B31.3 Radiography requirements
B31.3 Radiography requirements
(OP)
Article 344.5.2 specifies 100% radiography for girth and miter groove welds in paragraph (a) and random radiography for the same welds in paragraph (b). How do I discriminate between the two rules?
We have a pipe to pipe butt weld 55mm thick.
(We do not have a fabricated branch connection)

The rules in 344.5.2(b) apply to those miter and girth welds in pipe systems subject to random examination under 341.4.1(b) and M341.4(b).
