YITAI EN856-4SH Wire spiral hydraulic rubber hose Parameter (Specification)

Introduction of EN856-4SH Wire spiral hydraulic rubber hose
EN856-4SH is a specification for high-pressure steel wire spiral reinforced rubber hoses. Similar to EN856-4SP, 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 “4SH” indicates the hose’s reinforcement type, in this case, four spiral layers of high-tensile steel wire.

EN856-4SH steel wire spiral rubber hoses are designed to handle even higher working pressures compared to EN856-4SP hoses. The spiral wire reinforcement provides excellent strength and resistance against pressure and bending. These hoses are commonly used in applications where extremely high pressures are encountered, such as in heavy machinery, mining, construction, and oil industries.

The inner tube of the hose is made of synthetic rubber, which is compatible with various hydraulic fluids such as mineral oils, lubricants, water-emulsion, and water-glycol mixtures. The steel wire spiral reinforcement enhances the hose’s resistance to high-pressure conditions and offers excellent flexibility.

EN856-4SH hoses typically have a black outer cover made of synthetic rubber that provides additional protection against abrasion, weather, ozone, and aging. They have excellent impulse resistance, allowing them to withstand rapid pressure fluctuations and pulsations without failure.

Overall, EN856-4SH steel wire spiral rubber hoses are known for their high-pressure capabilities, durability, flexibility, and resistance to extreme conditions, making them suitable for heavy-duty hydraulic applications.

YITAI EN856-4SH Steel wire spiral rubber hose Feature And Application
EN856-4SH steel wire spiral rubber hoses are commonly used in various hydraulic applications that require high-pressure capabilities and resistance to extreme conditions. Some of the applications include:
Heavy machinery: These hoses are used in construction equipment, earthmoving machinery, and other heavy machinery that require hydraulic systems to operate various functions. The high-pressure resistance and durability of EN856-4SH hoses make them suitable for handling the hydraulic fluids and pressures involved in these applications.

Mining industry: In the mining industry, hydraulic systems are extensively used for drilling, excavation, and transportation of materials. EN856-4SH hoses are suitable for such applications due to their ability to withstand high-pressure conditions, rugged environment, and abrasive materials typically found in mining operations.

Oil and gas industry: The oil and gas industry involves high-pressure hydraulic systems for drilling, well control, and fluid transfer. EN856-4SH hoses can handle the demanding requirements of these applications, including the high-pressure hydraulic fluids and harsh environments encountered in oil and gas exploration, production, and refining.

Construction industry: EN856-4SH hoses find applications in construction machinery, such as cranes, excavators, loaders, and other hydraulic equipment. These hoses can withstand the high pressures and dynamic loads associated with heavy construction activities while providing flexibility and reliability.

Industrial sectors: Various industrial applications require hydraulic systems to power machinery, presses, material handling equipment, and other processes. EN856-4SH hoses are suitable for such applications that involve high-pressure fluids and demanding conditions.

In summary, EN856-4SH steel wire spiral rubber hoses are extensively used in industries such as heavy machinery, mining, oil and gas, construction, and other industrial sectors where high-pressure hydraulic systems are required. These hoses provide the necessary strength, flexibility, and durability to handle demanding hydraulic applications in extreme conditions.
