Identifies the ANSI B16.5 or API 605 flange rating, (class).

  • B16.5 valid classes are 150, 300, 400, 600, 900, 1500, and 2500

  • API 605 valid classes are 75, 150, 300, 400, 600, and 900

B16.5 specifications govern up to and including 24-inch pipe. API 605 specifications govern nominal pipe sizes 26- though 60-inch.

Use the flange rating entry to access the B16.5 or API pressure/temperature rating table. The software includes minimum and maximum allowed ratings for all different materials available in the tables. You can see minimum and maximum computed allowed equivalent pressures and safety factors in this data. API 605 does not have minimum and maximum data. The minimum and maximum data is the same when the nominal English pipe size is greater than 24-inches.
