What is a flange connection system?


Flanges are the parts that connect the shaft to the shaft and are used for the connection between the pipe ends. They are also used for flanges on the equipment inlet and outlet, for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to the detachable connection of flanges, gaskets and bolts as a set of combined sealing structures. Pipeline flange refers to the flange used for the piping in the pipeline device. It is used on the equipment to refer to the import and export flange of the equipment. There are holes in the flange, and bolts make the two flanges tight.

The flanges are sealed with a gasket. The flange is divided into threaded connection (thread connection) flange, welding flange and clip flange. Flanges are used in pairs. Low-pressure piping can use wire-flanged flanges. Welding flanges with a pressure of more than four kilograms are used. Seals are added between the two flanges and then bolted. Different pressure flanges have different thicknesses and they use different bolts. Pumps and valves, when connected to pipes, are also made in the form of corresponding flanges, also called flanged connections.

All connected parts that are bolted together and sealed at the periphery of two planes are generally called “flanges”, such as the connection of ventilation ducts. This type of part can be called a “flange type part”. However, this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not easy to call the pump "flange parts." Smaller valves, such as valves, can be called "flange parts." [1]
