Derusting method of seamless steel pipe

Steel refers to a metal material with iron as the main element, carbon content generally below 2.0% and other elements. The difference between it and iron is the carbon content. It should be said that it is tougher and more durable than iron. Although it is not easy to rust, it is difficult to guarantee that it will be corroded. If it is corroded and not treated in time, it will be easily corroded. Lose the functionality it was supposed to have.

When the seamless steel pipe is rusted, what are the usual treatment methods? Some people will use the cleaning method to clean the stainless steel pipe. When cleaning, the surface of the steel should be cleaned with solvent and emulsion first. This method is only used as an auxiliary means of anti-corrosion and cannot really remove the stainless steel pipe. effect of rust. We can also use steel brushes, wire balls and other tools to remove the loose oxide scale and rust on the surface before cleaning, but if we still do not take protective measures, it will be eroded again.

Pickling is also one of the ways to remove rust. Generally, two methods of chemical and electrolysis are used for pickling treatment, and only chemical pickling is used for pipeline anticorrosion. Although this method can achieve a certain degree of cleanliness, it is easy to cause pollution to the environment, so it is not recommended to use it.

Using jet derusting, high-power motor drives jet blades to rotate at high speed, so that abrasives such as steel grit, steel shot, iron wire segment, and minerals are jetted on the surface of stainless steel pipe under the action of centrifugal force. Not only can rust, oxides and dirt be completely removed, but the steel pipe can also achieve the required uniform roughness under the action of the violent impact and friction of the abrasive. Spray rust removal is an ideal rust removal method in pipeline anticorrosion methods. Among them, many physical theories are used, the pollution to the environment is small, and the cleaning is thorough.
