Blind flange have same similar function as plug or cap, all of them are used to block off a section of piping system. It is different as the others flanges, there is no hub and bore in the center.
Forged steel flange is a disc-shaped piece of equipment used to connect a pipe to fittings or valve or other component to form a pipework system. Usually flange has been attached to pipe or tube end to, and then a gasket is inserted in the middle to form a seal. Finally they are joined together with bolts and nuts.
ASME B16.5 Standard
This standard covers pressure temperature ratings, materials, dimensions, tolerances, marking, testing and methods of designating openings for pipe flanges and flanged fittings. Such as weld neck flanges, slip-on flanges, socket weld flanges, threaded flanges, blind flanges, lap joint flanges and flangolets.
