The metal hose is coverd 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. According to the device, the existing metal hose structure is optimized. The reinforcement coil is designed in the metal hose, so that the intensity of the metal hose is improved, and a dual anti-explosion effect of the metal hose is achieved. The structure that the steel band is wound around the existing metal hose is optimized. Adjacent layers of all the layers of the steel band wound around the outer layer of the corrugated pipe are in contact in a dislocation manner due to changes of a coiling order, thereby suppressing generation of friction static electricity. | 05-05-2022 |
