Blind Flange

A Blind Flange is a type of pipe flange that is used to close the end of a pipe system or pressure vessel opening. It is commonly used for maintenance purposes or to block off a section of piping that is no longer in use. The blind flange is typically bolted onto the end of a pipe or fitting with bolts, and it does not have a bore or an inside diameter, hence the term “blind.” This means that it effectively seals the end of the pipe or vessel, preventing the flow of fluids or gases. Blind flanges are available in various sizes, materials, and pressure ratings to suit different applications and operating conditions.
