WebAug 28, 2024 · The service temperature of flanges decreases as the temperature increases, but this has no real correlation with pressure class. In fact, different materials rated in specific classes react differently as the temperature changes. In general, ANSI class is similar to PSI and the pressure rating can be expressed as either an ANSI class or psi. http://www.metalspiping.com/working-pressures-for-ss-304l-316l-flanges.html
Pipe Class Ratings vs. Pressure Numbers (PN)
WebApr 18, 2024 · The pressure rating of flange ranges from 150# to 2500#. The term "lb", "class" and "#" are used interchangeably to designate the pressure rating of the flange.
