The application of flange
The flange is used for positioning. For example, there is an installation method for oil cylinders, which is called flange installation. For example, four symmetrical holes are punched around a cuboid, and there is a large hole in the middle, which is the same as the outer diameter of the oil cylinder. Put this cuboid on the oil cylinder, and they can be welded and fixed together in other ways. The connection between the oil cylinder and other things is connected by the four holes around the cuboid, and this cuboid can be called a flange.
