Core Differences Between Wire-Braided And Wire-Spiral Hydraulic Hoses
Dec 23, 2025| Wire-braided hydraulic hoses and wire-spiral hydraulic hoses are the two most commonly used flexible pipelines in hydraulic systems. Their core differences lie in four dimensions: reinforcement layer structure, pressure rating, flexibility performance, and application scenarios. The detailed comparison is as follows:
| Comparison Dimension | Wire-Braided Hydraulic Hose | Wire-Spiral Hydraulic Hose |
|---|---|---|
| Reinforcement Layer Structure | The reinforcement layer is made of 1–2 layers of high-strength steel wire, adopting a cross-braiding process (braiding angle is generally 45°). The steel wires are interwoven in a mesh pattern along the hose axis and wrapped around the outer layer of the inner rubber. | The reinforcement layer is composed of 2 or more layers of high-strength steel wire, adopting a helical winding process (winding angle is generally 54°44′). Multiple layers of steel wires are spirally wound along the circumferential direction of the hose, with opposite directions between adjacent layers. |
| Pressure Rating | Medium working pressure: the working pressure of common 1-layer braided hoses ranges from 6–35MPa, and that of 2-layer braided hoses ranges from 21–63MPa; the burst pressure is usually 3–4 times the working pressure. | High working pressure: the working pressure of 2-layer spiral hoses can reach 40–100MPa, and that of 4-layer spiral hoses can be as high as 140MPa; the burst pressure is 4–5 times the working pressure, with stronger resistance to impact pressure. |
| Flexibility & Bending Performance | The braided structure offers better softness and a smaller minimum bending radius (usually 4–8 times the outer diameter of the hose), suitable for scenarios requiring frequent bending. | The spiral structure has higher rigidity and a larger minimum bending radius (usually 8–12 times the outer diameter of the hose), with poor bending flexibility, not suitable for small-radius bending working conditions. |
| Inner Diameter & Flow Rate | Relatively smaller inner diameter under the same outer diameter, limited flow rate, more suitable for small and medium flow hydraulic systems. | Larger inner diameter under the same outer diameter, low fluid resistance, large flow rate, suitable for high-flow and high-pressure hydraulic systems. |
| Applicable Pressure Scenarios | Low and medium pressure hydraulic systems, such as machine tool hydraulic systems, auxiliary oil circuits of small construction machinery, and low-pressure return oil circuits of hydraulic pump stations. | High and ultra-high pressure hydraulic systems, such as main oil circuits of large construction machinery (excavators, crane hydraulic arms), mining equipment, and high-pressure power oil circuits of metallurgical equipment. |
| Fatigue Resistance & Durability | Good bending fatigue resistance, suitable for working conditions with frequent reciprocating movement; however, its resistance to external pressure extrusion and burst is weaker than that of spiral hoses. | Strong resistance to burst and extrusion, good impact pressure resistance; but poor bending fatigue resistance, frequent bending may lead to fatigue fracture of steel wires in the reinforcement layer. |
| Cost & Craftsmanship | Simple braiding process, high production efficiency, low material cost, and more affordable overall price. | Complex winding process, high precision requirements for equipment in multi-layer winding, high material and processing costs, and higher price than braided hoses. |
| Typical Application Cases | Hydraulic lifting oil circuits of forklifts, hydraulic fixture oil circuits, auxiliary oil circuits of small loaders. | Main pump to main valve oil circuits of excavators, telescopic arm oil circuits of cranes, hydraulic support oil circuits of mines. |
Supplementary Selection Points
- If the working pressure of the hydraulic system is ≤ 63MPa, frequent bending is required, or the space layout is compact → wire-braided hydraulic hose is preferred.
- If the system working pressure is ＞ 63MPa, the flow rate is large, the working condition is stable, and small-radius bending is not required → wire-spiral hydraulic hose is preferred.
- The outer rubber material of both hoses should be matched according to the service environment: for example, neoprene outer rubber is selected for wear-resistant working conditions, and fluororubber outer rubber is selected for corrosion-resistant working conditions.
