Asme CODE CASE N-62-7 allowable stresses on weak link analysis
Asme CODE CASE N-62-7 allowable stresses on weak link analysis
(OP)
Hi everybody,
I'm reviewing a weak link analysis from an old valve manufacturer. The allowable stresses used to compare with the calculated stresses is based on 0.9 yield strength. For the non pressure retaining itema of the valve. According to my criterium i think that i should respect code case.N-62-7 of Asme. This code case refers the allowable stress to section Ii tables 1a and 1b for comparing stresses.
Am i being too much conservative for using this allowables stresses?

My focus is on valve stockists in the us and uk who supply duplex and super duplex valves, and inconel and hastelloy valves, plus titanium, alloy 20 and 904L valves.
