How do you perform the verifying these points? Our procedure states that we verify it at the level of design (using centering pins) and incoming control via a 3D arm but for an inspector it was not sufficient as he asked for verification on the valves even after assembly and hydraulic test...
Hi all,
I would like to ask you the following question. According to API 6FA, API 607, ISO 10497, could a welded closure valve be qualifed (as extension criteria) from a fire-safe certified bolted closure valve, assuming that internals are the same?
