PIPE ATTACHMENT STRUCTURE AND PIPE ATTACHMENT METHOD

摘要

To provide a pipe attachment structure and pipe attachment method, capable of making workability excellent in attaching a pipe, and firmly fixing the pipe after attachment.SOLUTION: A pipe 10 penetrates through an insertion port 15 of a clamp 14. A middle portion of the pipe 10 is molded into a bellows shape, to form a protrusive deformation part 11. Also, an inner wall of the insertion port 15 of the clamp 14 is formed into a bellows shape. When the inside of the pipe 10 is made into a high-temperature and high-pressure state, the protrusive deformation part 11 protrusively deforms, and then is fitted to the inner wall of the insertion port 15 of the clamp 14, so that movement in an axis direction of the pipe 10 is regulated.SELECTED DRAWING: Figure 3
