Flange, also known as Flange Flange Flange plate or Flange. Flange is the shaft and shaft connected to each other parts, used for the connection between the pipe end; there are also used in the equipment import and Export Flange, used for the connection between the two equipment, such as reducer flange. Flange connection or flange joint refers to the Flange, gasket and bolts are connected with each other as a group of combination of sealing structure of the detachable connection. Pipeline flanges refer to flanges for piping installation and for equipment, refer to import and export flanges for equipment. There are holes in the Flange, and the bolts make the two flanges close together. Gasketed sealing between flanges. Flange is divided into thread connection (screw thread connection) Flange, welding flange and clamp flange. Flanges are used in pairs, low-pressure pipe can use wire flange, more than four kilograms of pressure to use welding flange. Add a gasket between the two flanges and then tighten with bolts.
Different pressure flange thickness, they use bolts are different. Pumps and valves, in connection with the pipeline, these equipment parts, also made into the corresponding flange shape, also known as flange connection. Generally in the two plane around the use of bolt connection at the same time closed connection parts, generally known as "Flange" , such as ventilation pipe connection, this type of parts can be called "flange-type parts. But this connection is only a part of the equipment, such as Flange and pump connection, it is not good to the pump called "flange parts. ". Relatively small, such as valves, can be called "flange parts. ".
