  • Hi, I'm looking into modelling some ABS piping, for the allowable stress (using ASME B31.3) would you recommend using 0.32 x HDS x Temp De-Rating or base the allowable stress of the pipe on manufacturers allowable span/deflection limits (as per COADE Mechanical Engineering News April 1991/Ulu Pandan Stress Analysis Report - MF Feed System)? Thanks in advance.
