A Flange Blind Plate is a solid disc with bolt holes and no central opening, used to permanently or temporarily seal the end of a pipe or a flange connection. Also called a blind flange or flange cover, this Flange Blind Plate provides a secure, leak-proof closure that can be installed or removed as needed for maintenance, system testing, or to cap unused nozzles. It functions similarly to a pipe cap but is designed for bolted, reversible installation between standard flanges
