SPECTACLE BLIND

 

Spectacle Blind Flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectacle flanges are named for their resemblance to a pair of reading glasses, or spectacles. Spectacle flanges, also known as spectacle blind flanges, are most commonly used on piping systems that need to be separated regularly or where the flow through the systems is regularly stopped. One end of the spectacle flange is solid, while the other end has a hole in the center. By rotating the spectacle flange, either the solid or hollow end can be positioned within the pipe system, thereby opening or closing the flow. Spectacle Blind Flanges are available in RF/FF design to be inserted between flanges with flat seals or spiral wound gaskets. They are also available in RTJ design male or female versions to be inserted between corresponding flanges.
