How to correctly place 304 stainless steel pipe 2018-11-02 304 stainless steel pipe not only needs attention in the production process, but also cannot be ignored in the placement process. Do you know how to place 304 stainless steel pipes correctly? 1. 304 stainless steel pipes and carbon steel pipes cannot be stacked together, because the materials of carbon steel pipes and stainless steel pipes are different. In a humid environment, if the carbon steel pipes and stainless steel pipes are stacked together, a chemical reaction will easily occur. , And then damage the protective layer of the stainless steel pipe, causing the stainless steel pipe to rust. 2. If different steels are piled together and contact each other, a potential difference will occur, which will cause galvanic corrosion, especially when the water accumulates, the speed of galvanic corrosion between stainless steel pipes and carbon steel pipes will accelerate. 3. Just like the principle of the battery, the chemical energy in the chemical battery is directly converted into electrical energy because of the oxidation recovery reaction inside the battery. In order to prevent electrochemical corrosion and carburization of stainless steel pipes, try not to stack the two together. However, when the countersunk head is in contact between carbon steel and stainless steel at room temperature, carburization will not occur immediately. The colorful rust on the 304 stainless steel pipe will only appear in a certain period. The 304 stainless steel pipe should be placed in a clean and ventilated environment and cleaned up in time.
