FAQ
What are the main application scenarios for hydraulic hoses?
Hydraulic arm connections for construction machinery: excavators, loaders, and cranes.
Industrial equipment: Hydraulic power transmission for injection molding machines, die casting machines, and machine tools.
Mining and Metallurgy: Hydraulic supports for mine shafts, high-pressure oil pipeline conveyance.
Agricultural machinery: hydraulic systems for tractors and harvesters.
Marine equipment: hydraulic control for steering gear and deck machinery.
What are the main structural components of a hydraulic hose?
Inner rubber layer: Directly contacts hydraulic oil and must possess oil resistance and corrosion resistance to protect the steel wire layer from erosion.
Middle rubber layer: Enhances the adhesion strength between the reinforcement layer and the inner rubber layer.
Steel wire reinforcement layer: Composed of steel wires woven or wrapped together, it provides pressure-bearing capacity. The greater the number of steel wire layers, the higher the pressure resistance.
Outer rubber layer: Protects the steel wire layer from mechanical damage, chemical corrosion, and UV aging.
In which scenarios is it appropriate to use hose crimp fittings?
High-pressure hydraulic systems: such as construction machinery, injection molding machines, hydraulic presses, and more.
Chemical medium conveyance: such as the transport of corrosive fluids in the food, pharmaceutical, and chemical industries.
Frequent disassembly and assembly scenarios: When quick hose replacement is required, a quick-change crimp fitting can be selected.
High-temperature/low-temperature environments: such as high-temperature or low-temperature connectors used in metallurgy and refrigeration equipment.
What is a hose crimp fitting?
A hose crimp fitting is a type of connection component that uses specialized equipment—such as a crimping machine—to integrally join the fitting’s outer sleeve with the hose and fitting core. It is widely used in hydraulic systems, industrial piping, and other applications. Its key features include reliable sealing and excellent resistance to delamination, making it suitable for high-pressure environments.
