What is carbon steel blind flange?

Blind flanges are used to seal the ends of piping systems. It is a round plate with no central fixation but with all the appropriate bolt holes. Available in a variety of sizes and materials, blind flanges are used to provide a reliable closure at the end of a pipe, valve or equipment nozzle. When sealed, the flange facilitates easy access to the line. Blind flanges are sometimes custom made or machined to accept pipes of reduced nominal size.
