<p>PROBLEM TO BE SOLVED: To provide an anticorrosion device which unfailingly restricts movement of an anticorrosion ring without affecting the accuracy of the corrosion prevention.SOLUTION: An anticorrosion device 11 includes: an anticorrosion ring 1 which is attached to a pipe end part of a fluid pipe 2 and covers a pipe end surface 2a to achieve corrosion prevention; a protection tool 12 including a front surface plate 12a which covers a front surface of the anticorrosion ring 1, a side surface plate 12b which covers an outer side surface of the anticorrosion ring 1, and a pressing part 12c which is pressed against an outer peripheral surface of the fluid pipe 2, the protection tool 12 covering the anticorrosion ring 1 to protect the anticorrosion ring 1; and fixing means 13 which presses the pressing part 12c to fix the pressing part 12c. When the anticorrosion ring 1 is attached to the pipe end part and the protection tool 12 is disposed at the pipe end part to be fixed by the fixing means 13, the side surface plate 12b and the anticorrosion ring 1 are disposed so that a clearance is disposed at least between the side surface plate 12 and the anticorrosion ring 1.</p> |
