Abstract
System for pipeline rehabilitation. The system includes repairing a leak in a pipe using a pair of substantially semi-cylindrical parts connected through a compliant joint. When the parts are compressed, the semi-cylindrical parts form a cylinder whose outside diameter is less than the inside diameter of a pipe with a defect thereby allowing the cylinder to be inserted into the pipe at a location of a leak. Once in place, the parts engage the inside surface of the pipe when the compression is released thereby to seal the leak.
