I have a pretty simple question.
I have a Design Temp of 70degC (158degF). When obtaining the Max allowable stress from table A3 in B31.1 can I interpolate to get S at my design temperature.
ie.
From -20 to 100F S= 16700psi
Up to 200F S= 14300psi
Can I interpolate and use S= 15308psi?
Or do I have to use S= 14300psi?
