Branch on B16.9 Fitting?
Branch on B16.9 Fitting?
(OP)
ASME B31.3 basically considers a branch as it welded on a run-PIPE.
ASME B31.3 and ASME B16.9 consider a fitting as a seamless pipe.
My question is: when a branch is welded on a B16.9 Fitting (elbow / reducer / tee / cap) – has this fitting been considered as "Unlisted component" acc. to 304.7.2 ?
Does size of branch makes any different? When branch is made of a #2000 (or heavier) coupling acc. to 304.3.2 (b)?
Thank you very much in advance!
