What Are Blind Flanges?

Blind Flanges, also known as BLRF (Blind Raised Face Flanges), are solid disks used to block off the ends of piping systems. Unlike other flange types, they have no bore and are commonly used for pressure testing, maintenance, or sealing a piping line that is not in use. These flanges allow easy access for inspection or flow redirection and are essential in systems where disconnection or pressure isolation is needed.
