2. Size Range: The dimensions specified by ANSI B16.5 cover flanges ranging from 1/2 inch to 24 inches in nominal pipe size.
3. Pressure Classes: The standard includes flanges in pressure classes ranging from 150 to 2500.
4. Materials: Materials: Only flanges and flanged fittings constructed of cast or forged metal are covered by ANSI B16.5.
5. Types of Flanges: ANSI B16.5 covers various types of flanges, including weld neck, slip-on, socket weld, threaded, lap joint, and blind flanges.
6. Blind Flange Dimensions: The technical drawing and dimensions for Class 150 blind flanges (NPS 1/2 to NPS 24) are specified by the standard
