Abstract
A system for repairing a pipe damaged with dents includes a pipe holding device, a mandrel, a cable, and a winch. The pipe holding device is for holding the pipe in position. The mandrel, with a cross section and size adapted to be pulled through the interior of the pipe, has a first edge, a second edge, and a side surface. The cable has first and second ends, and the first end is detachably attached to the first edge of the mandrel. The winch is connected to the second end of the cable for winding up the cable. The mandrel is pulled by the winch with the cable and travels through the pipe to push out from inside and remove the dents on the surface of the pipe.
