<p><P>PROBLEM TO BE SOLVED: To provide a connection part forming tool for a fluid pipe and connection part forming method using it capable of forming the connection part for connecting the fluid pipe to a connection body by suppressing the load acting on the end part of the pipe body to the minimum. <P>SOLUTION: The connection part forming tool 11 forms the connection part S for connecting a water passing pipe 10 consisting of the pipe body 10a to a joint on the end part of the pipe body 10a. The connection part forming tool 11 is equipped with a draw-out body 13, and a diameter expanded part 13a having the larger diameter than the inner diameter of a ring body 12 made of metallic material is formed on the draw-out body 13. By passing the draw-out body 13 inside the ring body 12 and drawing out it from the pipe body 10a, the ring body 12 is expanded from the inner side by the diameter expanded part 13a and the connection part S is formed on the end of the pipe body 10a. <P>COPYRIGHT: (C)2004,JPO</p> |
