<p>PROBLEM TO BE SOLVED: To provide a flexible Hume pipe whereby labor required for work at laying time is decreased as far as possible, work man hours and a cost at laying time can be reduced. SOLUTION: In a flexible Hume pipe 10, relative movement of a front/rear pipe part 11, 26 can be performed. In a rear end periphery of the front pipe part 11, a guide sleeve 13 and a first collar 15 arranged in an annular recessed part 12 are fixed. In a front end periphery of the rear pipe part 26, an annular recessed part 27 and a seal material 23 are provided. A cylindrical second collar 22, fit mounting a front end side able to advance/retract between a first collar 15 and a guide sleeve 22, extends a rear end side from the first collar 15, a rear end internal peripheral surface is brought into press contact with the seal material 23, to be connected to the rear pipe part 26. In a location covered with the first collar 15, a total periphery of the front end part is fixed to the guide sleeve 13, a bellows pipe 20 fixed with the total periphery of the rear end part to the second collar 22 to have extending/contracting flexibility is arranged.</p> |
