Pressure ratings are based on ASME Code for Pressure Piping B31.3, Process Piping with allowable stress 20,000psi for SS316,10,000psi/Brass, and 20,000psi/ Carbon steel.To determine pressure ratings in accordance with B31.1, Power Piping:- 316 Stainless steel material : multiply by 0.94, Carbon steel material : multiply by 0.75, Brass material ratings remain the sameTo determine kPa, multiply by 6.89
