ASME B16.5 blind flange also called as block flange without center hole is used to close the end of pipes. The function of blind flange is similar to welding head and threaded pipe cap. Blind flange and threaded pipe cap can be disassembled at any time. Blind flange has various types of flanging face, including full face (FF), raised face (RF), male and female face (MF), tongue and groove face (TG), ring joint face (RTJ).
