Introduction to Blind Flange
A blind flange is a type of flange used to close 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 commonly used in various industries such as oil and gas, chemical, power generation, and water treatment. They serve several important functions, including providing a seal to prevent leakage, allowing for easy access to the interior of the pipe or vessel for inspection and maintenance, and providing a connection point for future expansion or modification.
