A flange is a component that connects two shafts or serves as a connection between pipe ends; there are also flanges used at equipment inlets and outlets for connecting two devices, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, a gasket, and bolts, collectively forming a combination sealing structure, also known as a flange hub or rim.
The usage of Flanges: Flanges are always used in pairs. For low-pressure pipelines, threaded flanges can be used, while for pressures above 4 kg,焊接 flanges are recommended. Place a sealing gasket between the two flange discs and then secure them with bolts. Flanges of different pressures have varying thicknesses, and they also require different bolts.
Classification Methods of Flanges:
1. Categorized according to the chemical (HG) industry standards:
Overall Flange (IF), Threaded Flange (Th), Plate Flanged Socket Weld (PL), Socket Welding Flange (WN), Lap Joint Flange (SO), Blind Flange (SW), Weld Neck Flanged Loose Socket (PJ/SE), Flat Ring Loose Socket (PJ/RJ), Lined Flange Cover (BL(S)), Flange Cover (BL).
2. Divided according to the petrochemical (SH) industry standards: threaded flange (PT), welding neck flange (WN), flat welding flange (SO), socket welding flange (SW), loose joint flange (LJ), and flange cover (not specified).
3. Categorized by mechanical (JB) industry standards: integral flange, weld neck flange, flat焊接 flange, welding ring loose flange plate, flat焊接 ring loose flange plate, beveled ring loose flange plate, flange cover.
4. Divided by national (GB) standards: Weld Neck Flange, Threaded Flange, Socket Weld Flange, Blind Flange, Lap Joint Flange, Flanged Socket Weld Flange, Plate Flange, Flanged Plate Flange, Flat Flange, Raised Face Flange, and Flange Cover.
