Due to different manufacturing processes and uses of stainless steel pipes, such as surface drawing, pipe bending, environmental impact, etc., the surface of the stainless steel pipe is damaged, which will cause rust. So what methods are used to prevent and delay the rust of stainless steel pipes?
Stainless steel tube core-pulling bending processing effect
Stainless steel passivation liquid is mainly suitable for small and medium stainless steel workpieces with large batches, large output and convenient soaking; such as screws, communication equipment parts, stainless steel precision castings, small furniture, food machinery, digital electrical parts, hardware parts, etc. The method is simple to use at room temperature (More than 15℃) soaking is enough, the operation method is as follows:
1.Degreasing and degreasing, clean the surface of the workpiece to ensure that there is no oil stain;
2.Activate, soak the workpiece in passivation solution for 2-5 minutes to remove rust, wax, welding spots and other impurities on the surface of the workpiece. Rinse the workpiece with clean water;
3.Passivation, soak the workpiece in the passivation solution for more than 30 minutes. The longer the passivation film is, the more complete the passivation film, the stronger the anti-rust ability;
4.With pure water, rinse with clean water for more than 3 minutes, and then dry or let it dry.
