Ratings for ANSI Class 1flanged end valves end at 1000ºF. Piping Class Ratings based on ASME B16. A Class 3flange is rated to a higher pressure than a Class 1flange, . A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam.

These pressure classes also have differing pressure and temperature ratings for different materials. Each specification further delineates flanges into pressure classes: 15 30 40 60 90 15and 25for B16. Difference between class 15 36Flange. The Pressure Class or Rating for flanges will.
