A Flange (Flange), also known as a Flange collar or Flange. The flange is a part for connecting pipes and is used for connecting pipe ends; there are also flanges on the inlet and outlet of the equipment for the connection between two pieces of equipment, such as reducer flanges. The flange connection or flange joint is a detachable connection which is formed by connecting a flange, a gasket and a bolt together to form a combined sealing structure. The pipeline flange is a flange for piping in a pipeline device, and is used on equipment to be an inlet and outlet flange of the equipment. The flanges are provided with holes, and the two flanges are tightly connected through bolts. The flanges are sealed with a gasket. The flange is divided into a threaded connection (screw thread connection) flange, a welding flange and a clamping flange.
