Flanges are interconnected parts of pipes and pipes for connection between pipe ends. Flanges are also used at the inlet and outlet of the equipment for connection between two devices, such as reducer flanges. Flange connection or flanged joint, refers to the flange, gaskets and bolts are interconnected as a group of a combination of sealing structure detachable connection. Pipe flanges are flanges used in piping for piping purposes and are used in equipment to refer to the inlet and outlet flanges of equipment. There are holes in the flange, the two bolts so tightly connected flange. Between the flange gasket seal. Flange threaded connection (threaded connection) Flange, welding flange and clamp flange. Flanges are used in pairs, low-pressure pipe can be used to connect the flange, more than four kilograms of pressure welding flange. Between the two flanges with a gasket, and then bolted. Different thickness of the flange pressure, they use different bolts. Pumps and valves, and pipe connections, these equipment, local equipment, but also made into the corresponding flange shape, also known as the flange connection. Where in the two plane around the use of bolts connected simultaneously closed parts, generally referred to as "flange", such as ventilation pipe connection, this type of part can be called "flange parts." But this connection is only a part of the device, such as the flange and the pump connection, it is not good to call the pump "flange parts." Relatively small, such as valves, etc., can be called "flange parts."

Reducer flange for the connection of the motor to the gear unit and the connection between the gear unit and other equipment.
