PIPE CONNECTION STRUCTURE AND MANUFACTURING METHOD OF PIPE CONNECTION STRUCTURE

To provide a pipe connection structure capable of enhancing chemical resistance.SOLUTION: A pipe connection structure comprises a multilayer pipe, a member to be connected, and an adhesive layer. The multilayer pipe has a tubular inner layer, and an outer layer arranged on an external surface of the inner layer. The adhesive layer is arranged between an outer peripheral surface of the multilayer pipe and a surface of the member to be connected. The adhesive layer reaches an end surface of the multilayer pipe from the outer peripheral surface of the multilayer pipe, and at least a part of the end surface of the multilayer pipe is covered with the adhesive layer.SELECTED DRAWING: Figure 1 【課題】耐薬品性を高めることができる管接続構造体を提供する。【解決手段】本発明に係る管接続構造体は、多層管と、接続対象部材と、接着剤層とを備え、前記多層管は、管状の内層と、前記内層の外表面上に配置された外層とを有し、前記接着剤層は、前記多層管の外周面と前記接続対象部材の表面との間に配置されており、前記接着剤層は、前記多層管の外周面上から前記多層管の端面上に至っており、前記多層管の端面の少なくとも一部が、前記接着剤層により覆われている。【選択図】図１
