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 formed by the combination of flange, gasket, and bolt, also known as a flange boss or rim.

The Use of Flanges: Flanges are used in pairs. Soldered flanges can be used for low-pressure pipelines, while焊接 flanges are required for pressures above 4 kg. Place a sealing gasket between the two flange discs and then secure them with bolts. Flanges of different pressures have varying thicknesses and require different bolts.

Classification methods for flanges:

1. Divided by the chemical industry (HG) standards:

Overall Flange (IF), Threaded Flange (Th), Plate Flange (PL), Weld Neck Flange (WN), Socket Weld Flange (SO), Blind Flange (SW), Ring Type Joint Flange (PJ/SE), Lap Joint Flange (PJ/RJ), Lined Flange Cover (BL(S)), Flange Cover (BL).

2. Divided according to the petrochemical (SH) industry standards: Threaded Flange (PT), Weld Neck Flange (WN), Flat Weld Flange (SO), Socket Weld Flange (SW), Lug Flange (LJ), and Flange Cover (not specified).

3. By mechanical (JB) industry standards: flanged joints, welding neck flanges, plate flat welding flanges, welding neck ring type loose flange, flat ring plate type loose flange, bevel ring plate type loose flange, and flange covers.

4. Divided by national (GB) standards: Flanged joints, Threaded flanges, Weld neck flanges, Socket weld flanges, Blind flanges, Weld ring socket weld flanges, Plate flat weld flanges, Weld ring plate loose fit flanges, Flat ring plate loose fit flanges, Bevel ring plate loose fit flanges, Flange covers.
