Domestic Wire Spiral Hydraulic Hose Accelerates To Replace Imports, A New Engine For High-Pressure Equipment
In recent years, with the continuous upgrading of China's manufacturing, China Wire Spiral Hydraulic Hose has gradually emerged and become a reliable and economical choice in high-pressure hydraulic systems. Widely used in engineering machinery, mining equipment, agricultural machinery and other fields, Chinese hydraulic hose products are accelerating the pace of replacing imported brands.
What is a wire spiral hydraulic hose?
The wire spiral hydraulic hose is made of synthetic rubber as the inner layer and wear-resistant rubber as the outer layer, with multiple layers of high-strength steel wire spiral winding layers in the middle. This structure gives the hose extremely high pressure resistance and burst resistance, and can withstand continuous high-pressure shock and high-frequency vibration.
Typical working pressure can reach 25MPa to 45MPa, or even higher, and is widely used in the following scenarios:
Construction engineering: excavators, loaders, concrete pump trucks
Mining: drilling rigs, transport vehicles, hydraulic supports
Agricultural machinery: combine harvesters, tractor hydraulic systems
Industrial equipment: hydraulic molding machines, press-fitting equipment
Common Problem Analysis
Although the quality of domestic hydraulic hoses continues to improve, the following common problems should still be noted during actual use:
1. Pipe burst or leakage
Due to incorrect selection or exceeding the design pressure, some low-end products fail to pass strict testing.
2. Bending radius is too small
Irregular installation causes fatigue fracture of the steel wire layer and shortens the service life.
3. Aging and cracking of the outer layer
Long-term exposure to strong sunlight, oil pollution or high temperature environment will gradually lose the elasticity of the rubber sheath.
4. Improper joint installation
Failure to crimp according to specifications or use of mismatched joints will cause the joint to loosen or leak oil.
5. Inferior raw material problem
Some small factories use non-standard steel wire or recycled rubber. Although they can be used in the short term, their pressure resistance and life are worrying.
Use case: A certain infrastructure project in Sichuan
In a large mountain highway construction project in Sichuan, the construction party selected a domestic brand of 4-layer steel wire winding hydraulic hose, which was installed on excavators and concrete pump trucks. After 6 consecutive months of high-intensity operation, the hose did not burst or leak, and its performance was excellent. The maintenance cost was greatly reduced, which won high praise from the construction party.
Summary and trend
With the increase in investment by domestic manufacturing companies, more and more China-made hydraulic hoses have made breakthroughs in raw materials, winding processes, and crimping technologies. High cost-effectiveness, fast delivery, and customizability have become the significant advantages of Chinese hose products.
