Composed of an inner rubber layer + middle rubber layer + multiple layers (4/6 layers) of steel wire winding reinforcement + outer rubber layer. The Rubber High-Pressure Oil Hose are spirally stacked, providing extremely high pressure resistance (working pressure can reach 70-120MPa, ultra-high pressure models can even be higher).

Excellent anti-pulse performance, able to withstand frequent pressure shocks, suitable for high-pressure hydraulic systems.

Temperature Resistance and Media Compatibility

Operating temperature range: -40℃~120℃, adaptable to extreme environments.

Compatible with petroleum-based liquids (mineral oil, hydraulic oil, fuel oil), water-based liquids (emulsions, water), etc. Some models are resistant to corrosive fluids. Physical Properties

The tube body is flexible but deforms little under pressure, resistant to bending and fatigue. The outer rubber layer is wear-resistant, anti-aging, and resistant to environmental corrosion (such as dust and moisture).

Main Application Scenarios: Heavy industry and engineering machinery, excavators, cranes, loaders, etc., hydraulic systems, undertaking high-pressure power transmission. Mining and Energy Sector

Coal mine hydraulic supports, oilfield drilling/cementing/workover (transporting drilling mud and oil), and shallow-sea oil pipelines for offshore oil extraction. Other Industrial Scenarios

High-pressure hydraulic systems in metallurgical forging equipment, marine hydraulic systems, injection molding machinery, and agricultural machinery.

Characteristics of Different Types of Spiral Wound Pipes

Number of Layers: 2SP (2 layers of steel wire winding), 4SP (4 layers), 6SP (6 layers). More layers mean stronger pressure resistance.

Pressure Relationship: The minimum burst pressure is typically 4 times the working pressure (slight differences may occur for some models due to standard variations), ensuring safety redundancy.

Bending Radius: The larger the inner diameter and the more layers, the larger the bending radius. Selection should be based on installation space.

High pressure hydraulic hoses are critical components in modern fluid power systems. They are designed to safely transmit hydraulic fluid under extremely high pressures, enabling heavy machinery, industrial equipment, and mobile systems to operate efficiently and reliably.
