Girth flanges are used for mating two segments of a pressure vessel. These parts are also widely used in shell and tube heat exchangers and other process equipment to mate various components. There are two common kinds of girth flange such as welded hub jointloose type (without hub). Depended to design of equipment girth flange may has raised face gasket seating area. The seating area can be special surface finished which is suitable for better sealing and prevent leakage.

 

 

For pressure vessels, a flange is a component, which includes flanges, gaskets, connecting bolts or studs, and nuts. Its function is to combine different pressure-bearing components while ensuring that the connection parts do not leak.
