EN856 4SH 2-Inch DN50 Hydraulic Hose: Special Pipeline for Heavy Equipment under 25MPa High Pressure
In heavy operation scenarios such as mining, engineering infrastructure and port operation and maintenance, the pipeline reliability of high-pressure hydraulic systems directly determines the operation safety of the whole set of equipment. With the powerful performance of 25MPa rated working pressure, the EN856 4SH 2-inch DN50 hydraulic hose has become the core supporting component of the hydraulic circuits of various high-horsepower heavy equipment, adapting to the extreme use environment with long-term high-frequency pulsation and high-load impact.
Four-Layer Steel Wire Spiral Structure Ensures 25MPa Pressure Stability
This hydraulic hose is designed in strict accordance with the EN856 4SH standard. It adopts an oil-resistant synthetic rubber inner tube, matched with a four-layer high-tensile alternately spiraled steel wire reinforcement structure, and is covered with an oil-resistant and weather-resistant synthetic rubber outer cover. Under the 2-inch DN50 diameter specification, it can stably maintain a continuous working pressure of 25MPa, and the minimum burst pressure can reach more than 100MPa, far exceeding the pressure-bearing level of conventional hydraulic hoses of the same specification, which can easily cope with the instantaneous pressure peak impact of the hydraulic system of heavy equipment. The minimum bending radius of the product is only 700mm, and the reference weight is about 4.55~5.0kg/m, which takes into account both high pressure-bearing capacity and installation flexibility, and adapts to complex on-site layout spaces.
Full-Scenario Adaptation for Hydraulic Systems of Multiple Types of Heavy Equipment
The performance characteristics of the EN856 4SH 2-inch DN50 hydraulic hose fully match the high-pressure use requirements of various heavy equipment:
In the mining field, it is adapted to hydraulic supports, which can withstand the continuous high pressure of complex underground working conditions and ensure the stable output of support actions
In the field of engineering equipment, it is adapted to large excavators, rotary drilling rigs and shield machines, resisting frequent pressure pulsations during operation and extending the pipeline replacement cycle
At the same time, it can be perfectly adapted to lifting equipment, land drilling equipment, metallurgical presses, port cranes and marine hydraulic systems, covering most high-pressure heavy-duty hydraulic application scenarios.
Long-Term Operation Advantages under Severe Working Conditions
Different from ordinary low-pressure hydraulic hoses, the EN856 4SH 2-inch DN50 hydraulic hose can stably convey conventional hydraulic media such as petroleum-based hydraulic oil and water-glycol based fluid in a wide temperature range from -40°C to +100°C. The outer cover has excellent wear resistance, oil resistance and aging resistance. Even in the harsh environments of mine gravel friction, construction site oil erosion and marine salt spray corrosion, it can still maintain long-term reliable operation, greatly reducing the pipeline maintenance cost and shutdown risk of heavy equipment.
