[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure.

[0003] When the existing flange is in use, it is directly fixed on both ends of the transport pipeline. When connecting two pipelines through the flange, the operator needs to constantly adjust the position of the pipeline in order to make the two flange threaded holes face each other. Since the pipeline is heavy, the operator's work intensity is high and the work efficiency is low. In addition, the method of connecting the two flanges by bolts is also relatively complicated and not convenient enough, which affects the connection efficiency and speed of the pipeline and the flange.
