The invention discloses a method for repairing a fire-fighting pipeline system on a vertical storage tank. The method comprises the following steps that a fire-fighting water supply pipeline on the steel vertical storage tank is disassembled, wherein the fire-fighting water supply pipeline comprises a fire-fighting water supply vertical pipe and a fire-fighting water supply ring pipe, a pipeline support used for allowing the fire-fighting water supply pipeline to be installed and fixed on the steel vertical storage tank is inspected, the inner end of the pipeline support is fixed on the outerside wall of the steel vertical storage tank in a welding mode, and a liquid-state flammable and explosive substance is stored in the steel vertical storage tank. According to the method for repairingthe fire-fighting pipeline system on the vertical storage tank, hot welding work does not need to be performed on the steel vertical storage tank, so that the fire hazard and the explosion risk possibly caused by the hot work
