A flange is a component that connects two shafts together and is used for the connection between pipe ends; there are also flanges used at equipment inlets and outlets, such as reducer flanges, for connecting two pieces of equipment. A flange connection or flange joint refers to a removable joint formed by the combination of a flange, a gasket, and bolts, also known as a flange boss or rim.

Flange Usage: Flanges are always used in pairs. Low-pressure pipelines can use threaded flanges, while those above 4 kg pressure require welding flanges. Place a sealing gasket between the two flange plates and then secure them with bolts. Flanges of different pressures have varying thicknesses and require different bolts.

Classification of Flanges:

1. Divided by the industry standards of chemicals (HG):

Overall Flange (IF), Threaded Flange (Th), Plate Flanged Socket Weld (PL), Weld Neck Flange (WN), Socket Weld Flange (SO), Blind Flange (SW), Ring Type Joint Flange (PJ/SE), Ring Type Joint Flange with Flat Face (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: whole flange, weld neck flange, flat welding plate flange, weld ring plate loose flange, flat ring plate loose flange, beveled ring plate loose flange, and flange cover.

4. Divided by national (GB) standards: Flanged joints, Threaded flanges, Weld neck flanges, Socket weld flanges, Blind flanges, Ring-type joint flanges with weld neck, Plate-type flat weld flanges, Ring-type plate joint loose flanges, Flat ring plate loose flanges, Beveled ring plate loose flanges, Flange covers.
