Dear all:
My question is how about the stress checking difference between TEE and nozzle.
I just want to limit the checking under elastic scope.

As we know, ASME31.3 can be used for TEE checking, the checking is just for allowable stress that depend on material.
As Nozzle checking, we can use ASME vIII, Division2;

Actually, Tee also is Nozzle, but the ASME31.3's checking in more simple.

who can tell me which one is more conservative between ASME31.3 and ASME VIII division2?

thanks very much!!
