PROBLEM TO BE SOLVED: To provide a tube part repairing hardware capable of partly repairing a pipeline almighty by using a long lining material from a short lining material and a method for repairing a tube part. SOLUTION: The method for repairing a tube part comprises the steps of first introducing a tube part repairing hardware 15 into a pipeline 20 in the state that its pressure bag 5 is contracted, setting it to a predetermined position, and then supplying compressed air (pressure fluid) into the bag 5 of the hardware 15 to expand the bag 5. The method further comprises the steps of heating a lining material 1 by warm water (heating medium) supplied into the bag 5 while the material 1 remains pressed to the inner peripheral wall of the pipeline 20 by the bag 5 to cure the thermosetting resin immersed thereinto, then extracting the compressed air and the warm water in the bag 5, and pulling a warm water suction hose 12 to remove the material 1 from the bag 5.
