“A flange is a forged or cast ring of steel designed to connect mechanical sections of pipe or join pipe to a pressure vessel, pump, valve or any other piece of equipment.”
Usually flanges are welded or threaded, and two flanges are joined to each other by bolting together them with gaskets to provide a seal. It provides an easy access to the piping system in case of cleaning, modification, and inspections.
