Manufacturer/Exporter Of High Spectacle Blind Flanges
Stainless Steel Spectacle Blind Flanges, Alloy Steel Spectacle Blind Flanges Manufacturer & Exporter.
Spectacle Blinds are generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind is a steel plate cut into two discs of a certain thickness.
The two discs are attached to each other by section of steel similar to the nose piece of a pair of glasses. One of the discs is a solid plate, and the other is a ring, whose inside diameter is equal to that of a flange.
The wide range of Spectacle Flanges offered by us is available in quality stainless steel and alloys. These Flanges is available in various size, grades, Specification & thickness as per the clients requirments. These flanges widely used in various application industry like waterworks, petrochemicals, refineries, chemical industry and construction works etc.

Spectacle Blinds be applied in systems, which regularly need to be separated from other installations. Normally, a Spectacle Blind is mounted in the "open" position so that flow through the pipe is possible. If the Spectacle Blind in the "close" position is rotated, the pipe is blanked off and no flow is possible.
Maintenance on a pipesystem can be a reason to rotate the spectacle in the "close" position. This run will take place through the hole, that is drilled in the connection piece. By loosening of all bolts, and partial removal of their, the Spectacle Blind can be rotated. After replacing the gaskets (new gaskets are to recommend), the bolts can be re-assembled and tightened.
