Flange, also known as flange flange or flange. The flange is the interconnected part between the pipe and the pipe for the connection between the pipe ends; it is also used for the flange on the inlet and outlet of the equipment for the connection between two equipment, such as the reducer flange. A flange connection or a flange joint refers to a detachable connection in which a flange, a gasket and a bolt are connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in the pipeline installation. It is used on the equipment to refer to the inlet and outlet flanges of the equipment. There are holes in the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flange threaded connection (threaded connection) flange, welded flange and clip flange. Flanges are used in pairs. Low-pressure pipes can be used with wire-bonded flanges. Weld flanges are used for pressures above four kilograms. A gasket is placed between the two flanges and then bolted. Different flange thicknesses for different pressures use different bolts. Pumps and valves, when connected to the pipeline, part of these equipment, also made into the corresponding flange shape, also known as flange connection. Connection parts that are bolted at the same time around two planes are generally referred to as "flanges". For example, the connection of ventilation ducts may be referred to as "flange parts". However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the pump "flange parts". Smaller ones such as valves 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.
