摘要：PROBLEM TO BE SOLVED: To provide a vertical pipe capable of making fluid flowing down the insides of pipe main bodies as a circling current by spiral guide channels flow out in a state to lower a flowout velocity from an outlet or in a state of steady flow. SOLUTION: A vertical pipe is so constituted that fluid flowing into straight pipe-like pipe main bodies 12a and 14a to be vertically arranged is led by spiral guide channels 12c and 14b provided to the pipe main bodies to flow down the insides of the pipe main bodies. Then, an outlet 14c of fluid flowing down the insides of the pipe main bodies is provided to the circumferential surfaces in the lower ends of the pipe main bodies located downward from the lower ends of the spiral guide channels, and the inside diameter of the outlet 14c is smaller than the inside diameters of the pipe main bodies 12a and 14a.
