    Fatigue Crack Growth Eqns in API 579

    chicopee and DVWE, thanks for the input. I obtained the spec for SA-302 in ASME Sec. II, and it is a type of alloy steel. The plate is just over 3 inches in thickness so it is normalized as DVWE said. So just to understand, in order to get a martensitic microstructure, it would have to depend...

    Fatigue Crack Growth Eqns in API 579

    Hello all, I had a particular question concerning the fatigue crack growth data listed in Appendix F of API 579-1/ASME FFS-1 (2007 ed). I am analyzing a pressure vessel constructed out of SA-302 Gr. B (mod.) material with a yield strength (Sy) of 100 ksi. Typically we use the Paris Law to...

    L-shaped pressure vessel

    Thx for replying jte, but it's not quite like in the previous thread you mentioned. The pressure vessel itself has a rectangular cross-section, but is configured in an "L" shape, not simply vertical or horizontal. It is a specialized hydraulic reservoir and is not code-stamped. I believe VIII-2...

    L-shaped pressure vessel

    Hi there, Is there any ASME code or other standard out there that talks about L-shaped pressure vessels? I know that Section VIII Div 1 Appendix 13 covers non-circular vessels, but none of the geometry matches to what I am analyzing, which is an L-shaped hydraulic cart that sits on a platform...
