Abstract
A redox flow battery pipe which is disposed between a tank that stores an electrolyte and a battery element and through which the electrolyte flows includes a plurality of parallel portions arranged in parallel and a plurality of bent portions connecting the parallel portions adjacent to each other. The pipe includes a meandering portion in which the parallel portions and the bent portions are integrally molded so as to be alternately connected. A ratio of a center-to-center distance X to an outer diameter D satisfies 1.2 or more and 2.5 or less where D represents an outer diameter and X represents a distance between centers of the parallel portions adjacent to each other.
