Applicable Standards

Standards governing design, dimensions, and testing

ASME B16.5

Pipe Flanges and Flanged Fittings: NPS ½ Through NPS 24

The global standard for pressure-rated flanges. Defines seven pressure classes (150 through 2500) with pressure-temperature ratings for multiple material groups.

  • Pressure classes: 150 / 300 / 400 / 600 / 900 / 1500 / 2500
  • P-T ratings vary by material group and temperature
  • Carbon steel A105 (Group 1.1) @ 38°C: Class 150 ~20 bar, Class 300 ~51 bar; stainless and alloy groups rate differently
  • Raised Face (RF) is the standard facing type
  • Ring Type Joint (RTJ) for high-pressure critical service
  • Bolt torque and gasket requirements are user's responsibility
