    • PROBLEM TO BE SOLVED: To provide a piping device capable of preventing transmission of noise and reducing its mounting space. SOLUTION: The piping device having a dual pipe structure carries out heat exchange between high-pressure coolant flowing through an outside flow passage 230 formed outside an inner pipe 220 inside an outer pipe 210 and low-pressure coolant flowing through an inside flow passage 240 formed inside the inner pipe 220. The piping device includes a spiral groove part 222 spirally formed on a pipe wall of the inner pipe 220, a spiral ridge part 223 partitioning the spiral groove part 222, a flow separating pipe 250 provided for a part of and inside the inner pipe 220 in the axial direction, supported by the spiral groove part 222, and forming a flow-separating area 255 for partially separating the inside flow passage 240, a main flow passage 251 formed inside the flow separating pipe 250 for circulating the low-pressure coolant, and a bypass flow passage 252 formed inside the ridge part 223 on the outside of the flow separating pipe 250 for circulating the low-pressure coolant in a path length different from that of the main flow passage 251.
