Dear experts;
We have a skid of piping 10 " and 2 " API 5L welded and inspected according B 31.3.
we made already the internal hydro test ( two houres at 375 bar) in workshop and the result was satisfactory , we repeat the same hydrotest in the client workshop and we found a leak in one 2 " joints.
the RT report for this weld mention only undercut ( acceptable).
how we can explain this ?
regards
