Corrosion resistance of Stainless Steel Weld Tee

When using stainless steel tees, people will find that after a long period of use, spots or even cracks will appear on the surface of the stainless steel tees. What's going on?

This is caused by the corrosion of stainless steel. Many people think that stainless steel is stable and will not be corroded. In fact, it is not the case. The corrosion resistance of stainless steel does not mean that it will not be corroded. Stainless steel tees are often used for the transportation and distribution of tap water and other media in daily life. Water itself is corrosive to metals. In addition, the corrosive impurities in the liquid will continuously destroy the passivation film on the steel surface during long-term transportation, thus causing corrosion of the stainless steel tee.

The initial manifestation of corrosion is the appearance of spots on the surface of stainless steel. When spots appear, it indicates that the material of the stainless steel tee has been damaged, and then it will accelerate the corrosion of stainless steel and cause cracks in the pipeline. Therefore, in daily life, we must understand that stainless steel tees are corrosion-resistant, but not uncorroded. During use, especially for tees that have been used for a certain number of years, they must be checked in time to avoid causing greater damage.
