Cangzhou flat flange manufacturer introduced that flat flange, also known as stainless steel flat welding flange, plate flat welding flange or lap welding flange, is a disc-shaped part, usually used in pairs. The flange connection method is to fix two pipes, pipe fittings or equipment on a flange, and then add a flange pad between the two flanges and fasten them together with bolts to complete the connection.
Cangzhou Flat Flange ManufacturerIntroduction, flat flange, also known as stainless steel flat welding flange, plate flat welding flange or lap welding flange, is a disc-shaped part, usually used in pairs. The flange connection method is to fix two pipes, pipe fittings or equipment on a flange, and then add a flange pad between the two flanges and fasten them together with bolts to complete the connection.
The nominal pressure range of flat flange is usually between 0.25MPa and 42.0MPa. The standard system includes two series: the main series is PN1.0. PN1.6. PN2.0. PN5.0. PN10.0. PN15.0. PN25.0. PN42. And series 2 is PN0.25. PN0.6. PN2.5. PN4.0. Among them, 6 grades of flange sizes belong to the European flange system represented by German flange, and the rest belong to the American flange system represented by American flange.
In terms of material, flat flanges can be divided into carbon steel flat flanges, stainless steel flat flanges and alloy steel flat flanges. According to the pipeline pressure to be faced, the diameter and thickness of the flange will be different. Generally, the greater the pressure, the thicker the stainless steel flange. For some pipes that need to face high pressure, it may be necessary to connect stainless steel flanges by welding to ensure that the connection is more firm and reliable.
Cangzhou flat flange manufacturer said,In the process of production and use, it is also necessary to consider the structural form of the flange, including the integral flange and the unit flange. At the same time, during the installation and adjustment process, it is necessary to leave an appropriate gap between the inner diameter of the small-diameter flange and the pipe, and the gap left by the large-diameter flange will be relatively larger to facilitate installation and adjustment.
In short, as an important pipe connection component, flat flange has the advantages of simple structure, convenient use and reliable connection, and has been widely used in petroleum, chemical, electric power, metallurgy and other industries.
