The main components of carbon steel pipes are carbon and iron, and iron will undergo an oxidation reaction under the action of oxygen and water to form iron oxide, which will cause rust. If carbon steel pipes do not take appropriate protective measures during transportation, storage and use, they are easily corroded and eroded by air, water, oxides and other pollutants, leading to rust. This article will talk about how to treat carbon steel pipe rust.
Rust Treatment Of Carbon Steel Pipes
1) Mechanical treatment
Mechanical treatment include scraping rusty areas with steel brushes, sandpaper, scrapers, etc. to achieve the purpose of removing the rust layer. However, it is important to note that mechanical treatment methods are only suitable for light rust or surface rust. If the degree of rust is severe, mechanical treatment can only provide temporary control.
2) Chemical treatment
Chemical treatment mainly uses some chemical methods to dissolve or transform rust to achieve the purpose of removal. The more commonly used chemical treatment methods include pickling, alkali washing, electrolysis, impregnation, etc. It should be noted that although chemical treatment can remove rust more thoroughly, its operation is more complicated and it can easily cause damage to the pipeline. It also requires strict safety and environmental measures.
3) Anti-rust paint
The anti-rust paint method is to spray or brush a certain amount of anti-rust paint on the surface of the carbon steel pipe to prevent oxygen and water from contacting the metal, thereby acting as an isolation and reducing or avoiding the impact of metal rust. The anti-rust paint method is relatively simple, easy to use and widely used. However, this method still has shortcomings such as easy falling off and easy deformation when heated.
Conclusion:
Rusting of carbon steel pipes is a common problem, but we can deal with and prevent this situation through the above methods. At the same time, we must also choose appropriate treatment methods based on the actual pipeline conditions to ensure the safety and reliability of the pipeline.
