The BL Type Flange, commonly known as a Blind Flange, is a solid flange without a center bore used to seal the end of a piping system, valve, or pressure vessel opening. Unlike other flanges that connect two pipe sections, a blind flange provides a secure closure and leak-proof seal, effectively terminating the pipeline where flow isn’t required. This design also allows easy access for inspection, maintenance, or future system expansion when bolted to a mating flange with a gasket. BL Type flanges are suitable for applications across industries such as oil & gas, petrochemical, water treatment, and power generation, and are available in various materials including carbon steel and stainless steel with different face types like raised face (RF), flat face (FF), and ring type joint (RTJ) to match the sealing needs of your piping system.
