About the blind flange
A blind flange closes the end of a flange connection. Unlike a welded end cap, it is bolted and can be removed for access, cleaning, or future connections. Standard at vessel nozzles, test points, and inspection ports.
Applicable Standards
Standards governing design, dimensions, and testing
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
