Why does the stainless steel heat exchange tube rust? Stainless steel heat exchange tubes have certain corrosion resistance and will not rust easily. So what is the reason if it rusts?
A more direct factor is the presence of chloride ions in the use or storage environment of stainless steel heat exchange tubes.
Chloride ions exist widely. Chloride ions are found in common things such as table salt, sea water, sea breeze, sweat stains, and soil. Then, if the stainless steel heat exchange tube is exposed to chloride ions for a long time, it will cause corrosion, and the speed is very fast, even exceeding that of ordinary low carbon steel.
Therefore, when we use and store stainless steel heat exchange tubes in our daily life, we should always wipe the surface of the heat exchange tubes to keep them clean, avoid rusting as much as possible, and prolong the service life of the heat exchange tubes.
