And, the excessive deformation of the pipe body 11 is suppressed by the axial reinforcing member 32 on the outside thereof. Further, for the same reason as in the first embodiment, the wall thickness of the pipe body 11 can be reduced. Therefore, the rigidity of the pipe body 11 against bending and torsion can be reduced by using a pressure-resistant bending pipe having a normal thickness. It is significantly smaller than the conventional pipe joint device used. As a result, the pipe joint device 10 of this embodiment

こともできる。According to the present invention, the relative displacement of the pipe caused by an earthquake or the like can be tolerated, and there is no unevenness such as a bellows on the inner surface of the joint portion. A joint device that is suppressed and has high strength against internal pressure can be obtained. When the annular circumferential reinforcing member is employed, the structure of the circumferential reinforcing member is simplified, and the mounting of the circumferential reinforcing member to the pipe body can be easily performed. Further, when a spiral-shaped circumferential reinforcing member is used, the number of components is small and the configuration is simple, and the circumferential reinforcing member can be attached according to the shape and dimensions of the pipe body. In the case where the reinforcing member is embedded in a filler, the strength against internal pressure can be further increased, and by using, for example, lead for the filler, the function as a heat insulator can also be achieved.
