Although the stainless steel pipe making machine is a material for making stainless steel pipes, the surface of this equipment is also made of stainless steel, so in general it is not easy to rust. If it does rust, there are reasons. Many users Maybe you don't know much about this aspect, so let's listen to how the stainless steel pipe making machine manufacturer introduces to you! I believe you will understand after reading this.
1. The surface of stainless steel adheres to acid, alkali and salt substances (such as alkali water and lime water spray test on the decoration wall) causing local corrosion.
2. In polluted air (atmosphere containing a lot of sulfides, oxides, and hydrogen oxides), contact with condensed water will form nitric acid and acetic acid liquid spots, causing chemical corrosion.
3. Organic juice is adhered to the surface of stainless steel. In the presence of water and oxygen, it forms organic acid, which will corrode the metal surface for a long time.
4. The stainless steel pipe is a steel pipe that does not produce rust in the atmosphere, fresh water and other weak corrosive environments, and the chromium content in the steel must be ≥12%. If the chromium content is low or it is not used in a weakly corrosive environment such as the atmosphere (including in a weakly corrosive environment such as the atmosphere, but under the condition of local enrichment and concentration of Cl-), rust will occur.
5. The surface of stainless steel accumulates dust containing other metal elements or attachments of dissimilar metal particles. In humid air, the condensed water between attachments and stainless steel connects the two into a micro battery, which initiates an electrochemical reaction , The protective film is damaged, which is called electrochemical corrosion.
It is precisely because of these reasons that our stainless steel pipe making machines are rusty. If you encounter these problems, you can look at the above to find the correct solution. If you need to order stainless steel pipes If you have such equipment, you can also contact us directly.
