Hose assemblies are commonly used auxiliary components in hydraulic systems. Manufactured by crimping high-pressure steel wire braided or spiral hoses and steel fittings with specialized equipment, they connect various hydraulic components. They are primarily used to transmit hydraulic power or convey high-pressure media such as water, gas, and oil at operating temperatures ranging from -40°C to 100°C, supporting liquid circulation and energy transfer.
What are the features and applications of hose assemblies?
High-pressure hose assemblies generally consist of a liquid-resistant synthetic rubber inner tube, an intermediate rubber layer, I to VI layers of steel wire braided reinforcement, and a weather-resistant synthetic rubber outer cover. They are mainly used to transmit hydraulic fluids at specific pressures and temperatures in mechanized and automated hydraulic systems across various industrial sectors, including mining hydraulic supports, oilfield extraction, construction engineering, lifting and transportation, metallurgy and forging, mining equipment, marine vessels, injection molding machinery, agricultural machinery, and various machine tools. The applicable media include petroleum-based hydraulic oils (e.g., mineral oils, hydraulic oils, lubricating oils), water-based liquids, and emulsions.
How are hose assemblies specified?
How are assembly length and assembly support indicated?
When the hose assembly is laid out in a straight line, the angle is measured clockwise from the vertical plane of one fitting to the vertical plane of the other fitting. This angle serves as the orientation angle.
What is the definition of a hose assembly?
A hose assembly refers to a complete technical and supply solution providing integrated connectors for specified working conditions. It includes the hose (or rigid tube), seals, and connection fittings (such as couplings and flanges).
What are the classifications of high-pressure hose assemblies?
1- and 2-Wire Braided Hoses
Suitable for high-pressure hydraulic systems using mineral oil-based hydraulic fluids, glycol-based hydraulic media, and water-oil emulsions.
Temperature range: -40°C to 100°C.
4-Wire Spiral Hoses
Applied in high-pressure hydraulic systems and high-flow systems using mineral oil-based hydraulic fluids, glycol-based hydraulic media, and water-oil emulsions.
Temperature range: -40°C to 100°C.
6-Wire Spiral Ultra-High-Pressure Hoses
Suitable for ultra-high-pressure hydraulic systems using mineral oil-based hydraulic fluids, glycol-based hydraulic media, and water-oil emulsions.
Temperature range: -40°C to 100°C.
