Girth Flange & Ring
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 joint, loose 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.
