The field of metal hoses, and specifically, an explosion-proof flexible metal hose for natural gas pipelines is concerned. The problems that the existing metal hose has low intensity and high flow velocity are solved. The explosion-proof flexible metal hose for natural gas pipelines includes a metal hose. A side of the metal hose is provided with a fixing assembly composed of a flange and a loose flange, and an other side of the metal hose is provided with a welding neck flange configured for fixing. The metal hose is covered with a steel band with a multilayer structure. The metal hose and two ends of the steel band are fixed through cooperation between metal short sections and pressing clamp rings. A reinforcement coil is wound around the metal hose.
