Stiffness requirements for carbon steel flange, flange design, strength calculation, only the few stiffness calculation, but more and more of the production practice has proved that may also affect the flange sealing flange stiffness, less rigid flange buckling deformation will produce too much, make the gasket stress is not uniform, and cause leakage. Carbon steel flange connection is a detachable connection. According to the connection of parts can be divided into the vessel flange and pipe carbon steel flange. In high voltage equipment and pipelines, using 10 copper, aluminum, steel, stainless steel type lens or other shaped metal gasket. High pressure washers and sealing surface contact width is very narrow (line contact), the sealing surface with gasket processing carbon steel flange finish higher.
