Hydraulic hoses, also known as hydraulic oil pipes, hydraulic hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure pipes, steel wire braided hoses, and steel wire wrapped hoses, are generally divided into steel wire braided hydraulic hoses and steel wire wrapped hydraulic hoses. Hydraulic hoses are mainly composed of liquid resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer, and outer rubber layer. The inner rubber layer has the function of bearing pressure on the conveying medium and protecting the steel wire from erosion, while the outer rubber layer protects the steel wire from damage. The steel wire layer is the skeleton material that plays a reinforcing role.
The standards commonly used in domestic and foreign trade for hydraulic hoses include DIN, SAE, ISO, and GB/T standards;
The standards for steel wire braided hydraulic hoses are: DIN EN 853, SAE J517, GB/T 3683-2011, ISO1436;
The standards for wire wound hydraulic hoses are DIN EN 856, SAE J517, GB/T 10544-2003, and ISO3862.
The product is mainly used for hydraulic supports in mines and oil field extraction, 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 to transport petroleum based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) with certain pressure (high pressure) and temperature, as well as liquid transmission
