Alloy steel and carbon steel blind flanges are solid, plate-like flanges used to close the end of a pipe, valve, or equipment nozzle. They provide a safe, strong termination point for piping systems where flow needs to be stopped or access needs to be provided for inspection and maintenance. Blind flanges are common in oil & gas, petrochemical, power plants, refineries, and other industrial pipelines.
