Introduction to Blind Flanges
A blind flange is a type of flange used to seal the end of a pipe, valve, or vessel. It is a solid disk with bolt holes around the perimeter, which allows it to be bolted onto the mating flange. Blind flanges are crucial in piping systems as they prevent the flow of fluids or gases and provide easy access for inspection, cleaning, or maintenance of the system. They are widely used in various industries such as oil and gas, petrochemical, power generation, and water treatment.
