High-pressure hoses are used for conveying fluids at specific pressures and temperatures in hydraulic systems for mine supports, oilfield development, construction, lifting and transportation, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanical and automated hydraulic systems in various industrial sectors. These fluids include petroleum-based ones (such as mineral oil, soluble oil, hydraulic oil, fuel oil, and lubricating oil) and water-based liquids (such as emulsions, oil-in-water emulsions, and water) for liquid conveyance.
