Terminal structure of gas transportation for the flexible tube

摘要

PROBLEM TO BE SOLVED: To provide a termination structure of a gas transport flexible pipe suppressing permeation of gas to the outside of the flexible pipe, light in weight, and superior in flexibility, even when used in middle-pressure A to high-pressure conditions.;SOLUTION: In a gas piping termination structure 1, a protection layer 21 and a reinforcing layer 19 in a prescribed range of an end of gas piping 3 are peeled. A termination member 23 is joined to an end of a pipe 15. A fixing member 5 is provided at an outer circumference of the joining part so as to cover the joining part of the pipe 15 and the termination member 23. An end at a rear side of the fixing member 5 is provided with an O-ring 25 at an inner circumferential surface side of the fixing member 5 so that it is in contact with the outer circumference of a shielding layer 17. An end at other side of the fixing member 5 is provided with a flange 7. The flange 7 protrudes in a radial direction, and is in contact with a rear surface side of a flange 24 of the termination member 23. The front surface side of the flange 24 is provided with a packing 11.;COPYRIGHT: (C)2012,JPO&INPIT
