Hydraulic oil pipe joints are crucial connecting components in hydraulic systems. They are used to connect hydraulic oil pipes with equipment, valves or other pipelines to ensure smooth transmission of hydraulic oil and stable operation of the system. According to different design standards and application scenarios, hydraulic oil pipe joints can be divided into many types, each of which has its unique advantages and applicable scenarios. Next, Liwang Technology Department will introduce you to the main types and applications of hydraulic oil pipe joints in detail.

 

 

Main types of hydraulic oil pipe joints

 

1. Crimp joints: The joints are tightly combined with the hoses through the crimping process. They have high sealing and anti-pull-off properties. They are suitable for high-pressure and high-vibration environments and are commonly used in engineering machinery and mining equipment.

2. Flange joints: They are connected by flanges and bolts. They are suitable for large-flow, high-pressure hydraulic systems. They are commonly used in petrochemical and shipbuilding.

3. Quick-change joints: Designed as a structure that can be quickly connected and disconnected, it is convenient for equipment maintenance and replacement. It is suitable for agricultural machinery and logistics equipment.

4. Threaded joint: It is connected by threads, with simple structure and low cost, and is suitable for medium and low pressure hydraulic systems, such as industrial equipment and hydraulic tools.

5. Card sleeve joint: The hose and the joint are fixed by the ferrule, which is easy to install and has good sealing performance. It is suitable for small diameter pipelines, such as laboratory equipment and pneumatic systems.

6. Flared joint: The hose end is expanded by the flaring process to form a tight connection with the joint, which is suitable for high pressure systems, such as aerospace and heavy machinery.

7.Cone seal joint: It adopts a conical sealing surface design, has excellent anti-vibration performance, and is suitable for dynamic connection occasions, such as construction machinery and hydraulic drilling rigs.

 

Application scenarios of hydraulic oil pipe joints

 

- Construction machinery: Excavators, loaders and other equipment often use crimping joints and flange joints to ensure efficient power transmission.

- Mining equipment: Hydraulic supports, mining trucks and other equipment require high pressure and wear-resistant joints, and crimping and cone seal joints are ideal choices.

- Agricultural machinery: tractors, harvesters and other equipment often use quick-change connectors and threaded connectors for easy maintenance and operation.

- Petrochemical: Flange connectors and corrosion-resistant connectors are required for high pressure and corrosive media environments.

- Aerospace: The requirements for precision and reliability are extremely high, and flared connectors and cone seal connectors are commonly used.

- Shipbuilding: Corrosion-resistant connectors and flange connectors are required in humid and high-salinity environments.

 

Summary

 

Hydraulic oil pipe connectors are of various types and have a wide range of application scenarios. Choosing the right connector type can significantly improve the performance and reliability of the hydraulic system. Whether it is construction machinery, mining equipment or aerospace, understanding the characteristics and application scenarios of connectors can help you make the best choice.
