Seamless square pipes are part of the lack of engineering buildings. Therefore, the quality of seamless square tube quality will immediately affect the development trend of the construction industry. How can we make the service life of seamless square pipes longer?
The first way is to carry out rust -proof treatment of seamless square tube. When giving the seamless square tube anti -rust treatment, the key uses steel brush to carry out polishing and polishing on its surface. The rust of loose or tilted.
The second method is to clean up the surface layer of the seamless square tube. When cleaning the seamless square tube, use organic solvents or solvents to clean the surface layer to achieve the role of oil removal and dust removal. The method is only suitable for the plant oil and dust of the surface of the seamless square tube to rust and the oxide skin. Therefore, in the anti -corrosion manufacturing, this method can only be used as an auxiliary method.
The third method is to carry out pickles and passivation to seamless square tubes. When carried out pickup and passivation of seamless square tubes, they will use organic chemistry and electrolytic methods. These two methods will be The oxide skin of the seamless square pipeline is eliminated. It is often divided into two ways. Because of the chemical water treatment, it can only clean the surface layer very complete, and it is difficult to achieve in some gaps.
After the organic chemical acid washing and passivation, the filling method can be carried out by an electrolytic method to allow the seamless square tube to be well maintained.
