Pipe Design - Length between Buttwelds
Pipe Design - Length between Buttwelds
(OP)
Does anyone know of a Code reference or limit that specifies a minimum distance between pipe buttwelds such as 1.5D for example. I looked but can't find any such limit in B31.1 or ASME III. Maybe I missed it or it is covered in another piping code. Thanks and Merry Christmas/Happy Holidays to all.

What I have seen only seems to think it's a problem with high spec steels and carbon steel is not a problem. Pisses me off when inspectors do not allow close welds but can not back up why.
