How to maintain the smoothness of galvanized steel pipe intact

Galvanized steel pipes have been widely used in construction materials due to their superior quality and performance. In order to achieve more efficient operation and laying efficiency, galvanized steel pipes tend to adopt some unique methods of production and work.
Post-treatment of galvanized steel pipe includes passivation, pre-phosphating and oiling. Passivation treatment can improve the gloss of the galvanized steel pipe surface and improve its overall wear resistance to improve the service life, the most important point is that To improve the combination with other base metals, at present, when passivating galvanized steel pipe, chromate is mainly used for passivation, and some activators such as fluoride, phosphoric acid or sulfuric acid can be added during passivation to make After passivation thicker chromate film. When the passivation solution of fluoride can reduce the surface tension of the steel, accelerate the film reaction, and can increase the role of chemical polishing, the passivation film is fine and bright.
Galvanized steel pipe not only in production, pay attention to the relevant production process, but also in the latter part of the processing and processing technology to be accurate, so that you can give the product double insurance, making galvanized steel not only in appearance On the quality is still a higher level, has become a strong application of reliable building materials.
