This article mainly talks about the rust removal methods of .
The steel refers to metal materials with iron as the main element and other elements, in which the carbon content generally is less than 2.0%. The difference between seamless steel pipes and iron lies in the content of carbon. The seamless steel pipe is more tough and durable than iron. Although the seamless steel pipe is not easy to rust, it is difficult to guarantee whether it will be rusty or not. Once it is rusty and it is not handled in time, it is easy to rust and its original function will be lost.
When the seamless steel pipe rusts, what are the usual treatment methods? Some people will use the way of cleaning the stainless steel pipes. In the process of cleaning, the solvent and emulsion should first be used to clean the steel surface. Only as a kind of auxiliary means of corrosion, this method can not really play the role of removing the rust of stainless steel pipes. We can also use a steel brush, wire ball and other tools before cleaning the surface of the loose oxide scale and rust removal. However, if the protective measures are not good, the steel will once again rust.
Pickling is also one of the methods to remove the rust. Generally, chemical and electrolytic methods are used for pickling treatment. Chemical pickling is only used for pipeline anticorrosion. Although this method can achieve a certain degree of cleanliness, it is easy to cause environmental pollution. Therefore, it is not recommended that it should be used.
As for the method of shot blasting, the shot blasting is used on the surface of stainless steel. The process is making the steel sand, steel shot, iron wire segment, minerals and other abrasive under the action of centrifugal force by the high-speed rotation of high-power motor driven shot blasting blade. Not only the rust, oxide and dirt can be completely removed, but also the required uniform roughness of the seamless steel pipes can be achieved under the action of the abrasive impact and friction force. The shot blasting is an ideal rust removal method in pipeline anticorrosion. A lot of physical theories are used in order to reduce environmental pollution and clean seamless steel pipes thoroughly.
