Nasir,
I respectfully disagree:

Quote:

Interpretation: VIII-1-83-217

Subject: Section VIII-1, UG-11 and UG-45
Date Issued: February 22, 1984

Question: Are threaded couplings welded directly to a pressure vessel to be designed per ANSI B16.11 as stated in UG-11, footnote 5, Section VIII, Division 1, thus disregarding the requirements of UG-45 for nozzle neck thicknesses, since no neck exists?

Reply: Yes.
