Blind Flange

Blind Flanges, which are manufactured without a bore and have no holes in the center to seal the pipe opening, are well suited for high temperature and pressure applications. They are used to blank off the ends of pipes, valves and pressure vessel openings. Like a flange cover, also called a blind disk or flanged pipe plug, the function of a blind flange is the same as a pipe plug or pipe cap. The difference is that the blind flange is a detachable equipment, making it easy to replace or do maintenance.

A blind flange is a solid steel piece with no bore (interior diameter) and primarily designed to cap off a line. As the majority of flange connections allow for the passing through of air or fluid via an interior opening, blinds give the ends of pipe connections a well formed termination point or rerouting of the media in question towards another portion of the pipe assembly. Opt for a blind flange in these cases, as well as in instances when a pipe line requires a future modification such as the installation of a valve or fitting to reroute flow.
