What is flange contain cover size for ANSI flange

ANSI Flange Sizes and Pressure Classes:

1. Flange Size Range (Nominal Diameter):

   • DN 15 (1/2 inch) to DN 600 (24 inches) are typical sizes for ANSI flanges.
   • Flanges are typically labeled by nominal size (in inches or millimeters), which corresponds to the bore diameter of the flange.

2. Pressure Classes:

   • ANSI 150: Typically for lower pressure applications.
   • ANSI 300: For medium pressure applications.
   • ANSI 600: For higher pressure applications.
   • ANSI 1500 and ANSI 2500: For very high-pressure applications.
