Blind flange

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. The flow would need to be s

hut off at the nearest valve, which could be miles away from the repair area. Valves are also very expensive and are prone to sticking. The blind flange is a much more cost efficient way of sealing a pipe.
Blind Flanges are commonly used in petrochemical, pipe engineering, public services and water treatment etc.
