Provided is a piping device that improves the irradiation effect of fluid. A piping device includes a main body, a flow channel module, and a plurality of light emitting elements. The main body is provided with a storage chamber and a plurality of light transmission holes. The storage chamber is provided inside the main body. The plurality of light transmission holes penetrate the main body 10 at intervals and communicate with the housing chamber and the outside of the main body 10, and the flow path module 20 is coupled to the main body 10, and the transparent tube 21 and the guide member 22. The transparent tube 21 is provided inside the accommodating chamber, and the guide member 22 has a spiral structure, and is provided inside the transparent tube 21, so that the flow path module 20 has a spiral shape. The flow path 23 is formed, and the plurality of light emitting elements 31 are connected to the main body 10 and provided at intervals from each other, enter the plurality of light transmission holes, and are positioned around the flow path module 20. [Selection] Figure 3【課題】流体の照射効果を改善する配管装置を提供する。【解決手段】配管装置であって、本体１０、流路モジュール２０及び複数の発光素子３１を備え、本体１０に収容チャンバと複数の光透過孔が設けられ、収容チャンバは本体１０の内部に設けられ、複数の光透過孔は間隔をおいて本体１０を貫通して収容チャンバ及び本体１０の外部と連通し、流路モジュール２０は、本体１０と結合され、且つ透明な管材２１及びガイド部材２２を備え、透明な管材２１は収容チャンバの内部に設けられ、ガイド部材２２は、螺旋状の構造を有し、且つ透明な管材２１の内部に設けられることにより、流路モジュール２０に螺旋状の流路２３が形成され、複数の発光素子３１は、本体１０に接続され、且つ互いに間隔をおいて設けられ、複数の光透過孔に入り、且つ流路モジュール２０の周囲に位置する。【選択図】図３
