Flanges are components used to connect shafts to shafts, or to connect pipe ends; there are also flanges used at equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. Flange connections or flange joints refer to the detachable connections formed by the combination of flanges, gaskets, and bolts as a group of sealing structures, also known as flange hubs or bosses.
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 disks and then secure them with bolts. Flanges of different pressure ratings have varying thicknesses and require different bolts.

1. Divided according to the chemical industry (HG) standard:
Overall Flange (IF), Threaded Flange (Th), Plate Flange (PL), Weld Neck Flange (WN), Socket Weld Flange (SO), Lap Joint Flange (SW), Blind Flange (PJ/SE), Flat Ring Blind Flange (PJ/RJ), Lined Flange Cover (BL(S)), Flange Cover (BL).
2. Divided by petrochemical (SH) industry standards: Threaded Flange (PT), Weld Neck Flange (WN), Slotted Flange (SO), Socket Weld Flange (SW), Lug Flange (LJ), Flange Cover (not specified).
3. Divided according to the JB mechanical industry standard: Full Flange, Weld Neck Flange, Plate Welding Flange, Weld Neck Plate Flange with Loose Fit, Flat Weld Plate Flange with Loose Fit, Bevelled Edge Plate Flange with Loose Fit, Flange Cover.
4. Categorized by national (GB) standards: Weld Neck Flanges, Threaded Flanges, Socket Weld Flanges, Slab Weld Flanges, Socket Welding Flanges with Neck, Flanges with Weld Ring and Socket Type Neck, Plate Flange with Weld Ring, Plate Flange with Socket Type, Flat Ring Plate Flange with Socket Type, Flanged Ring Plate Flange with Socket Type, and Flange Cover.
