Description:
AÃ? Blind FlangeÃ? is a solid disk used to block off a pipeline or to create a stop. Like a regular flange, it also has mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that aÃ? blind flangeÃ? has no opening to allow fluid to pass through.Ã?Â

A spectacle blind flange is a type of isolation device used in piping systems. It is a forged steel plate that consists of two interconnected discs: a ring with a hole of the same bore size as the pipeline, and a solid disc. In normal conditions, the spectacle blind is installed in the open position and does not interrupt the flow of the fluid conveyed by the pipeline. To stop the flow, the blind end is rotated into place between the flanges.
Spectacle blinds are available in standard sizes up to 24 inches and in forged material grades like ASTM A105 (high-temperature carbon), A350 low-temperature carbon), and various ASTM A182 grades (alloy, stainless steel, duplex). They are typically used in conjunction with flanges, and are available with raised face (RF), flat face (FF), or RTJ faces.
