About the passivation of the stainless steel pipe fittings

　　In our today's career stainless steel pipe fittings used to say very much, but you know that just get its hands on stainless steel pipe fittings is put into immediately to use oh, you know to forefathers sex passivation disposal? Any stainless steel parts, if no plating or other coating request, ordinary

　　At pre treatment (including pickling to black, polishing, etc.) through the passivation disposal, talents when products or disassembled into parts. Thermodynamics can be improved after passivation of stainless steel in medium volatility, prevention of stainless steel parts of the corruption, make stainless steel appearance has enough clean degree

　　And can also eliminate stainless steel exterior thermal oxide. The passivation technology of stainless steel can be divided into wet and dry process two kinds. Detailed and type can be divided into many varieties.

　　Here are bolden stainless steel pipe fittings for everybody introduced next wet down the pickling passivation operation method:

　　Washing is applied chemistry reaction in workpiece melting appearance lost rust, oxidation film, and other products, this method does not affect the matrix metal, the goal is to make the workpiece surface decontamination, to reach the goal of pollution. Passivation is the application of chemical reaction, in workpiece appearance constitute a dense oxide film

　　Methods. The goal is to make the workpiece appearance set oxide film or oxygen adsorption layer, thereby blocking electrochemistry corrupting stop, and progress of metal corrosion (electrochemical corrupt) function.
