A specific type of flange called a spectacle flange is constructed from two metal discs joined together in the center by a thin piece of steel. Because they resemble a pair of reading glasses or spectacles, spectacle flanges are so named. The most typical application for spectacle flanges, also known as spectacle blind flanges, is on piping systems that need to be routinely separated or where the flow through the systems needs to be intermittently interrupted. The spectacle blind flange has a hole in the middle on one end and a solid end. By rotating the spectacle blind flange, the flow can be opened or closed by positioning either the solid or hollow end inside the pipe system.

Advantages of Spectacle Flanges
- Installation of spectacle flanges does not require welding.
- A variety of pressure tolerances are available for spectacle steel flange.
- There are several diameters of spectacle steel flanges.
