PROBLEM TO BE SOLVED: To provide an anticorrosion ring capable of performing anticorrosion treatment work of a pipe end surface of a fluid pipe by the anticorrosion ring in a short time, and improving anticorrosion effect by increasing pressing force to the pipe end surface, of an anticorrosion portion of the anticorrosion ring.SOLUTION: In an annular anticorrosion ring 5 having an anticorrosion portion 15 for preventing corrosion by pressing a pipe end surface 3b of a fluid pipe 3 composed of a magnetic material, and a holding portion 16 for holding the anticorrosion portion 15 with the pipe end surface 3b, the holding portion 16 opposed to the pipe end surface 3b of the fluid pipe 3 is provided with a permanent magnet 18 for pressing the anticorrosion portion 15 to the pipe end surface 3b side by magnetic force. |
