316L Flange

Flange, also known as a flange disc or boss, is a component used for inter-axial connections, typically for pipe end connections; it is also used at equipment inlets and outlets, such as reducer flanges. A flange connection or flange joint refers to a detachable connection formed by the combination of flanges, gaskets, and bolts as a sealing assembly. Pipe flanges are flanges used for piping in pipe installations; on equipment, they refer to the equipment's inlet and outlet flanges. Flanges have holes, and bolts secure the two flanges together. Gaskets are used to seal between flanges. Flanges come in threaded (screwed) connections,焊接 (welded) flanges, and clamp flanges. Flanges are used in pairs; low-pressure pipelines can use threaded flanges, while those above 4 kg pressure require焊接 flanges. A sealing gasket is placed between the two flange discs, and then bolts are tightened. Flange thickness varies with pressure, as do the bolts used. In the case of pumps and valves, when connected to pipes, these equipment components are also made in corresponding flange shapes, known as flange joints. Any connection piece used to connect two flat surfaces around the edge with bolts and simultaneously seal is generally called a "flange," such as in the case of ventilation pipe connections, which can be referred to as "flange-type components." However, such connections are only a part of a device, like the connection between a flange and a pump, so it's not appropriate to call the pump "flange-type components." Smaller components like valves can be called "flange-type components."
