    allowable spacing between adjacent welds in 8" pipe

    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?
