ABSTRACT:
A method of repairing a heat exchanger comprising a housing within which a plurality of spaced apart tubes extend. The method comprises the steps of, once a leak in one of the tubes has been detected, sealing the defective tube at both ends, cutting the defective tube adjacent the ends, removing the tube and mounting a body of suitable shape in its place, thereby ensuring that a proper temperature distribution occurs in the vicinity of the body during operation of the heat exchanger.
