High Temperature Resistance En856-4sh Spiral Wire Hydraulic Hose

Product Description

High Temperature Resistance EN856-4SH Spiral Wire Hydraulic HoseProduct Description
Performance characteristics
* High working pressure, with a high working pressure range, the maximum working pressure can usually reach more than 45MPa, the specific pressure value depends on the size of the hose, and can meet the needs of most high-pressure hydraulic systems.
* Excellent pulse performance, up to 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 temperature and working temperature conditions, and can adapt to cold and high temperature working environments.
* Good flexibility, despite the four layers of steel wire winding reinforcement, it still maintains good flexibility, is easy to bend and install, can adapt to complex hydraulic system layout, and is convenient for pipeline laying in a small space.The special rubber formula used in the inner rubber layer has certain self-healing properties. When tiny cracks appear inside the hose due to pressure shock, the special chemical bonds in the rubber molecules will reorganize and repair themselves to a certain extent, delaying the expansion of the cracks and reducing the risk of leakage or failure due to minor damage.

Good Dimensional Stability
Under high pressure, the diameter and length of wire-wound hydraulic hoses vary less than other types of hoses. This is because the wire-wound layer has a good restraining effect on the shape of the hose.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.Adapt To a Variety Of Hydraulic Media
Due to the good performance of the inner rubber layer material, wire-wound hydraulic hoses are compatible with a variety of hydraulic media of different properties, including water-based hydraulic oil, petroleum-based hydraulic oil, emulsion, etc.High Safety Factor
With advantages such as pressure resistance, fatigue resistance, and wear resistance, wire-wound hydraulic hoses have a high safety factor. Even in some extreme working conditions, such as sudden pressure shocks or local physical damage, it has a certain ability to maintain integrity and avoid serious accidents such as hydraulic oil leakage.Sealing performance
It has excellent sealing performance, the inner rubber layer is in good contact with the hydraulic medium, and the outer rubber layer and joints and other connecting parts can effectively prevent hydraulic oil leakage. This is crucial to ensure the efficient operation of the hydraulic system and avoid environmental pollution.Company Profile
