What Is a Spectacle Flange
A spectacle flange, also known as a spectacle blind flange, is a piping component used to completely stop or allow the flow of a fluid through a pipeline. It consists of two parts: a solid blind section and an open ring section connected by a small web.
The open section allows normal flow through the pipeline, while the blind section blocks the flow when isolation is required. The component gets its name because its shape resembles a pair of spectacles.
Instead of completely removing a blind flange whenever isolation is required, a spectacle flange can be rotated to change between the open and closed positions. This makes it a practical solution for pipelines where regular isolation is necessary.
