SPECTACLE BLIND FLANGES

A section of line or piece of equipment that needs to be taken out of service is separated using spectacle blind flanges. It is a steel plate that divides two discs into two different sizes, with the ring’s interior diameter matching the flange’s. They are essentially employed to connect two pipes. Carbon steel spectacle blind flanges are easily able to be rotated in order to open and restrict the flow from pipes. They are used in high-pressure pipe networks. There are numerous stainless steel and carbon steel grades and specifications to choose from.

Additionally, we stock Stainless Steel Spectacle Blind Flanges. As a top manufacturer of stainless steel Spectacle blind flanges, we offer these flanges in a variety of stainless steel varieties. Grades 304, 316, and duplex are some of the materials used for flange operations most frequently.
