Suggestions for treating corrosion of 316 stainless steel welded pipe
316 stainless steel welded tube surface deposits of deposits containing other metal elements of dust or heterogeneous metal particles in the humid air, the condensate between the attachment and stainless steel, the two connected into a micro-cell, triggering the electrochemical reaction, protective film damaged, called electrochemical corrosion. Organic stainless steel tube surface adhesion of organic juice (such as vegetables, noodles soup, sputum, etc.), in the case of water oxygen, organic acids, organic acids for a long time on the metal surface corrosion. Stainless steel pipe surface adhesion contains acid, alkali, salt substances (such as the renovation of the wall of alkali water, lime splashing), causing local corrosion. In polluted air (such as a large amount of sulfide, carbon dioxide, nitrogen oxides in the atmosphere), the case of condensate, the formation of sulfuric acid, nitric acid, acetic acid point, causing chemical corrosion. The above situation is caused by t...
