Introduction of EN856-4SP Wire spiral hydraulic rubber hose

EN856-4SP is a specification for high-pressure steel wire reinforced rubber hoses. It is a standard established by the European Committee for Standardization (CEN) and is widely used in hydraulic systems.

The “EN856” in the specification refers to the European standard for hydraulic hoses, specifically EN 856: Rubber hoses and hose assemblies - Rubber-covered spiral wire reinforced hydraulic type. The “4SP” indicates the hose’s reinforcement type, in this case, four spiral layers of high-tensile steel wire.

Steel wire wound rubber hoses are designed to withstand high pressures and provide flexibility in hydraulic applications. These hoses are commonly used in heavy machinery, construction equipment, mining, and industrial sectors.

The inner tube of the hose is made of synthetic rubber, which is capable of handling various hydraulic fluids like mineral oils, lubricants, water-emulsion, and water-glycol mixtures. The reinforcement of high-tensile steel wires provides excellent strength and resistance against pressure and abrasion.

EN856-4SP hoses typically have a black outer cover made of synthetic rubber that protects the inner layers and provides additional resistance to weather, ozone, and aging. They have excellent impulse resistance, which means they can handle rapid pressure fluctuations and pulsations without failure.

Overall, EN856-4SP steel wire wound rubber hoses are recognized for their high-pressure capabilities, durability, and flexibility, making them suitable for demanding hydraulic applications.
