<p><P>PROBLEM TO BE SOLVED: To ensure more complete corrosion prevention in a mounting frame of a pipe, and to enable non-destructive inspection of a contact portion between the pipe and the mounting frame from outside even after pipe installation. <P>SOLUTION: The pipe installing structure 1 includes the pipe made of metal more precious than zinc, and the mounting frame for supporting thereof. A low-friction member 7 is arranged fixedly on the mounting frame 4 between the pipe 2 and the mounting frame 4. A corrosion prevention member 3a made of a zinc or zinc alloy plate is arranged between the pipe 2 and the low-friction member 7 so as to directly contact the pipe 2, and slide against the low-friction member 7. When the corrosion prevention member 3a is thermally expanded and contracted, the low-friction member 7 has such a sufficient low-friction coefficient that the corrosion prevention member 3a slides relative to the low-friction member 7. Between the low-friction member 7 and the mounting frame 4, a second corrosion prevention member 3b made of a zinc or zinc alloy may be arranged fixedly on the mounting frame 4. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
