PIPE DEVICE AND CORRUGATED DOUBLE PIPE
To provide a pipe device and a corrugated double pipe capable of suppressing axial movement while having function performance.SOLUTION: A corrugated double pipe 50 constituting a pipe device 10 has a two-layer structure consisting of a cylindrical inner layer 51 made of a non-foamed synthetic resin material and a cylindrical outer layer 52 made of a foamed synthetic resin material that is in close contact with the outer peripheral surface of the inner layer 51 in the entire axial direction. The corrugated double pipe 50 has annular recesses 53 and annular protrusions 54 that are alternately provided along the axial direction. A faucet box constituting the pipe device 10 has a pipe connecting part 20 into which the axial end part of the corrugated double pipe 50 is inserted, and a locking projection 23 that enters the recess 53 of the corrugated double pipe 50. When the corrugated double pipe 50 is pulled in the extraction direction with respect to the faucet box with the locking projection 23 locked to the protrusion 54, the outer layer 52 has a hardness that does not release the locking projection 23.SELECTED DRAWING: Figure 5
【課題】機能性能を有しつつ軸方向への移動を抑制できる管装置及び波付二重管を提供すること。【解決手段】管装置１０を構成する波付二重管５０は、非発泡の合成樹脂材料からなる筒状の内層５１と、内層５１の外周面に密着し、発泡させた合成樹脂材料からなる筒状の外層５２との二層構造を軸方向全体に有する。波付二重管５０は、軸方向に沿って交互に設けられた環状の凹部５３と環状の凸部５４とを有する。管装置１０を構成する水栓ボックスは、波付二重管５０の軸方向端部が内挿される管接続部２０、及び波付二重管５０の凹部５３に入り込む係止突起２３を有する。係止突起２３を凸部５４に係止させた状態で、波付二重管５０を水栓ボックスに対する抜け出し方向に引っ張ったときに、外層５２は係止突起２３の係止が解除されない硬さを有する。【選択図】図５
