High pressure hose is mainly composed of an inner layer, the middle layer, the liquid resistance of 2 or 4 or 6 layers of spiral steel wire reinforced layer and the outer layer, inner layer has to withstand the pressure transmission medium, wire protection from erosion effect, outer layer protection wire is not damaged, the steel skeleton material layer is enhanced. The product is mainly used for mine hydraulic support, oil exploitation, suitable for engineering construction, lifting transport, metallurgy, shipbuilding, mining equipment forging, injection molding machinery, agricultural machinery, machine tools and various industrial sectors of mechanization and automation of hydraulic system in transportation with certain pressure (high pressure) and temperature (such as petroleum, mineral oil soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, water emulsion, water etc.) and liquid transmission, high working pressure up to 60MPa
