How to maintain the integrity of seamless steel pipes?
The application range of seamless steel pipes is becoming wider and wider. In the whole process of applying seamless steel pipes, how should people keep the level of seamless steel pipes unchanged?
The post-production of seamless steel pipes includes passivation treatment, pre-phosphating treatment, and oiling. According to the passivation treatment plan, the gloss and overall wear resistance of the seamless steel pipe surface layer can be improved, thereby prolonging the service life.
The key is that it can improve the integration with other conventional metal materials. At this stage, for the stainless steel passivation of seamless steel pipes, the key to using chromate for passivation is to increase some activation in the case of passivation.
After passivation, reagents such as chloride, ammonium sulfate, or hydrochloric acid will cause the chromate film to thicken. When the passivating agent contains chloride, it can reduce the interfacial tension of the steel chain, accelerate the demulsification reaction, improve the chemical polishing effect, and make the coating delicate and bright.
