Hi all,
A client of mine has two ASME VIII stamped pressure vessels made by different companies in the 60s.
Both are made of SA-7 and what puzzles me is the Tensile Strength on each vessel is 55k but the code says there is a 0.92 quality factor thus giving an allowable stress of 12,650 psig.
My clients are swearing up and down that the quality factor doesn't apply until later years and the allowable stress should be 13,750 psig.
Thoughts?
