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 reducer flanges. A flange connection or flange joint refers to a removable connection formed by the combination of flange, gasket, and bolt, also known as a flange disc or boss.
The usage of Flanges: Flanges are always used in pairs. Low-pressure pipelines can use threaded flanges, while those above 4 kg of pressure should use焊接 flanges. Place a sealing gasket between the two flange plates and then securely tighten with bolts. Flanges of different pressure ratings have varying thicknesses and require different bolts.
