What is a Stainless Steel Blind Flange?
A Blind Flange is a solid, circular plate used to seal the end of a pipe, valve, or pressure vessel. Unlike other flanges, it has no bore (opening), effectively blocking the flow of fluids or gases in a pipeline.
Made from high-grade stainless steel such as SS 304, SS 316, SS 321, SS 347, SS 310, and SS 904L, blind flanges provide high strength, corrosion resistance, and leak-proof sealing for high-pressure and high-temperature applications.
