Abstract
The flange is defined in a similar disc shaped metal body peripheral opening several fixing holes for connection to a part of something else. Mainly used to make the pipes are connected to each other, connected to the tube end. The flange plate with holes, can be worn bolt, make the two flange connect. The flange gasket seal. It can be formed by casting, also can be connected by threads or welding. Flange connected by a flange, a gasket and a nut composed of a number of bolts, the sealing surface of the flange gasket is placed in between, fastening nut, the gasket on the surface pressure reaches a certain value after the deformation, and filled with dense cover on the uneven, so closely linked traps. Flange connection is convenient to use, can withstand greater pressure, pipeline construction an important connection.
