Stainless steel flange

Stainless steel flange is also called stainless steel flange or flange. It's a part that connects pipes to pipes. Connect to the end of the pipe. There are holes in the stainless steel flange, and bolts can be pierced to make the two stainless steel flanges close together. Stainless steel flanges are sealed with gaskets. Stainless steel flange is a kind of disc-shaped parts, which is most common in pipeline engineering. Flanges are used in pairs. In pipeline engineering, flange is mainly used for pipeline connection. In the pipeline that needs to be connected, a flange can be installed in all kinds. The low pressure pipeline can use the wire flange, and the welding flange can be used under pressure of more than 4 kilograms.
The corrosion resistance of stainless steel flange depends on chromium, but because chromium is one of the components of steel, the protection methods are different. The atmospheric corrosion resistance of steel increases significantly when the chromium content reaches 11.7%, but it is not obvious when the chromium content is higher. The reason is that when chromium is used to alloying steel, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which the natural luster of steel surface can be seen, so that stainless steel has a unique surface. Moreover, if the surface layer is damaged, the exposed steel surface will repair itself with atmospheric reaction, and the oxide "passivation film" will be formed again, which will continue to play a protective role. Therefore, all stainless steel elements have a common characteristic, that is, the chromium content is more than 10.5%.
Stainless steel flange connection is easy to use and can withstand greater pressure. Stainless steel flange connections are widely used in industrial pipelines. In the family, the pipe diameter is small, and is low pressure, stainless steel flange connection can not be seen. If in a boiler room or production site, stainless steel flanged pipes and equipment are everywhere.
