Non-standard Flange

Flange, also known as a flanged disc or rim, is a component used for connecting shafts or for joining pipe ends; it's also used on equipment进出口 for inter-device connections, such as reducer flanges. A flange connection or flange joint refers to a detachable joint made up of a flange, a gasket, and bolts, working together as a sealing assembly. Pipe flanges are flanges used for piping in pipeline installations; when used on equipment, they refer to the equipment's进出口 flanges. Flanges have holes, and bolts are used to tightly secure the two flanges. Seals are placed between the flanges for密封. Flanges come in threaded (screwed) connections,焊接 connections, and clamp connections. Flanges are used in pairs; low-pressure piping can use threaded flanges, while pressures over four kilograms require焊接 connections. Two flange discs are fitted with a sealing pad and then fastened with bolts. Flanges of different pressures have varying thicknesses and require different bolts. In pumps and valves, the parts that connect to pipes are also made into corresponding flange shapes, known as flange connections. Any connection piece that uses bolts to join two flat surfaces while also sealing is generally called a "flange," such as the connections in ventilation pipes. These types of components can be referred to as "flange-type parts." 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 a "flange-type part." Smaller components like valves can be referred to as "flange-type parts."
