High-Pressure Steel Wire Spiral Hydraulic Hoses – Product Details

1. Product Structure Type

The hose is mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, 2/4/6 layers of steel wire spiral reinforcement, and an outer rubber layer.

• The inner rubber layer enables the conveyed medium to withstand pressure and protects the steel wires from corrosion.
• The outer rubber layer protects the steel wires from mechanical damage.
• The steel wire reinforcement (made of φ0.3–2.0mm high-tensile steel wires) acts as the reinforcing skeleton material to provide structural strength.

2. Application

High-pressure steel wire reinforced hydraulic hoses are mainly used for mine hydraulic supports and oilfield exploitation. They are suitable for conveying petroleum-based fluids (e.g., mineral oils, soluble oils, hydraulic oils, fuels, lubricating oils) and water-based fluids (e.g., emulsions, oil-water emulsions, water) under specified (high) pressure and temperature, as well as for fluid power transmission in mechanized and automated hydraulic systems across engineering construction, hoisting & transportation, metallurgical forging, mining equipment, marine vessels, injection molding machinery, agricultural machinery, various machine tools, and other industrial sectors. The maximum working pressure resistance reaches 70–100 MPa.

Note: Our steel wire spiral hoses are manufactured in accordance with GB/T 10544-2003, DIN 20023, and SAE 100R9~13 standards. These standards are not applicable to castor oil-based or grease-based fluids.
