Piping for redox flow battery, manufacturing method of piping for redox flow battery, and piping unit, redox flow battery

摘要

An object of the present invention is to provide a pipe for a redox flow battery installed between a tank storing an electrolyte solution and a battery element and through which the electrolyte solution flows, and connecting a plurality of parallel parts arranged in parallel and the adjacent parallel parts to each other When it has a plurality of bending portions, and includes a meandering portion in which the parallel portion and the curved portion are integrally formed in succession alternately, the outer diameter is D, and the distance between the centers of the adjacent parallel portions is X , to provide a redox flow battery piping that satisfies the ratio of the center-to-center distance X and the outer diameter D is not less than 1.2 and not more than 2.5.
