Sliding Flange

Flange, also known as a flange disk or raised rim. A flange is a component that connects two shafts and is used for joining pipe ends; there are also flanges used at equipment inlets and outlets for connecting two devices, such as a reducer flange. Flange connection or flange joint refers to a removable connection formed by the combination of flange, gasket, and bolt. Pipe flanges are the flanges used in piping installations; on equipment, they refer to the equipment's inlet and outlet flanges. Flanges have holes, and bolts secure them tightly together. Gaskets are used to seal between flanges. 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 require焊接 flanges. A sealing gasket is placed between the two flange disks, and then bolts are used to tighten them. Flanges of different pressures have different thicknesses, and they require different bolts. In the case of pumps and valves, when connected to pipes, these equipment components are also shaped like corresponding flanges and are called flange connections. Any connection piece that uses bolts to join two flat surfaces around the perimeter and is sealed is generally called a "flange," such as the connection of ventilation pipes. These types of components can be referred to as "flange-type parts." However, such a connection is only a part of a single device, like 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."
