Product Description

Duplex Stainless Steel Spectacle Blind Flange

Generally, spectacle blinds are in the open position so that fluid can pass through the pipe. When the spectacle blind is in the closed position, the pipeline is closed and the fluid is blocked.The maintenance of the piping system is one reason why the spectacle blind rotates to the closed position. There is a drill hole in the connecting web of the spectacle blind. Loosen and disassemble some bolts. The spectacle blind can rotate between flanges. After replacing the gasket, the bolts can be reassembled and tightened.
