Abstract
A self-energizing seal includes a housing and a plurality of annular seal ring segments movable relative to the housing. The annular seal ring segments include a circumferential slot and a plurality of holes defining a flow passage into the circumferential slot. A plurality of self-energizing ring segments are disposed in the circumferential slot. The annular seal ring segments and the self-energizing ring segments establish a seal with the exterior of a pipe and permit movement of the pipe in a direction orthogonal to the axis of the pipe.
