1. Reasons why carbon steel tubes rust
The reason why carbon steel tubes
rust easily is that their main components are carbon and iron. Iron will undergo an oxidation reaction under the action of oxygen and water to form iron oxides, which will cause rust. However, if protective measures are not taken during transportation, storage and use of carbon steel tubes, they will be easily corroded and eroded by air, water, oxides and other pollutants, causing rust.
2. How to deal with rusty carbon steel tubes
1) Mechanical treatment method
Mechanical treatment methods include scraping the rusted areas with steel brushes, sandpaper, scrapers, etc., to achieve the purpose of removing the rust layer. However, it should be noted that the mechanical treatment method is only suitable for mild rust or surface rust. If the degree of rust is serious, mechanical treatment can only play a temporary control role.
2) Chemical treatment method
Chemical treatment methods mainly use some chemical methods to dissolve or transform rust to achieve the purpose of removal. The more commonly used chemical treatment methods include acid washing, alkali washing, electrolysis, dipping, etc. It should be noted that although chemical treatment can remove rust more thoroughly, its operation is more complicated and can easily cause damage to pipes. It also requires strict safety and environmental protection measures.
3) Anti-rust paint method
The anti-rust paint method is to spray or brush a certain amount of anti-rust paint on the surface of carbon steel tubes to prevent oxygen and water from contacting the metal, thereby acting as an isolation to reduce or avoid the effect 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 due to heat.
3. Future preventive measures
1) Do a good job of protection
During the transportation, storage, installation and use of carbon steel tubes, protective measures should be taken, such as avoiding carbon steel tubes from direct contact with the ground and water sources as much as possible, choosing a suitable storage environment, and isolating different types of carbon steel tubes and cleaning them regularly. etc.
2) Select carbon steel tubes with reliable quality
When purchasing carbon steel tubes, you must pay attention to the quality of the product and choose manufacturers and products with reliable quality to ensure its corrosion resistance and service life.
Rusting of carbon steel tubes is a common problem, but we can deal with and prevent this situation through the above methods to ensure the safety and reliability of the pipeline. In actual application, it is necessary to analyze the specific situation and select the appropriate treatment method according to the pipeline conditions.
