Girth flanges
Girth Flange can be made in carbon steel,low temperature steel,alloy steel,stainless steel etc.We are a professional manufacturer of Girth Flanges in China.
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.
Material
The strict use of high quality raw material is guaranteed and proved by raw material certificate with each delivery. Material range is varied from ordinary carbon steel to alloy steel, all grades of Stainless Steel, non-ferrous (Brass, Al-Brass, Copper Nickel) and wide range of Clad Steel consisting of corrosion resistant materials.
