Forged Blind Flange
A blind flange (also called a ‘closure plate flange’) is installed at the end of a piping system to terminate a pipe. It has no centre hole (bore), so there is no flow through the flange. A blind flange may be used for isolating a pipe, valve, or pressure vessel. This type of flange is available in all sizes and classes, and may use a flat, raised, or ring-type joint face
