►Product Description
A blind flange, also referred to as a flange cover, blind disk, or flanged pipe plug, is a solid disk without a center hole, primarily used to seal pipe openings. Its function resembles that of a pipe plug or cap, but it is designed as a detachable component, simplifying replacement and maintenance. When bolted to the end of a pipe, it effectively prevents the flow of fluids or gases, providing a secure yet removable sealing solution. This design combines practicality and ease of use, making it a reliable and convenient option for pipeline systems requiring accessible and dependable closures.
