Flanges typically refer to a disk-like metal component with several holes drilled around its periphery for fastening and connecting to other components. This product is a mechanical part used to connect shafts to each other or to join pipe ends. Flanges are also employed at the inlet and outlet ports of equipment for connecting two units. By using bolts, a gasket at the sealing surface can be tightened to ensure a secure, leak-proof connection. Flanges are widely used in fields such as power generation, petroleum refining, chemical processing, offshore engineering, and shipbuilding.
