Spectacle Blind Flange
The ASME B16.48 is a standard that takes into consideration such as materials, dimensions, pressure-temperature ratings, tolerances, marking, as well as testing for flanges such as piping spectacle blind flange in a piping system. A Spectacle Blind flange is typically used to permanently separate piping systems, or they could be used to form a connection with each other. A Spectacle Blind Flange Manufacturer cuts two discs from a steel plate of a certain thickness. These two discs are appended to each other by section of steel in such a manner that they visually appear similar to the nose piece of a pair of glasses. Hence, this flange is referred to as a spectacle flange. While one of the discs in the flange is a solid plate, and the other disk is a ring, whose inside diameter is equivalent to that of a flange.

A Stainless steel spectacle blind flange could be used in applications for those piping systems, which regularly have a requirement to be separated or unconnected from other installations. Typically, this flange is mounted in an open position which promotes the flow of media through the pipe is possible. In the instance of the carbon steel spectacle blind flange being in a close position, the pipe is blanked off by rotation, leading to no flow. A reason to rotate the flange in the close position is due to maintenance in a piping system. This run will take place through the hole, that has been drilled in the connection piece. When all the bolts have been loosened, the ASME B16.48 Spectacle Blind Flange can be rotated. After the old gaskets have been replaced by new gaskets, the bolts could be re-assembled and tightened.
