Proof Test - UG-101

[BPVN]

Hi All,
Can i use UG-101(M) to calculate MAWP of modified "T" (Fitting) ID, which i want to use in pressure vessel?
If yes, code reference and what dimensions, NDE, report require.
Can my sister company use the same proof tested report to use modified fittings to their vessel?
Your promot reply will be highly appreciated.
Thanks in advance

You can use UG-101(M) to establish the MAWP for anything that would be under the purview of Section VIII Div1 providing that there are no rules for that construction. You mentioned that it is a T fitting - that sounds like it may fall under piping and not under Section VIII. I would discuss the documentation requirements with your AI.
