Precision aluminum tube is widely used in industry, we often ignore the surface treatment in the process of use, in fact, the surface treatment process of precision aluminum tube has been completed by the manufacturer before leaving the factory, this article will introduce the surface treatment process of precision aluminum tube:

1. Precision aluminum tube oil and degreasing

Precision aluminum tube surfaces must be degreased before passivation and pickling, and further components must be welded in the degreasing line to avoid carbon from the pickers at high temperatures.

2. Precision aluminum pipe passivation

Passivation process can only deal with precision aluminum tube and stainless iron with precise surface. The primary purpose of passivation of fine bright tube is to avoid surface oxidation and corrosion of precision aluminum tube.

3. Precision aluminum tube pickling

The purpose of pickling precision aluminum tubes is to remove the oxide skin on the surface of precision aluminum tubes after high temperature welding, heat treatment or hot working. It can also achieve the purpose of eliminating red rust corrosion of steel or iron or steel particles. However, attention should be paid to cleaning the acid on the surface of the precision aluminum tube in time after pickling, otherwise the surface of the aluminum tube will soon begin to rust and corrosion. The corrosion resistance of the surface layer of the aluminum tube below is decreased.

The above is a summary of the precision aluminum tube surface treatment process for you. If you have more relevant knowledge, you can contact us.
