What is the maximum flange size covered by B16.5?

Explanation:
B16.5 defines pipe flanges and their dimensions, bolt patterns, and pressure-temperature ratings, and its scope includes flanges from 1/2 inch up to 24 inches (NPS). So the largest flange size covered by this standard is 24 inches. For larger diameters, 26 inches and up, a different standard (B16.47) applies.
