Thank you all. I think I will stick to what ASME VIII par. UW-14 b) says that provided the weld meets the radiographic requirements in Par, UW-51(m) you can make an openning in or adjacent to welds.
May be also testing the hardness of the welds, could give another assurance. A fitting...

Thank you all.
I see that there is no clear definition on this subject.
I have been looking at ANSI B31.3 and there is no reference about this.
Someone mentioned that in ASME SEC VIII DIV 1, UW-14 you were allowed weld-on-weld connections. Can anyone check this for me as I don't have the code?
Thank you all.

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?
Thank you for your replies.
Really I am concerned with the allowable spacing between adjacent welds, because the spools have to be a given length, the flanges have to be WN and the welds of the flanges are resulting 78 mm apart.
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.
