API 650 - Shell openings - Spacing of Welds around Connections

[Allcciinneeii]

Hello!
According to item 5.7.3.4, Nozzles and manholes should not be placed in shell weld seams and reinforcing pads for nozzles and
manholes should not overlap plate seams. But in case it is not feasible, then the welded shell joint shall be fully radiographed for
a length equal to three times the diameter of the opening, but the weld seam being removed need not be radiographed.
My question is if this is always applicable even for stainless steel tanks designed according to API 650 annex S with joint efficiency equal to 0.70.
Thanks and best regards!

I'd say that's a good one for a "request for interpretation". Table S.4 says "No radiography required" which implies it is not required. But for E=1, it's "Radiograph per 8.1.3", which implies that the radiography being omitted is only that in 8.1.3.
