SPECTACLE BLIND FLANGE
Spectacle Blind Flanges are specialized components used to either stop or allow the flow in a piping system. They consist of two metal discs—one solid (the blind) and one with a bore (the spacer)—connected by a small piece of metal to form a figure-eight shape. By rotating the spectacle blind between the flanges, the pipeline can be opened or closed without removing the flange connection.
Manufactured from high-quality materials such as carbon steel, stainless steel, and alloy steel, Spectacle Blind Flanges are available in various sizes, pressure ratings, and international standards. They are commonly used in oil & gas, petrochemical, power generation, and offshore industries where reliable flow control and safety are critical.
