Rogers Karr,
Thank you very much for the reply, I think i see it a little better now after your reply. After reading UW-11(a) i understand what you are saying, what was throwing me of is that the engineer refered to UW-11(c) and category A joint, Rogers, this is what was sent back to me for the Ellipsoidal Head (8" Pipe Cap)
Radiography: Category A joints- Seamless No RT
Head to shell seam- None UW-11(c) Type 2
I tried for a week to get in touch with the engineer to ask these questions with no replys,
I think i have missed up for the moch up vessel is built with the heads welded with full-pen without backing, I told the guys to go ahead and weld them full-pen for i didnt know at the time, as i said this is just a moch vessel for a trial run, the AI Supervisor will be here in the morning. I remember going through this when i was at Alstom Powers and there were no backing on the joints, just full-pen on the shell when welded, I was the one welding, not the one checking calcs and so forth, plus we were building HRSG's which would not fall under section VIII.
Again Thanks,
Strat
