Stainless steel flange installation and quality features

2019-07-05 16:45:13

Stainless steel flange, which is called stainless steel flange, or flange. It's a part of a pipe that connects to a pipe. Connect to tube end. The stainless steel flange is perforated and bolts can be threaded to tighten the two stainless steel flanges. Stainless steel flanges are sealed with gasket. Stainless steel flange is a kind of disc-shaped parts, common in pipeline engineering, flanges are used in pairs. In pipeline engineering, flanges are mainly used for pipe connection. In the need to connect the pipeline, all kinds of installation of a flange, low-pressure pipeline can use wire flange, 4 kg above the use of welding flange.

Stainless steel flange corrosion resistance depends on chromium, but because chromium is one of the components of steel, so protection methods are not the same. When the chromium content reaches 11.7%, the atmospheric corrosion resistance of steel increases significantly, but when the chromium content is high, the corrosion resistance can still be improved, but it is not obvious. The reason is that when the steel is alloyed with chromium, the type of surface oxide changes to a surface oxide similar to that formed on a pure chromium metal. This tightly adhering chrome-rich oxide protects the surface from further oxidation. This oxide layer is extremely thin, through which you can see the natural luster of the steel surface, giving stainless steel a unique surface. Moreover, if the surface is damaged, the exposed steel surface reacts with the atmosphere to repair itself, reforming the oxide "passivation film" that continues to protect. Therefore, all the stainless steel elements have a common characteristic, that is, the content of chromium in 10.5% or more.

Stainless steel flange connection easy to use, can withstand greater pressure. Stainless steel flanges are widely used in industrial pipelines. In the home, the pipe diameter is small, and is low pressure, can not see the stainless steel flange connection. If you are in a boiler room or production site, there are stainless steel flanged pipes and equipment everywhere.
