The blind flange is so named due to the lack of a bore: it is a solid flange. It is used to close off the ends of piping systems and pressure vessel openings. As such it can be used in an existing operation flow, or for future expansion requirements. It also permits easy access to the interior of a line or vessel once it has been sealed and must be reopened.
These pipe flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel. Blind pipe flanges also allow for easy access to the pipe in case work must be done inside the line. They are oftentimes used for high pressure applications.
