When you use stainless steel heat exchange tubes, have you ever encountered rust on the tubes? The reasons for the rusting of stainless steel heat exchange tubes are not uniform. There are many factors that may cause it to rust. Therefore, Mingxin Stainless Steel finds out several common factors. Let’s take a look below.
1. The effect of organic matter juice
The surface of the stainless steel heat exchange tube adheres to some organic juices like melons and noodle soup, which will form organic acids under the action of water and oxygen, which will corrode the surface of the stainless steel heat exchange tube over time.
2. Affected by air pollution
In the environment where the stainless steel heat exchange tube is stored, the air contains a large amount of sulfide or carbon oxide, oxidative inflammation, etc., and the condensed water forms sulfuric acid, nitric acid, and acetic acid spots, which will cause chemical corrosion and rust.
3. Effect of acid, alkali and salt
The surface of the stainless steel heat exchange tube is in contact with acid, alkali and salt substances, which will cause local corrosion and rust.
4. Effect of electrochemical corrosion
Dust containing other metal elements or heterogeneous metal particles is deposited on the surface of the stainless steel heat exchange tube. When the air is humid, the condensed water between the attachment and the stainless steel will connect the two into a miniature battery, causing electrochemical corrosion.
These are the common factors that cause stainless steel heat exchange tubes to rust, you can find out!
