A blind flange is a solid disc drilled to the same bolt pattern as the flange it closes. It blanks off the end of a line, a spare tee branch or a vessel nozzle, and can be removed later to extend the system. A blind flange carries the full line pressure across its face, so for the same class it is thicker than most other flange types. It is also the standard closure for hydrostatic tests.
Hamza Fasteners stocks MS blind flanges from 1/2 inch to 12 inch in ASME B16.5 Class 150 and Class 300, raised or flat face, plus PN16 drilling. Blinds can be supplied drilled and tapped for a vent, drain or pressure gauge. Contractors in Dubai use them on fire mains, chilled water and process lines. Send your list for a fast price.
