ASME B16.47 Flanges

What Are ASME B16.47 Flanges?

ASME B16.47 flanges are specifically engineered for pipes with a nominal size of 26 inches to 60 inches. These flanges are available in two series: Series A and Series B. While Series A flanges are thicker and heavier, making them suitable for higher-pressure applications, Series B flanges are lighter and designed for systems with lower pressure requirements. Both series ensure secure and leak-proof connections in industrial piping systems.

What Are ASME B16.9 Flanges?
