Frequently Asked Questions

What is an ANSI flange?+

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.

What pressure classes do ANSI flanges come in?+

ANSI flanges are manufactured in Class 150, 300, 400, 600, 900, 1500, and 2500 pressure ratings, each designed for specific pressure-temperature service conditions.

How do ANSI flanges differ from DIN flanges?+

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.
