A Blind Flange (BLF) is a type of pipe flange used to close the end of a piping system, valve, or pressure vessel opening. It has no bore (no hole) in the center, making it ideal for fully blocking flow or sealing off a section of a pipeline.

Blind flanges deliver strong sealing performance, especially for high-pressure and high-temperature systems. They can also be removed and reinstalled, allowing easy access for maintenance, inspection, or future pipeline extensions.
