Steel wire braided high-pressure resin hoses have demonstrated significant advantages and wide applications in transporting petroleum-based hydraulic fluids. The following is a detailed introduction to this hose and its applications:

1. Hose structure
Steel wire braided high-pressure resin hose is usually composed of a multi-layer structure, including an inner rubber layer, a reinforcement layer and an outer rubber layer.

Inner rubber layer: usually made of synthetic rubber with excellent oil resistance, such as nitrile rubber (NBR) or fluorine rubber (FKM), which provides the hose with good heat resistance and chemical stability, ensuring that it can transport petroleum bases. Hydraulic oil will not be damaged by chemical corrosion.
Reinforcement layer: Braided with high-strength steel wire, this layer greatly improves the working pressure and wear resistance of the hose, allowing it to withstand pressures up to hundreds of pascals and be used for a long time under high pressure, high temperature and harsh environments. without deforming or breaking.
Outer rubber layer: Generally made of polyurethane and other materials, it has excellent wear resistance and anti-aging properties, further protecting the hose from damage from the external environment.
2. Hose characteristics
High-pressure carrying capacity: The steel wire braided design ensures the high-pressure carrying capacity of the hose and can adapt to the requirements of high-power equipment without problems such as pipe expansion and rupture.
Wear resistance and corrosion resistance: High-pressure resin hoses have excellent oil resistance and chemical resistance, and can effectively resist the corrosion of hydraulic oil and other chemicals and extend their service life.
Flexibility: Despite its high strength, high-pressure resin hose still maintains excellent flexibility, which means it can be easily used in complex pipeline layouts without being too hard to cause installation difficulties. In addition, this flexibility also makes the hose more elastic and shock-resistant during operation, effectively improving the stability of the system.
High temperature resistance: In high-temperature operating environments, ordinary hoses may lose elasticity or even burst due to thermal expansion. The material properties of steel wire braided high-pressure resin hose give it excellent high-temperature resistance, making it suitable for use in harsh high-temperature environments without deformation or performance degradation due to temperature effects.
3. Application fields
Steel wire braided high-pressure resin hose is widely used in many fields due to its excellent performance, especially in situations where petroleum-based hydraulic oil needs to be transported. These areas include but are not limited to:

Construction machinery: Construction machinery needs to frequently change construction positions and operating conditions during the construction process, which places high demands on the flexibility and adaptability of the hydraulic system. Steel wire braided high-pressure resin hose has become an ideal choice for mining machinery hydraulic systems due to its wear resistance and high pressure resistance.
Oil drilling equipment: The working conditions of oil drilling equipment are extremely complex and often require continuous operation in harsh environments such as high pressure, high temperature, and heavy pollution. With its excellent pressure carrying capacity and chemical stability, high-pressure resin hose can effectively solve the problems in hydraulic oil transportation and improve the overall stability and work efficiency of drilling equipment.
Hydraulic lifts and agricultural and construction machinery: In these equipment, steel wire braided high-pressure resin hoses play a vital role as lubrication lines, blowout preventer control lines, etc.
4. Precautions
When using steel wire braided high-pressure resin hose, you need to pay attention to the following points:

Select the appropriate hose specification: Select the appropriate hose inner diameter, outer diameter and working pressure level based on the pressure, temperature, flow rate and other parameters of the conveyed medium.
Regular inspection and maintenance: Check the hose regularly to ensure that there is no damage or aging on the surface, and replace damaged hoses in a timely manner.
Correct installation and use: During installation and use, relevant operating procedures should be followed to avoid excessive bending, stretching or extrusion of the hose.
In summary, steel wire braided high-pressure resin hose has significant advantages and broad application prospects in transporting petroleum-based hydraulic oil. With the continuous development of industrial technology, the performance of this hose will be further improved, providing more reliable and efficient solutions for hydraulic oil transportation in more fields.
