Abstract
PURPOSE: To provide an effective repairing of a heat transmitting fine pipe inserted into a tubular plate of a heat exchanger by a method wherein a thin valled inner cylinder formed with an annular projection at its outer one end surface is inserted into the leading end of the heat transmitting fine pipe, expanded therein, and sufficiently closely adhered to the heat transmitting fine pipe partially expanded.
CONSTITUTION: Corrosion of a heat transmitting fine pipe 5 inserted into the tubular plate 1 and adhered thereto and a position of the breakage 15 are sensed, and a length of the sleeve 20 is defined in response to the sensed position. Outer surface at one end of the sleeve 20 is formed with annular projections 21, 22. The sleeve 20 is inserted into the fine pipe 5 with its one end having projections 21, 22 being faced inwardly and then the pipe is expanded. The projections 21, 22 are encroached upon the inner surface of the fine pipe 5 and sealed. Then, a closing welding 25 is applied between the other end of the sleeve 20 and the inner surface of the fine pipe 5.
