Information summary：The purpose of precision tube pickling treatment is to remove the oxide skin on the surface of precision tube after high temperature welding, heat treatment or hot processing. It can also achieve the purpose of eliminating red rust corroded steel or iron or steel particle contamination. However, it is necessary to pay attention to cleaning the acid solution on the surface of the precision pipe in
Surface treatment process of precision tube:
1.
Before passivation and pickling treatment, the surface of precision tube must be degreasing and degreasing, and further components must be welded after degreasing treatment to avoid Pick up carbon at high temperatures.
2.
The passivation process of precision tubes and tubes can only deal with precision steel tubes and stainless irons with precise surfaces. The primary purpose of passivation of precision tubes is to avoid oxidation and corrosion of the surface of precision tubes.
3.
The purpose of precision tube pickling is to remove the oxide skin on the surface of the precision tube after high temperature welding, heat treatment or thermal processing. It can also achieve the purpose of eliminating red rust corroded steel or iron or steel particle contamination. However, it is necessary to pay attention to cleaning the acid solution on the surface of the precision pipe in time after pickling, otherwise the surface of the steel pipe will soon begin to rust and corrode. This leads to a decrease in the corrosion resistance of the underlying steel pipe surface.
