Do Hydraulic Pipes Need To Be Pickled?

Pickling is mainly suitable for metal pipes such as steel pipes and cast iron pipes. It can effectively remove impurities and rust on the inner wall of the pipe, making its surface smoother and more delicate, and improving the efficiency of the pipeline to transmit liquid. The hydraulic pipes are pipes used to transport liquid or convert liquid into mechanical energy. Hydraulic pipe is one of the seamless steel pipe. Hydraulic pipes must be pickled before use, because pickling can effectively remove impurities and rust on the inner wall of the pipe, ensuring the cleanliness and service life of the pipe.

 

The process of pickling hydraulic pipes

During the production process of hydraulic pipes, due to material reasons or friction during processing, there will be some impurities such as rust, steel slag, and scrap iron on the surface of the pipe. These impurities will have a certain impact on the service life and use effect of the pipe, so the pipe needs to be pickled.

The process of pickling hydraulic pipes includes the following steps:

1. Cleaning: First clean the surface of the hydraulic pipe with clean water or cleaning agent to remove most of the dust and impurities.

2. Pickling: In a specific acidic environment, soak the hydraulic pipe for a period of time so that the rust, steel slag, scrap iron and other impurities on the surface of the pipe are dissolved and removed by acid.

3. Cleaning: After pickling, the hydraulic pipe needs to be thoroughly cleaned with clean water, and alkali solution is used to neutralize the residual acidity to avoid affecting the service life of the pipe.

 

The role of hydraulic pipe pickling

The main role of hydraulic pipe pickling is to remove impurities on the surface of the pipe, improve the smoothness and roughness of the pipe surface, reduce the resistance inside the pipe, and thus improve the use effect and service life of the hydraulic pipe.

In addition, the hydraulic pipe treated with pickling also has the following characteristics in the later use process:

1. The surface of the pipe is smooth, and it is not easy to adhere to dirt and impurities, which is convenient for cleaning and maintenance.

2. The inner wall of the pipe is smooth and the friction coefficient is small, which can effectively reduce the pressure loss and energy consumption of the pipe.

3. The flatness and straightness of the pipe surface are increased, which can ensure the smooth and stable flow of liquid or gas, and is conducive to industrial automation control.

 

The necessity of pickling hydraulic pipes

1. Ensure the normal operation of the hydraulic system: The low finish of the inner wall of the pipe will have a great impact on the operation of the hydraulic system. For example, sediments will increase the friction resistance of the pipe, reduce the transmission flow, and even cause the pipe to be blocked; while oxides will damage the structure of the pipe and cause leakage.

2. Extend the service life of the hydraulic system: The inner wall of the pipe treated with pickling is smoother, which can prevent scale, corrosion and rust, thereby extending the service life of the pipe.

 

The impact of not pickling the pipe

1. Increased resistance: Impurities and rust on the inner wall of the pipe without pickling are difficult to remove, which will increase the resistance of the pipe and reduce the efficiency of transmitting fluid.

2. Leakage: The unpickled part of the inner wall of the pipe is prone to oxides and rust, which may cause the pipe to age and crack, thus causing leakage.

 

Conclusion

Hydraulic pipes must be pickled before use. Only by thoroughly cleaning the impurities and rust on the inner wall of the pipe can the finish and smoothness of the pipe be guaranteed, and the efficiency of transmission flow and fluid can be improved, thereby ensuring the normal operation of the hydraulic system and extending its service life.
