Blind Flange is a bore-less pipeline flange welded to end of the pipe in order to terminate the pipeline.
Blind Flange is used to terminate the pipeline. It is bolted together with a mating flange with corresponding flange facing with a sealing gasket to provide effective leak proof joint.
blind Flange is a flange which has no bore, and is used to close ends of piping systems. A blind flange also permits easy access to a line once it has been sealed. The blind flanges are sometimes machined to accept a pipe of the nominal Size to which reduction is being made. The reduction can be either threaded or welded.
