ABSTRACT:
Disclosed is a pipe repair sleeve apparatus. There is a draw means having expanding means on either end of the draw means. There is also an annular repair sleeve. The draw means is contained within the sleeve with at least a portion of each of the expanding means protruding outside of the sleeve. Then, the repair sleeve assembly is inserted within the damaged pipe. The draw means urges the expanding means toward one another and inwardly of the sleeve so that opposed ends of the sleeve are expanded outwardly into engagement with an inside diameter of the damaged pipe. Preferably, the draw means is made from a material which is a shape memory alloy. Also disclosed is a method of repairing a damaged pipe. This method specifies the steps necessary for installing the pipe repair sleeve apparatus.
