Steel wire spiral hose is mainly used in hydraulic support of mines and oil field development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and mechanized and automated hydraulic systems in various industrial sectors. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water) and liquid transmission with a certain pressure (higher pressure) and temperature, **High working pressure can reach 70-120Mpa.
　　 1. Structure: composed of inner rubber layer, inner rubber protective layer, middle rubber layer, steel wire winding layer and outer rubber layer.
　　 2. Uses: Wire-wound drilling hoses are used for fluid medium such as oilfield cementing, workover and petroleum geological exploration, small drilling rigs and hydraulic coal mining, transportation of mud and normal temperature water.
