EN856 4SP hose is a kind of high-pressure hydraulic hose and is widely used in various industrial fields.
Inner rubber layer: Usually made of oil-resistant synthetic rubber, such as nitrile rubber (NBR), it has excellent oil resistance and can effectively resist the erosion of media such as petroleum-based hydraulic oil.
Reinforcing layer: Composed of four layers of high-strength spiral steel wires wound around it, the steel wires are copper-plated steel wires. This structure endows the hose with extremely high strength and pressure resistance.
The outer rubber layer is generally made of synthetic rubber that is wear-resistant, weather-resistant and ozone-resistant, such as chloroprene rubber (CR), which can protect the internal structure of the hose from the influence of the external environment and extend the service life of the hose.
Pressure resistance performance: The four-layer steel wire wound structure enables it to withstand extremely high pressure, with a burst pressure of ≥100MPa and a maximum working pressure of approximately 7250psi.
Temperature resistance range: The general working temperature range is -40 ℃ to + 100℃ (-40℉ to + 212℉), and some hoses can withstand a maximum temperature of 125℃ for a short period of time.
Weather resistance: The weather resistance of the outer rubber layer enables it to be used in various harsh outdoor environments, resisting damage to the hose caused by ultraviolet rays, ozone, etc.
Flexibility: Some EN856 4SP hoses have excellent flexibility and can still pass the 1 million pulse cycle test even when the bending radius is lower than the EN856 standard.
It is suitable for various media, including mineral oil, vegetable oil, water, diols, water/mineral oil emulsions, etc.
Mainly applied in high-pressure hydraulic systems, such as forklifts, hydraulic engines, oilfield extraction machinery, mining machinery, road construction machinery, construction machinery and other fields.
