Minimum allowable distance between a pipe weld and geometry change (transition piece) in ASME IIII
Minimum allowable distance between a pipe weld and geometry change (transition piece) in ASME IIII
(OP)
Hi,
I have a two pipes that are joined by dissimilar welding and one of the pipes has a bore size change to allow the homogenous ened of the two metals to be joined (different pipe schedules). Can anyone tell me if there is a rule in ASME III that gives minimum allowable distance from a weld to a geometry change, i.e. bore change?
Thanks in advance of any responses.

You're thinking of using a transition part (reducer or adapter? ) instead of a pipe stub, but the principle is similar.

I do not think the original post was about the distance two welds.
I think it was about a possible distance requirement between the end of a taper bore bevel(on a thicker wall pipe) and a single weld joining that modified pipe to a thinner wall pipe.
Mellco, would you please clarify this for us?
