1.SPECTACLE BLIND TYPES Duplex 2205 Paddle blind Spacer ring spectacle blind
There are three types of spectacle blinds:
- Flat face spectacle blind (FF): similar to a flat face flange, the surface of the disc is flat (suited for flat face gaskets, for low-pressure applications).
- Raised face spectacle blind (RF): likewise raised face flanges, there is an additional thickness on the surface of the disc.
- This type fits semi-metallic gaskets, as the spiral wound type.
- Ring joint face spectacle blind (RTJ): a groove is inscribed on the surface of the disc. This type is used in conjunction with ring joint gaskets.
