What Are The Characteristics And Uses Of Hose Assemblies?

Hose assemblies are commonly used auxiliary equipment in hydraulic systems. Using high-pressure steel wire braided or spiral-wound hoses and steel fittings crimped by special equipment, they are used to connect various hydraulic components. They are primarily used to transmit hydraulic power or high-pressure media such as water, gas, and oil at working temperatures ranging from -40℃ to 100℃, ensuring liquid circulation and the delivery of fluid energy.

What are the characteristics and applications of hose assemblies?

High-pressure hose assemblies generally consist of a fluid-resistant synthetic rubber inner tube, an intermediate rubber layer, I to IV layers of steel wire braided reinforcement, and a synthetic rubber outer cover with excellent weather resistance. They are mainly used to transmit petroleum-based fluids (such as mineral oil, drilling mud, and hydraulic oil) at specific pressures and temperatures in mining hydraulic supports, oilfield extraction, construction engineering, lifting and transport, metallurgical forging, mining equipment, marine vessels, injection molding machines, agricultural machinery, various machine tools, and mechanized and automatic hydraulic systems across various industrial sectors.

How are hose assemblies designated?

What is the representation method for assembly length and assembly support?

When the hose assembly is laid out in a straight line, the angle between the other fitting and the vertical reference line is measured clockwise relative to the vertical direction of the distant fitting. This angle serves as the elbow angle.

What is the significance of hose assemblies?

A hose assembly refers to a complete technical and supply solution providing full connectivity for specified working conditions. It includes the hose (or rigid pipe), seals, and connecting fittings (such as couplings, flanges, etc.).

What are the classifications of high-pressure hose assemblies?

1. 1- and 2-wire braided hoses
   Suitable for high-pressure hydraulic systems using mineral oil-based hydraulic oils, alcohol-based hydraulic media, and water-oil emulsions.
   Temperature range: -40℃ to 100℃

2. 4-wire spiral hoses
   Applied in high-pressure hydraulic systems, high-pressure flow systems, and those using mineral oil-based hydraulic oils, alcohol-based hydraulic media, and water-oil emulsions.
   Temperature range: -40℃ to 100℃

3. 6-wire spiral ultra-high-pressure hoses
   Suitable for ultra-high-pressure hydraulic systems using mineral oil-based hydraulic oils, alcohol-based hydraulic media, and water-oil emulsions.
   Temperature range: -40℃ to 100℃
