Hello ,

As per ASME B31.3 ,LTCS material(A333 Gr.6) can be used at -104 Deg. C without impact testing requirements if the stress ratio (Sc) value is (~0.3) as per the graph in ASME B31.3.
My question is do we include the effects of temperature in to consideration while calculating the longitudinal stresses?How do I build the load cases to conform to the code requirements?

Thanks a lot in advance for your answers.
Rajan.
