What Are Blind Flanges?

Blind Flanges are solid disk-shaped components used to seal the end of a piping system or vessel opening. Unlike other flanges, they have no center bore, making them perfect for pressure isolation, maintenance access, and line testing. Also referred to as BLRF (Blind Raised Face) Flanges, these components are essential in systems that require secure closure and future access.
