A blind flange is a popular type of pipe flange. It has no bore in the center,and is primarily used to close the ends of piping systems.This flange premits easy access to a line once it has been sealed.It sometimes can be machined to accept a nominal sizes pipe to which a threaded or welded reduction is being made. Yaang blind flanges are available in various sizes and material for you to choose from.
