Stainless steel flanges are most commonly used in pipe engineering. Pipe flanges are generally hard. Most of them are quenched, so they are generally resistant. Therefore, they are very suitable for use in pipeline applications. The hardness of stainless steel flanges is generally 30. Too many, under normal circumstances, stainless steel flanges will be quenched, because its chromium content is 0.1% to 0.5% (stainless steel flanges generally do not contain chromium), carbon content is below 1.0% and stainless steel flanges are used. Made of high temperature stainless steel, some stainless steel flange flange thread appearance hardness (HRC) can reach ≥ 56 or more (the quenching layer is only about 15mm).
The effect of the stainless steel flange is mainly reflected in the link between the two pipes, which is shared with everyone here. The stainless steel flange connection is to fix the two pipes, pipe fittings or components on a flange, and between the two flanges, and the flange pads are fastened together by bolts to complete the connection. Some fittings and components are now self-contained with flanges and are also flanged. The flange end connection of stainless steel flange is an important connection method for pipeline construction. The stainless steel flange is easy to connect and can accept large pressure.
In industrial pipes, the stamping elbows that are connected by stainless steel flanges are widely used. In the home, the pipe diameter is small and low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged flange tubes and devices everywhere. In addition, the stainless steel flanged pipe fittings have high requirements on the welding flange welding rod, and have excellent corrosion resistance and oxidation resistance. It is widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.
