The stainless steel pipe elbow has excellent corrosion resistance, thin stainless steel surface and strong oxide film, so that all stainless steel has excellent corrosion resistance in all water quality, even if buried also has excellent corrosion resistance. Therefore, it is suitable for various water quality. Besides disinfection and sterilization, it does not need to control the water quality. At the same time, there is no corrosion and excess exudation, the water quality is kept clean, two pollution is prevented, and the high water flow rate of up to 30 meters per second can be affected.
Many people think that stainless steel is not rust steel, of course. The stainless steel pipe elbow anti rust mechanism is to form compact alloy oxide film, isolate oxygen contact and prevent oxidation. So stainless steel is not "stainless steel". Stainless steel has the ability to resist atmospheric oxidation, that is, stainless steel, and has corrosion resistance in acid, alkali and salt media, that is, corrosion resistance. After the Prime steel pipe, the main factors affecting the corrosion of stainless steel are understood.
The content of 1. alloy elements. Generally speaking, chromium content in 10.5% steel is not easy to rust. The higher the content of chromium and nickel, the better corrosion resistance. If the nickel content of 304 material is 8-10% and the chromium content is 18-20%, the angle of the 304 stainless steel is generally not rusty.
2. the manufacturing enterprises in the smelting process will also affect the corrosion resistance of stainless steel. The large 304 stainless steel corner steel plants with good smelting technology, advanced equipment and advanced technology are guaranteed to control alloy elements, remove impurities and control the cooling temperature of steel billet, so the quality of the products is stable and reliable, the internal quality is good, and the rust is rusty. On the contrary, some small steel mills are backward in equipment and backward in technology. Impurities can not be removed during the smelting process, and the products produced will inevitably become rusty.
4. external environment, dry climate, ventilation environment is not easy to rust. Moreover, air humidity, continuous rainy weather or air containing highly acidified environment are easy to rust. 304 stainless steel angle stainless steel, if the surrounding environment is too bad will rust.
In addition, stainless steel pipe elbow has rust point, indicating that elbow is not made of pure stainless steel, it is the type of stainless steel elbow. Rust spots can be ground with super fine sandpaper, and bright colourless paint can be used for rust treatment. If the rust point is not treated, these rust spots will gradually expand, affecting appearance and shortening elbow life.
1. the use of environmental chlorine ions. Chloride exists widely, such as salt, sweat, sea water, sea breeze, soil and so on. The presence of chloride ions in the environment of stainless steel corrode rapidly, even more than ordinary low carbon steel. Therefore, the use of stainless steel elbow fittings is necessary, but also need frequent wipe, remove dust, keep clean and dry.
