A flange is a component that connects two shafts together, used for joining pipe ends; there are also flanges used at equipment inlets and outlets for connecting two devices, such as reducer flanges. Flange connection or flange joint refers to a removable connection consisting of a flange, a gasket, and bolts, which together form a combination sealing structure, also known as a flange boss or rim.
Flange Usage: Flanges are used in pairs. Soldered flanges can be used for low-pressure pipelines, while welding flanges are required for pressures over 4 kg. Place a gasket between the two flange plates and then secure them with bolts. Flanges of different pressures have varying thicknesses and require different bolts.
Classification Methods of Flanges:
1. Categorized according to the chemical industry (HG) standards:
Overall Flange (IF), Threaded Flange (Th), Plate Flange (PL), Socket Welding Flange (WN), Slip-on Flange (SO), Weld Neck Flange (SW), Blind Flange (BL(S)), Ring Type Joint Flange (PJ/SE), Raised Face Ring Type Joint Flange (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. Divided by mechanical (JB) industry standards: Welding Neck Flanges, Blind Flanges, Plate Flanged Welding Flanges, Welding Ring Plate Flanged Slip-on Flanges, Flanged Plate Flanged Slip-on Flanges, Bevelled Ring Plate Flanged Slip-on Flanges, and Flange Covers.
4. Divided by national (GB) standards: whole flange, threaded flange, socket weld flange, blind flange, lug weld flange, ring-type joint flange with neck, flat welding plate flange, ring-type joint plate flange, flat welding ring plate flange, bevelled ring plate flange, and flange cover.
