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.
ANSI flanges conform to dimensional and pressure-temperature standards set by the American National Standards Institute, primarily ASME B16.5 for sizes NPS 1/2 through 24 and B16.47 for sizes NPS 26 through 60.
ANSI flanges are manufactured in Class 150, 300, 400, 600, 900, 1500, and 2500 pressure ratings, each designed for specific pressure-temperature service conditions.
ANSI flanges follow American dimensional standards with imperial bolt patterns, while DIN flanges follow European metric standards. The two systems are not interchangeable without adapters.
