Overview ANSI B16.5 Forged Flange Classes

The standard ANSI B16.5 Flange Dimension doesn’t technically exist; it is a defining standard for pipe safety since 1922. It covers both the pipe flanges and flanged fittings. The size ranges from NPS ½ through NPS 24 metric/inch standard.

ANSI B16.5 flange Din En 1092 is produced in rating classes with the following designations:

  • 150
  • 300
  • 400
  • 600
  • 900
  • 1500
  • 2500
