(Summary description)Grooved pipe fittings flange is also called flange flange disc or flange. The flange is a part connected between the pipe and the pipe, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. Pipe flange refers to the flange of the pipe distribution pipe in the pipeline device, used in the equipment refers to the import and export flange of the equipment. A hole bolt is arranged on the flange of the grooved pipe fitting to make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (thread connection) flanges, welded flanges and clamp flanges. Flanges are used in pairs, wire flanges can be used for low pressure pipes, and welded flanges for more than four kilograms of pressure. Put a gasket between the two flanges and fasten them with bolts. Different pressure flange thickness is different, they use different bolts. Pumps and valves, when connected with pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All the connecting parts that are connected by bolts around two planes and are closed at the same time are generally called "groove pipe flange", such as the connection of ventilation pipes, this type of part can be called "flange class parts". But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to call the pump "flange parts". Relatively small such as valves, etc., can be called "flange parts".
