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.
