We supply flanges for data center cooling systems, fire suppression piping, and critical infrastructure. Hyperscale facilities require precision-manufactured flanges that meet demanding specifications for reliability and performance.
A blind flange seals the end of a piping system, vessel nozzle, or valve. It is a solid disk with bolt holes around the perimeter that bolts to a mating flange to create a pressure-tight seal.
Blind flange thickness depends on design pressure, temperature, material allowable stress, and diameter. ASME B16.5 provides standard thicknesses for each size and pressure class combination.
Yes, blind flanges are commonly installed where future piping connections are anticipated. They can later be removed and replaced with a pipe flange without cutting into the system.
