Joe, Great example of this point. There's a schedule 40 riser with cut grooves in one of the Pike Place Market Buildings. This is riser is a twisty thing made of several small sections of 6" pipe. Several of these sections developed leaks at the cut-grooves (this time definitely at the seam weld). After the second time we figured all these short sections were probably fabbed from the same joint and so replaced everything. I don't know if the cuts were within spec or not and because the work always had to be done between 2 AM & 6AM I really didn't care. So, what is the equivalent schedule of the pipe in a properly done cut groove?
