[0002] A flange, also known as a flange plate or a flange, is a part used to connect pipes to each other. It is connected to the pipe end. There are holes on the flange, and bolts are used to tightly connect the two flanges. A gasket is used for sealing between the flanges. A flange is a disc-shaped part and is the most common in pipeline engineering. Flanges are always used in pairs. In pipeline engineering, flanges are mainly used for pipeline connection. At the ends of two pipelines that need to be connected, a flange plate is installed on each end. For low-pressure pipelines, threaded flanges can be used. A sealing gasket is added between the two flange plates, and then bolts are used to fasten the water pump and the valve. When connecting with the pipeline, the corresponding flange shapes are also made at the local parts of these equipment and devices, which is also called flange connection. Flange forging is divided into internal flange forging and external flange forging. Among them, the external flange forging is used for connection and fixation between various devices. The flange forging connection is convenient to use and can withstand a large pressure.
