<p><P>PROBLEM TO BE SOLVED: To securely release high-pressure fluid flowing in a gap between an outer layer tube and an inner layer tube out through various routes. <P>SOLUTION: A pipe joint is mounted to an end part of a hose 12 having an outer layer 14, an inner layer 16, and a fiber reinforcement layer 18 sandwiched between them. The pipe joint has: a connector 40 for inserting a diameter-enlarged part 42 to the end part of the hose 12 and having a butting part 44 fitted to a joint bolt; a joint nut 36 pressing the end part 20 of the hose 12 to the diameter-enlarged part 42 of the connector 40; and a joint bolt 24 including a penetration hole 35 for passing fluid flowing in the hose 12, a small diameter part 30 coaxially continuing to the penetration hole 35 for accepting the butting part 44 of the connector 40, and a large diameter part 32 for accepting the end part 20 of the hose 12 inserted with the connector. The joint bolt 24 is provided with a relief groove 48 formed from the small diameter part 30 to reach the large diameter part 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
