SAE R12 hose is a high-performance hydraulic hose manufactured in accordance with the standards of the Society of Automotive Engineers (SAE) of the United States. It is specifically designed to meet the high-pressure hydraulic applications under harsh working conditions and plays a crucial role in the hydraulic systems of many industries.
Inner tube: The inner tube is made of oil-resistant synthetic rubber and has excellent resistance to common hydraulic oil, lubricating oil, fuel oil (such as gasoline, diesel, etc.) and crude oil. Its molecular structure is compact, which can effectively prevent the penetration of the medium, avoid the swelling, embrittlement or chemical corrosion of the inner tube due to long-term contact with various media, ensure the purity and integrity of the medium during the transportation process, and lay a solid foundation for the stable operation of the entire hose system.
Reinforcing layer: This is the core guarantee for the pressure resistance performance of SAE R12 hoses. The reinforcing layer is constructed by spirally winding four high-strength steel wires, and the winding directions of the steel wires in adjacent layers alternate with each other.
Outer coating: The outer coating is made of synthetic rubber that is wear-resistant, ozone-resistant and highly weather-resistant.
High-pressure resistance capability: SAE R12 hoses have outstanding high-pressure resistance performance, with working pressures reaching a relatively high level, generally meeting the requirements of most high-pressure hydraulic systems.
Pulse resistance performance: During the operation of a hydraulic system, the pulse pressure generated by the flow of the medium is one of the key factors affecting the service life of the hose. The SAE R12 hose, with its four-layer steel wire helically wound reinforcing layer structure, can efficiently buffer the impact of pulse pressure.
Good flexibility: Despite being equipped with a strong steel wire reinforcement layer, the SAE R12 hose still maintains good flexibility. The appropriate bending radius enables it to be flexibly arranged in complex and compact equipment Spaces, easily bypassing various obstacles and achieving precise pipeline connections. In application scenarios with strict requirements for pipeline layout, such as precision mechanical equipment and aerospace equipment, its excellent flexibility advantage is fully demonstrated, ensuring the normal operation of the system while reducing potential damage to the pipe body caused by excessive bending.
In the construction machinery industry: SAE R12 hoses are widely used in hydraulic systems in construction machinery such as excavators, loaders, cranes and forklifts
In the field of industrial manufacturing, the hydraulic systems of industrial equipment such as injection molding machines, hydraulic presses, and metallurgical equipment also cannot do without SAE R12 hoses.
In the field of transportation: In shipbuilding, the hydraulic steering gear system is related to the safety of ship steering. SAE R12 hoses are used to transport high-pressure hydraulic oil to drive the steering gear and achieve ship steering operations.
