Abstract

PURPOSE: To facilitate the repair of a tube by cutting the defective part of the tube, attaching solder collars to the cut ends, disposing an adapter attached with the shoulder collars to both ends between these ends and connecting the tubes by halved housings.
CONSTITUTION: The defective part of the tube with which leakage arises is cut away and the fins 11 near the cut ends 15 of the remaining tubes are removed. The shoulder collars 16 are fitted to the outer peripheries of the respective cut ends 15. Further, the angle parts formed between the cut ends 15 of the tubes and the inner peripheral surfaces of the collars 16 are subjected to fillet welding 7, by which the collars 16 are fixed to the cut ends 15. The adapter 19 formed by welding the collars 16 to both ends of a fresh finned tube 18 is prepd. and an annular packing 20 having a C shaped section is fitted onto the collars 16 fixed to the remaining tubes 6 and is inserted to the part where the adapter 19 is removed that the packing 20 spans between the collars 16. The halved housings 21 are put thereon and the end parts of the housings 21 are bolted to connect the tube.
