A blind flange is a round plate which has all of the relevant blowholes except center hole, and because of this feature the blind flange is usually used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.
Without the blind flange it would be difficult to perform maintenance or repairs on a pipeline. Blind Flanges are widely used in the petrochemical, pipe engineering, water treatment etc.
