Flange classes and pressure ratings
WebThe pressure ratings change based on the material from which it is made and/or the temperature at which it operates. The nominal flange Class (e.g., Class 125) generally represents the maximum working pressure at the temperature of saturated steam at that pressure. For example, an ANSI/ASME B16.1 Class 125 flange is rated for 125 PSI at … Webpressure‐temperature ratings for all materials and all pressure classes as a measure to conserve vital materials in piping components.
