<p>PROBLEM TO BE SOLVED: To reduce labor burden, simply and surely repair, and improve mechanical durability. SOLUTION: An anticorrosion layer 2B provided on a metal pipe 2 surface is ground in a part P to be repaired of a metal pipe 2, a coating member 1 being composed of a heat-melting material with a recessed space part 1A formed in a face opposite to the exposed anticorrosion layer 2B, and being formed into such a dimension as forming a clearance S in a space with a side inside of the anticorrosion layer 2B with the exposed one part is mounted on the exposed anticorrosion layer 2B, and the coating member 1 is heated by an ultrasonic wave, so that the outer circumferential edge of the recessed space and the anticorrosion layer 2B oppositely abutting thereon are mutually molten and integrated together. After the melt-fitting, the clearance S is filled with an airtight survey agent DL and the coating member 1 is pressurized from the top so that the state of the airtight survey agent DL is monitored and the melting state of the coating member 1 and the anticorrosion layer 2B is determined.</p> |
