ABSTRACT:
Method and apparatus for repair of a tubular fluid-containing vessel such as a pipe or hose. A repair patch includes a sheet of heat-shrinkable material and take-up means for tightly securing the sheet to itself around the pipe or hose. The method includes placing the sheet of heat-shrinkable material around the tubular vessel, taking up the two ends of the sheet relative to each other until the sheet is wrapped snugly around the pipe or tube, and applying heat to the heat-shrinkable sheet to shrink the sheet tightly around the pipe or hose and seal the leak.
