The flanged water finger is actually a fire-fighting appliance. So, do you know what the flange is? It is actually a disc-shaped part, which is more common in pipeline engineering, and the flanges are used in pairs. Multistage pumps In pipeline engineering, pipeline pump flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed. The low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A sealing point is added between the two flanges and then fastened with bolts. Different pressure flanges have different thicknesses and use different bolts. Gear oil pump pumps and valves, when connected to the pipeline, the parts of these equipment are also made into the corresponding flange shape, also known as flange connection. Connection parts that are closed at the same time by bolting on both 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". Oil drum pumps are relatively small, such as valves, and can be called "flange parts." This is an introduction to the flange. Through this article we can also see that fire-fighting appliances and pumps are inseparable, so they must be used together!
