A blind flange, sometimes called a flange cover, blind disc, or flanged pipe plug, is a solid piece with no hole in the center. It’s designed to seal off the end of a pipe or pressure vessel. Think of it like a cap or plug, but with the added benefit of being bolted in place — which means it can be easily removed when needed for maintenance, inspections, or system changes.
When installed at the end of a pipeline, a blind flange creates a strong, leak-proof seal that keeps fluids or gases from escaping under pressure. Its sturdy design and ability to be reused make it especially useful in situations where you need a secure shut-off but still want the option to access or reopen that part of the system later.
