ASME Appendix 2 Fabricated Flanges
ASME Appendix 2 Fabricated Flanges
(OP)
A flange is designed to ASME Code Sect. VIII Div. I, Appendix 2 and manufactured in 3 x 120° segments welded together.
Do these butt welds require any NDT? Any references for this construction?
Thank you

Ring flanges are often made as you propose.

RE: ASME Appendix 2 Fabricated Flanges
In this case we have a 2 1/2" thick 304 SS flange and we would like to make it from 3 plate segments, no hub. The only issue, I believe, is radiography, and I just can't see this type of construction addressed anywhere. Do we need radiography of the three 2 1/2" thick welds?
RE: ASME Appendix 2 Fabricated Flanges
While it may not be explicitly called out I would consider this a catergory A joint, and would full RT.
In any case, I would full RT these welds regardless of specific requirements for my own piece of mind.
