About Spectacle Blind Flange

A Spectacle Blind Flange (also known as Figure-8 flange) is a safety device used to either isolate a pipeline or allow flow. It consists of two metal disks joined by a web one side being a solid blind plate, the other a ring spacer. By rotating the spectacle blind, the pipeline can be blocked (blind side) or kept open (spacer side). Induskart provides forged spectacle blinds in Carbon Steel, Stainless Steel, and Alloy Steel, manufactured as per ANSI B16.48 standards for reliability and safety in industrial operations.
