Marine flange is used in ships on the flange, the flange is to make the pipe and pipe connected parts. For the flat welding flange can be divided into flat welding neck flange and plate lap welding flange two kinds. Flat welding flange has the advantage of simple manufacture, low production cost, but not resistant to high temperature and high pressure, mainly for the line of pressure below 2.5 MPa at room temperature, is using most of the flange of the ship.

Selection of pressure vessel flange rating shall be not less than the flange material under the design temperature allows working pressure. The vacuum system of pressure vessel flange level generally should not be less than 0.6 MPa. When the operation for easy was, explosive or toxic medium should be used as high a level of flange.
