structural welding directly on pipeline forbidden
structural welding directly on pipeline forbidden
(OP)
According to the ASME it is not allowed to make longitudinal welding directly on a pipeline wall.
I have seldom seen any circonferential welding directly on the external wall of a pipeline. Standard practice I have seen were to limit to butt welds only.
I could not find any standard that would forbid me to weld directly on the external side of a pipe joint (indeed I am taking about a fully qualified and ndt-ed weld).
Could someone provide me reference of a guidance, code, norm or standard that does not allow to weld structural components (such as beam, clamp, etc...) directly on pipe (ie pressure vessel)
Thanks
