What Is Blind Flange?
Blind Flanges, often called Blank Flanges, are those whose objective is to close-block ends in a pipe line, valves or container openings, subjected to various working pressures. Blind Flanges totally block flow in a line, are widely used in high pressure applications. Actually the Blind Flanges is used to close the endings of piping systems and the opening of the pressure vessels. Once a line or container has been sealed and must be reopened, workers can easily remove the blind flange to access to the inside. There is no hole in the middle of the flange cover of the blind plate, which is used to block the pipeline. The difference between the blind flange and the end socket is that the blind flange is a removable seal plate, and the end socket is a kind of seal plate that directly welded to the pipe and cannot be removed. Technically, the Blind Flanges support the most severe working conditions (especially those with larger diameters), since the effort caused by the existing pressure in the pipe is added to the effort caused by the tension of the bolts.
