and not off-set ?

DekDee, I suspect that is the issue.

AFAIK, this isn't a requirement in B31.3 just usually in a construction spec.

You mean welds are not offset on ow different joints? There is still a girth weld in between them, they are not continuous... Not a big issue.
