Can someone explain to me how effective the procedure outlined in ASTM E837 is at determining residual stress in a heavy wall pressure vessel?
The situation I have is that a fabricator is proposing to do this test on a recently in-service vessel to determine if pre-heat is necessary prior to making modifications to a vessel. Is this procedure good at determining stress throughout the thickness of the wall or just the surface stress?
