Detailed Information

What is a spectacle blind?
Spectacle Blinds are simple safety devices that are put between two pipe flanges. During normal use, the open end is set up as a spacer to keep the flow from being interrupted. The flow in the pipeline is stopped by moving the blind end between the flanges.

Prashaant Steel & Alloys is known as the pinnacle in the world of metal market for the best quality Spectacle Blind Flange production in India. We can produce Spectacle Blind Flange according to the standards for materials, pressure ratings, etc. Such standards include DIN, BS, and/or ISO standards, Japanese JIS. Spectacle Blind Flange is a flange placed over the end of the pipe that extends the flange face from the end of the pipe by a sufficient distance to remove a soiling Perle on the internal diameter. Also on the back of the flange, the outer diameter of the flange is soldered. Flanges are less costly than Spectacle Blind Flange and easy to fit. Often, if type B or type C ends are used, this can be used as Spectacle Blind Flange.
