Proper cleaning and maintenance of steel pipes involve specific methods to ensure their longevity and performance. Here’s how to clean and maintain steel pipes effectively.


Mechanical Cleaning

- Surface Polishing: Use tools such as wire brushes to polish the surface of steel pipes, removing loose scale, rust, and welding slag.

- Tool Efficiency:

Hand Tools: Can achieve rust removal to Sa2 level.

Electric Tools: Can reach rust removal to Sa3 level.

- Limitations: If the surface of the steel pipe has strong oxide scale, tools may not effectively remove rust or achieve the necessary anti-corrosion depth required for construction.


Chemical Cleaning

- Pickling:

- Solvents and Emulsions: Used to clean the surface of low-pressure welded steel pipes, removing oil, grease, dust, lubricants, and similar organic matter.

- Limitations: Pickling cannot remove rust, oxides, or welding residues on the surface, making it unsuitable for anti-corrosion purposes. It is primarily used as an auxiliary method in production.


Rust Removal Methods

- Chemical and Electrolytic Pickling: Generally used to treat pipe corrosion by removing the oxide layer, rust layer, and old coatings. Sandblasting may also be used before treatment.

- Chemical Cleaning: Achieves a certain level of surface cleanliness and roughness, but the anchor lines are shallow and prone to accumulation, potentially causing environmental pollution.


Principles and Methods

- Strict Adherence: During the cleaning process, follow certain principles and methods strictly to ensure the steel pipes maintain their value and performance in use.

- Environmental Considerations: Chemical cleaning, while effective, should be managed to minimize environmental pollution.



- Long-Term Service: Proper cleaning and maintenance ensure that steel pipes serve effectively in production for an extended period.

- Production Efficiency: Maintaining clean and well-maintained pipes contributes to better production outcomes and increased benefits.


By using a combination of mechanical, chemical, and electrolytic methods, you can effectively clean and maintain steel pipes, ensuring their durability and performance in various applications.
