B31.3 External Pressure + Thermal Stress Limits?
B31.3 External Pressure + Thermal Stress Limits?
(OP)
Per B31.3 the limits of max. code stress = Sustained Loads+ Displacements Loads & When Sh>SL then,
Max. Code Stress = f[1.25(Sh+Sc)-SL] or
Sa + SL = f[1.25(Sh + Sc)]
What Sa + SL would be if we have external pressure? Algor pipePlus solution for 304 SST (Sc =Sh = 20,000 psi)& f =1
is 25,000 psi? Why is that?
Thank you,
Jay

There are no rules in B31.3 for structural stability checks: ASME VIII Div.1 should be used.
