Installation and connection of stainless steel flange and its characteristics
Abstract: The connection of stainless steel flange is easy to use, it’s able to withstand large pressure. Stainless steel flange connections are widely used in industrial pipe. In the family, the pipes’ diameter is small, we can not see the stainless steel flange connection. But if you are in a boiler room or in the production site, stainless steel flange connections are everywhere.
Flange is a connection part between the pipe and pipe. Flange is connected to the pipe end. Stainless steel flange has some holes used to put bolt, which makes two flanges connect tightly. Flanges use gasket to seal up. Stainless steel flange is a kind of disc shaped parts, which is used in pairs. It is very common used in pipeline engineering. In the pipeline project, the flange is mainly used for the connection of pipes. In connection with the pipeline, the installation of a flange plate, low pressure pipe can use wire connection flange, 4 kg or more pressure can use welding flange.
The corrosion resistance of the stainless steel flange depends on the chromium, but because the chromium is one of the components of the steel, so the protection method is not the same. The corrosion resistance of the steel was significantly increased when the chromium content was above 11.7%, but the chromium content was much higher, although the corrosion resistance was still increased, it was not obvious. The reason is that the type of oxide on the surface of the steel is changed into a kind of surface oxide which is similar to the pure chromium metal. This close adhesion chromium oxide protection surface, which prevents further oxidation. This oxide layers is very thin, through which you can see the natural luster of steel surface, which makes the stainless steel has a unique surface. If the surface damage to the surface, the exposed steel surface and atmospheric reaction for self repair, re formed the oxide passivation film, continue to play a protective role. Therefore, all of the stainless steel elements have a common characteristic, that is, the chromium content in more than 10.5%.
Stainless steel flange connection is easy to use. It is able to withstand greater pressure. Stainless steel flange connections are widely used in industrial piping. In the family, the pipe diameter is small, moreover is the low pressure, can not see the stainless steel flange connection. If you are in a boiler room or in the production site, stainless steel flange connections are everywhere.
