Fit up and Gap Spacing
Fit up and Gap Spacing
(OP)
Is there any where in any Procedure that states you have to use a certain gap spacing/ root spacing per pipe schedule. Ex if I have a 3'' s40 pipe what tells me that I should gap space it at 1\16'' or can I just space it at what I fell confrontable in doing.

Standard WPS use a 1/8 root gap for open root butt welds; you'll have to work real hard to justify a different gap.
