Echo11,

I’m agreeing with you. In my earlier post, I reached conclusions identical to yours. Designers do not have to add anything to the reference dimensions shown on butt weld fitting charts.

When I brought up the 1/8″ gap I was responding only to the idea that you don’t have to worry about weld gaps because its ONLY 1/8″. My point was that if 1/8″ WERE added to each weld, it could be a problem in some situations. In fact, 1/8″ is NOT added to each weld.
