Spectacle blind flange (also frequently referred to as a figure-8 blind or spectacular blind via patented variations).Design & FunctionThe Structure: It is a critical piping safety component composed of two metal discs joined by a small web or bridge, closely resembling a pair of eyeglasses.Dual Purposes: One half is a solid metal disk (the blank/blind) designed to completely block fluid or gas flow during system maintenance. The other half is a hollow ring (the spacer) possessing an inner diameter equal to the pipe, which allows normal process flow.Operation: It is permanently installed between two pipe flanges. To transition states, operators simply loosen the flange bolts, rotate the plate 180 degrees to switch from open to closed (or vice-versa), change the gaskets, and retighten the bolts
