Stainless steel butterfly valve protective film damage will lead to rust introduction

The surface of the stainless steel butterfly valve contains dust or particle deposits of other metal elements. In the humid air, electrochemical reaction occurs, which causes the surface protection film of the stainless steel butterfly valve to be damaged. The surface of the stainless steel butterfly valve contains acid, alkali, salt, etc. A substance that causes local corrosion of the metal. Stainless steel butterfly valve in the polluted air, the metal surface will encounter condensed water, and the formation of sulfuric acid, nitric acid, acetic acid liquid point, causing chemical corrosion. The surface of the stainless steel butterfly valve is adhered to the organic juice slurry. In the case of water and oxygen, the organic acid will corrode the metal surface for a long time.

  Stainless steel butterfly valve has good wear resistance and corrosion resistance, so stainless steel butterfly valve can resist oxidation in the atmosphere, and it can also have good corrosion characteristics in some media such as salt, alkali and acid. Although these characteristics can well reflect the advantages of the stainless steel disc valve, it is formed by a very thin and strong protective film on the surface to prevent oxidation. In some special environments, the protective film will be damaged, so that the metal surface will be affected. Constant rust. It is recommended that you regularly clean the surface of the butterfly valve and remove some attachments to better protect the stainless steel butterfly valve to improve the service life.
