A method for sealing leaking pipes in heat exchangers, comprising the installation, after detection of a leak and determination of the leaking pipe, of extension pieces on the two ends of the pipe, the severing of the pipe adjacent one end and the cutting of openings in the pipe wall adjacent the other end. Subsequently flow conductor tubes are inserted in the two ends of the pipe, and sealing caps are installed on the extension pieces. In operation the pipe is now entirely traversed by the liquid that normally flows around the non-defective pipes. The creation of so-called dead spaces (i.e., stagnant regions) is thus avoided. |
