I would normally expect out of parallel to be A. That is by far the most common problem.

   When preparing to bolt up a gasket between two flanges, if a    pipefitter were to say the flanges were "out of parallel", what    exactly would he mean by this?

   Would he mean:

1. Each flange face is flat, but relative to the mating flange, the sealing surfaces are not pareallel to EACH OTHER, or
2. The sealing surface of each flange itself is not flat, but "wavy" or "warped", or
3. Something comletely different.

   Finally...are there any ASME spec's regarding allowances or    tolerances for A. or B.
