ABSTRACT:
To facilitate the repair of short sections of pipe by providing a lining in situ, a repair carrier containing the repair lining is moved into position adjacent the pipe length to be lined, the lining is forced out of the carrier into position in the pipe where it is fixed in position and the carrier is then removed from the pipe leaving the lining in place. A flexible tube forming a part of the carrier is used to initially position the lining in the carrier and then to force the lining out from the carrier and urge it against the interior of the pipe, preferably by eversion.
