Stainless Steel Blind Flanges are mostly used to seal the end or opening of a pipe, through which they come without a bore. This comes in handy for inspection and pressure tests, as it allows quick access to the pipe. It is used to terminate the end of a piping system. The blind flange is a flange that does not have a hub or a boring centre. Blind flanges have the face thickness of a flange, a matching face type, and a similar bolting pattern. Stainless Steel Blind Flanges can also be used to seal a nozzle opening on a pressure vessel.
