1. Clean directly.
If it is dust, oil and other substances, organic solvents can be used to clean the surface of the seamless steel pipe. But this can only be used as an aid to other rust removal methods, and cannot directly remove rust, scale and other substances on the steel surface.
2. Pickling with chemical agents.
Cleaning with chemicals can effectively remove the rust on the seamless steel pipe and ensure a certain cleanliness on the surface, but it will cause serious environmental pollution.
3. Polishing and grinding.
If there is a large area of rust, the seamless pipe manufacturer can use professional tools to remove the rust, and use mechanized equipment to precisely polish the rust position. In addition to eliminating oxidizing substances, it can also make the casting reach a smooth plane.
Any rust removal method may cause large or small damage to carbon steel pipes. Although effective rust removal methods can prolong the service life of seamless steel pipes, it is best to pay attention to the storage of seamless steel pipes from the beginning. Pay attention to the ventilation, temperature and humidity of the location, and follow the relevant storage standards, which can greatly reduce the possibility of rust on the seamless steel pipe.
How to prevent carbon steel pipes from rusting?
1. To protect steel pipes from moisture, especially seawater and rainwater, it can be coated with waterproof paint or paint.
2. Regularly clean and maintain the steel pipe to remove dirt and rust on the surface, and professional cleaning and care agents can be used.
3. During the storage and use of steel pipes, care should be taken to avoid collisions and frictions, so as not to damage the protective layer on the surface.
4. For steel pipes exposed to the air for a long time, they can be treated with preservatives to increase their oxidation resistance and corrosion resistance.
5. Coating a layer of antirust agent on the surface of the steel pipe can effectively prevent the steel pipe from rusting.
