Product Description

EN856 4SP Max 45 Mpa Steel Wire Spiral Hydraulic Oil Rubber Hose

Product Description

EN856 4SP Steel Spiral Hydraulic Hose Structural

Inner rubber layer: Made of black oil-resistant synthetic rubber, it is in direct contact with hydraulic oil and can effectively withstand all kinds of hydraulic oil.
Reinforcement layer: Made of four layers of high-strength steel wire spirally wound, the steel wire is wound in alternating directions, which can withstand extremely high pressure and pulse loads, and provide good pressure resistance and pulse resistance.
Outer rubber layer: It is an oil-resistant and weather-resistant synthetic rubber that can protect the hose from external environmental factors such as wear, chemical corrosion, ultraviolet radiation, and bad weather.
Excellent bending resistance and fatigue resistance can maintain good performance under frequent bending and torsion conditions, not easy to damage, the pipe body is tightly combined, and the deformation is small under pressure.

It is mainly used for mine hydraulic supports and oil field development. It is also suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors to transport petroleum-based and water-based liquids.

Performance Characteristics

High working pressure: It has a high working pressure range, and the maximum working pressure can usually reach more than 45MPa. The specific pressure value depends on the size of the hose, which can meet the needs of most high-pressure hydraulic systems.

Excellent Pulse Performance

It can reach more than 400,000 pulse cycles, can withstand frequent pressure changes and pulse shocks, and is not prone to fatigue damage and leakage.

Good Temperature Adaptability

The working temperature range is generally -40°C to +100°C. It can operate stably under different ambient and working temperature conditions and can adapt to cold and high temperature working environments.

Good Flexibility

Despite the four layers of wire winding reinforcement, it still maintains good flexibility, is easy to bend and install, can adapt to complex hydraulic system layouts, and is convenient for pipe laying in a small space.

Strong Wear Resistance

The outer rubber layer material is wear-resistant, and the internal wire-wound layer enhances the overall wear resistance. When the hose contacts or rubs against surrounding objects, it can effectively reduce wear. Wire-wound hydraulic hoses can work for a long time in this harsh friction environment, reducing the risk of failure caused by wear.
