RE: about mil tolerance

For the ASME to respond to this kind of query may be a little bit of an overkill. Here's some of my suggestion.

Check out.
B36.10 for Carbon Steel pipe
B36.19 for Stainless Steel pipe

Or the Pressure/Stress ratios for determining the required wall thickness from Piping Engineering. Ive got the 1979 issue by Tube Turns.

Or Table P-1, Pipe Data from Piping Guide by Sherwood/Whistance.

Or you may want to visit the ASME website. John Breen has spoken something about this subject in the Forum.

Or The article that appeared on TheFabricator.com (Aug 2003) about the min. wall thickness variation may interest you.

Goodluck.
