ASME B16.5 working pressure ratings as a function of material, class, and service temperature. The numbers that matter when matching a weld neck flange to a line spec.
Max Working Pressure
285 psig
A105, Class 150, at 100°F
Reference values per ASME B16.5. Actual project ratings should be verified against the full P-T table for the specific material grade and design temperature. NACE, low-temperature impact, and sour service may impose additional limits.
