Abstract
A leak repair clamp for pipe and pipe flanges includes a frame having a plurality of segments positionable in end-to-end relation around the pipe. Each segment includes spaced parallel annular lips flaring from its inner periphery with each lip being an integral part of the segment and having a bent tip portion extending toward the matching oppositely positioned tip portion of the opposite lip. A connecting means is used to connect the segments together in end-to-end relation, the lips extending from the segments to thus form an annular recess around the pipe when the segments are connected. An access means is provided in the frame to permit passage of a liquid sealant into the recess and the lips direct flow of the sealant into direct contact with the pipe to form a self-energizing seal between the lips and pipe.
