Where can I find the minimum allowable spacing between adjacent welds for an 8" Sch 40 A-106 GR.B pipe? I need to make a small spool with WN flanges on each end and the flanges are resulting in 78 mm apart. Is this spacing OK for the welding?
I need to make a pipe spool with an 8" Sch 40 A-106 GR. B and two welding neck flanges A-105 Class 300 and I need to know the minimum spacing for the welds of the flanges, so as to make the spool as small as possible.
