ANSI / ASME Flange Pressure Ratings: Class 150 to 2500
ASME B16.5 and ASME B16.47 standards define standardized pressure–temperature limits for flanged piping systems. Each of those pressure classes corresponds to a specific pressure–temperature rating, which varies by material group and operating temperature. This article explains ANSI / ASME pressure ratings from Class 150 through Class 2500, outlines the key differences between ASME B16.5 and […]
