Flanges, also known as raised face plates or flanged discs, are components used for connecting shafts to shafts, typically for joining pipe ends; they are also used at equipment inlets and outlets, such as reducer flanges. A flange connection or flange joint refers to a removable connection consisting of a flange, a gasket, and bolts, forming a combination seal structure. Pipe flanges are the flanges used in piping installations; when used on equipment, they refer to the equipment's inlet and outlet flanges. Flanges have holes, and bolts are used to tightly secure the two flanges together. They are sealed using a gasket. Flanges come in threaded (screwed) connections,焊接 (welded) flanges, and clamp flanges. Flanges are always used in pairs; low-pressure pipelines can use threaded flanges, while those above 4 kg of pressure use焊接 flanges. Two flange discs are joined with a sealing pad and then bolted together. Flanges of different pressures have different thicknesses and require different bolts. When pumps and valves are connected to pipelines, the local parts of these equipment items are also made into corresponding flange shapes, also known as flange connections. Any connection piece that uses bolts to connect two flat surfaces and is sealed simultaneously is generally called a "flange," such as the connection of ventilation pipes. Such components can be referred to as "flange-type parts." However, this type of connection is only a part of a single piece of equipment, such as the connection between a flange and a pump, so it's not appropriate to call the pump a "flange-type part." Smaller items like valves can be called "flange-type parts."

Flange connections involve securing two pipes, fittings, or equipment to separate flange plates first, then adding a flange gasket between them and tightening them together with bolts, thereby completing the connection. Some fittings and equipment come with flange plates as standard, which also fall under flange connections. Flange connections are a crucial method in pipeline construction. They are convenient to use and can withstand high pressures. In industrial pipelines and residential settings, where pipe diameters are small and pressure is low, flange connections are not visible. However, in boiler rooms or production sites, flange connections are everywhere, visible on pipelines and equipment.
