ABSTRACT:
The present invention provides a pipe tool for repairing a damaged section of a pipeline. The repair tool comprises a main body having a top surface and a bottom surface. A compressible alignment portion is positioned above the main body. A compression plate is positioned above the alignment portion. An elongate rod extends through the center of the main body, the alignment portion and the compression plate. A fastener is secured to the top end of the compression rod and a rotatable fastener is secured to the bottom end of the rod. The repair tool is inserted into an open end of a cut pipe so that the top surface of the main body aligns with the open end of the pipe. The alignment portion is then compressed by rotating the rotatable fastener to secure the pipe repair tool inside of the cut pipe.
