Pressure-Temperature Rating Lookup
Look up the maximum allowable working pressure (PSIG) at a given service temperature for ASME B16.5 flanges. Choose a material group, pressure class, and temperature to interpolate between published rating points.
Inputs
Maximum Allowable Working Pressure
At 100 F for Class 150, Group 1.1 - A105, A350 LF2, A516-70 (Carbon Steel).
Disclaimer: Values reflect a simplified interpolation of common ASME B16.5 rating tables. For final design and code compliance, use the latest published edition of ASME B16.5 and confirm material group assignment from the actual heat MTR.
For background on flange pressure ratings, see our pressure ratings guide.
