I need help. I'm a lowly construction manager with a difficulty. I have a piping system whose components are carpenter 20 and I need b-464 fittings. I can order all of the above but need guidance in quality control.
I can a capable and honest contractor so I'm not concerned about results but would like to talk with some technical person that can help me verify my needs relative to welder quals and tests.
I think that 20 cb-3 is nickel based, as the B-464 specs reference but cannot remenber.
Any help would be appreciated.
Thanks
Mark
