Dual Rated Pipe & Fittings
Dual Rated Pipe & Fittings
(OP)
Whenever we receive pipe & fittings dual rated as "316/316L", for example, does that ALWAYS mean that the allowable stress will be the HIGHER rating of the two? The pipe distributor said it's true & I looked at a few MTR's and the mechanical test Tensile Strength & Yield Strength were the higher values. I need to know if I can go ahead and design base on the higher value.

By the way, I am in the unenviable position of verifying the Code conformance of a design that's been in use for 50 years but evidently no one ever actually qualified it. So I sincerely want to be able to show that the legacy design is safe.
