A spectacle blind flange is a type of piping component used in pipelines, typically in high-pressure or high-temperature applications. It consists of two metal discs attached to each other with a solid section in the center, which can be rotated to align with one of the two flanges.

The purpose of the spectacle blind flange is to isolate or block the flow of fluid in the pipeline. When the solid section is rotated to align with the flange, it creates a solid barrier that stops the flow of fluid. Conversely, when the solid section is rotated to align with the second flange, the flow of fluid can continue.

Spectacle blind flanges are commonly used in situations where there is a need for periodic maintenance or inspection of the pipeline. They can also be used to prevent contamination of the fluid being transported or to divert the flow of fluid to an alternative pipeline. They are available in a range of sizes and materials to suit various pipeline applications.
