The high-pressure hose assembly is generally composed of a liquid-resistant synthetic rubber inner rubber layer, a middle rubber layer, Ⅰ to Ⅵ steel wire braided reinforcing layers, and a weather-resistant synthetic rubber outer rubber layer. Mainly used in hydraulic support of mines and oilfields, suitable for engineering and construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and various industrial sectors. And temperature of petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) liquid, water-based liquid (such as emulsion, oil-water emulsion, water), gas, and liquid transmission and other fields.
