Tube elbow standards, ASME B16.9
(OP)
Is there a comparable standard to ASME B16.9 for butt-weld tube fittings (OD x wall thickness)? We have had issues in the past with vendors supplying incorrect tube fittings e.g. long vs short radius, different tangent lengths, etc. I am trying to avoid this by calling out a dimensional standard.

Also, keep in mind B16.9 specifies, in general, main fitting dimensions for piping according B36.10/.19. ASME B16.25 specifies dimensions for welding ends based on various OD and wall thickness combinations.
