FAQ
- What does ASME B16.5 cover for high-pressure stainless flanges?
- ASME B16.5 covers flanges from NPS 1/2 to NPS 24 for pressure classes 150 through 2500, with Class 2500 limited to NPS 12 and smaller . It specifies dimensions, pressure-temperature ratings, materials, tolerances, marking, and testing for forged or cast flanged components .
- How do pressure classes and temperature affect the rating of stainless flanges?
- The standard provides pressure-temperature (P/T) tables for 35 material groups . For example, an ASTM A182 F316L flange (Group 2.3) is rated at 230 psig at 100F, but its allowable pressure decreases to 600 psig for Class 300 at 500F-pressure drops as temperature rises . Linear interpolation between listed temperatures is permitted .
- What are the common flange facing types and when are they used?
- Raised Face (RF) is the default for most stainless process piping (Class 150: 1.6mm height; Class 400+: 6.4mm) . Ring Type Joint (RTJ) is specified for high-pressure/high-temperature Class 600-2500 services, using metal ring gaskets . Flat Face (FF) is typically limited to low-pressure Class 150 applications with cast iron mating flanges .
- What mandatory markings are required on ASME B16.5 flanges?
- Each flange must be permanently stamped with: (1) manufacturer's name or trademark, (2) ASTM specification and material grade (e.g., A182 F316L), (3) pressure class number, (4) "B16" indicating standard conformance, and (5) nominal pipe size designation .
