I have another doubt on radiography. As per ASME Section VIII Div-I UW-11 (a)(4), category B and C welds in nozzles that neither exceed NPS 10 nor 29mm wall thickness do not require any radiographic examination. Recently i reviewed one mechanical GA drawing for surge vessel. In which, 16inch nozzle connected with main shell. But fabricator state that full radiography should be given on category C welds in nozzle and if radiography is not accessible 100% UT should be given. Please clarify which statement is correct?

My understanding is correct or not. Please clarify me.

NPS 16 exceeds (is larger than) NPS 10.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
