A Blind Flange is a Flange which has no bore hole and consequently it is used to close the end of a piping system. The Blind Flange is sometimes machined to accept a pipe of the nominal size to which reduction is being made. The Blind Flange reduction can be either threaded or welded. A Blind Flange also allows easy access to a line once it has been sealed.
