AISI 304 304L 8inch Class150 Stainless Steel Flat Face Blind Flange
►Product Description
A blind flange, also known as a flange cover, blind disk, or flanged pipe plug, is a solid disk without a central hole used to seal pipe openings. Its primary function is similar to that of a pipe plug or cap, but it is designed as a detachable component, making it easier to replace or maintain. By bolting it to the end of a pipe, it effectively blocks the flow of fluids or gases, providing a secure and removable closure solution.
