A blind flange is a flange used to seal off a part of a pipe system or a vessel's opening. It is intended to shut the end of a pipe or vessel temporarily or permanently. Blind flanges are normally solid discs with bolt holes around the circumference for connecting to other flanges or equipment.
These flanges are widely employed in piping systems for maintenance, inspections, or to isolate a segment of the pipeline from the rest of the system. They seal the open end of the pipe or vessel, preventing fluid or gas from flowing through it.
Blind flanges come in a variety of diameters, materials, and pressure ratings to fit varied applications and operating circumstances in industries such as oil & gas, petrochemicals, chemical processing, and power generation.
