Alloy 20 Spectacle Blind Flange is a pipe fitting consisting of a blind flange at one side and a iron ring at the other side.

Alloy 20 Spectacle Blind Flange is generally applied to permanently separating pipesystems, or just to connect with each other. A Spectacle Blind Flange 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.
