Alloy Steel Spectacle Blind Flanges are manufactured, exported, and supplied by Rajendra Industrial Corporation, a prestigious manufacturer, exporter, and supplier. We use the best minerals available on the market to create our products. We use tools and technology from the area to make our products. We sell Alloy Steel Spectacle Blind Flanges at a low price because we are one of India's most recognized suppliers. Alloy Steel Spectacle Blind Flanges are like a pair of glasses and are therefore named spectacle blind flanges. They are like two metal discs joined together by a section of metal to form the flange. These flanges are also popularly known as ‘figure8 flanges.’ The primary role of these alloy steel spectacle blind flanges is that they can easily rotate to open and close the flow from pipes. They are widely used in applications that operate at sub-zero temperatures and are volatile and toxic.
These Chrome Moly Spectacle Blinds are usually installed in an open position, without interrupting the flow of the fluid that has been transferred by the pipeline. Generally, these spectacle blind flanges are available in common diameters which range from ½ inch to 36”. These flanges are available in pressure classes ranging from 150 to 600 pounds while for RTJ flanges, the common pressure range is 300 to 2500 pounds.

The spectacle blind flanges are similar to blind flanges but different because they fit between two flanges. One side of these spectacle blind flanges is totally closed for it to complete the flow completely shut off, whereas the other end is open for full flow. Our products are put through a series of testing to verify that they are of high quality, safe, and long-lasting. All our products are made with extreme care and precision. These Alloy steel spectacle blind flanges are widely used in plumbing, water supply systems, heating and many more.
