Wire braided hose and wire spiral hose are two common high-pressure hoses used in hydraulic systems, and are widely used in industries, construction, agriculture, and oil drilling. Although they are similar in appearance, they have significant differences in structure, performance, and use. In this article, Liwang Fluid Technology Department will compare the characteristics of these two hoses in detail to help users make the right choice based on actual needs.

 

1. Structural Differences

 

1.1 Wire Braided Hose

 

• Reinforcement Layer Structure: It consists of one or more layers of wire braided layers, and the wires are arranged in a cross-braided manner.
• Number of Layers: Usually 1-2 layers of braided layers, suitable for medium-pressure systems.
• Flexibility: Due to the braided structure, the wire braided hose has good flexibility and is suitable for occasions that require frequent bending.
• Outer layer and inner layer: The inner layer is oil-resistant and corrosion-resistant synthetic rubber, and the outer layer is wear-resistant and weather-resistant synthetic rubber.

 

1.2 Wire Wrap Hose

 

• Reinforcement layer structure: It is composed of multiple layers of wire wrapping, and the wires are arranged in a spiral winding manner.
• Number of layers: Usually 4-6 layers of wrapping layers, suitable for high-pressure systems.
• Rigidity: Due to the wrapping structure, the wire wrap hose has strong rigidity and poor flexibility, which is suitable for fixed installation.
• Outer layer and inner layer: The inner layer is a high-performance synthetic rubber or polymer material, and the outer layer is a wear-resistant and impact-resistant synthetic rubber.

 

2. Performance comparison

 

The following is a performance comparison table of wire braided hose and wire spiral hose:

 

Performance index	Wire braided hose	Wire spiral hose
Pressure resistance	Medium pressure system (10-35 MPa)	High pressure system (above 35 MPa, up to 100 MPa)
Flexibility	Suitable for frequent bending or movement	Poor, suitable for fixed installation or low-frequency dynamic application
Bending radius	Suitable for space-constrained environment	Large, requires larger installation space
Fatigue resistance	Suitable for dynami appliccation	Excellent, suitable for static or low-frequency dynamic application

 

3. Selection suggestions and typical applications

 

3.1 Selection and application of wire braided hose

 

Wire braided hose is suitable for medium pressure systems (10-35 MPa), and is commonly used in industrial hydraulic systems such as machine tools and injection molding machines, as well as hydraulic connections of agricultural machinery such as tractors and harvesters. It has good flexibility and is suitable for occasions that require frequent bending or movement, such as hydraulic systems of construction machinery such as excavators and bulldozers. In addition, due to its small bending radius, wire braided hose is also suitable for environments with limited installation space, and is often used in mobile equipment or compact machinery.

 

3.2 Selection and application of wire winding hose

 

Wire winding hose is suitable for high pressure systems (above 35 MPa), and is widely used in high pressure hydraulic systems such as oil drilling and mining machinery, as well as fixed equipment such as factory production lines and ship hydraulic systems. It has strong rigidity and is suitable for occasions with low flexibility requirements, such as large industrial equipment or fixed hydraulic systems. In addition, wire winding hose performs well under extreme working conditions and is suitable for high temperature, high pressure or corrosive environments, such as chemical equipment or deep sea drilling equipment.

 

In summary, there are significant differences in structure, performance and use between wire braided hose and wire spiral hose. Wire braided hose is suitable for medium pressure system and dynamic application due to its good flexibility and small bending radius, while wire spiral hose is suitable for high pressure system and fixed installation due to its excellent pressure resistance and fatigue resistance. By understanding the characteristics of these two hoses, Liwang Fluid recommends that users make reasonable selection according to actual needs to ensure efficient operation and long-term stability of the hydraulic system.
