The weight table for ASME B16.5 Class 150 raised face blind flanges covers nominal pipe sizes from ½" to 24". The weight gradually increases with growth due to greater exterior diameters and thickness requirements to resist pressure conditions. These values are used as a general reference for planning, estimate, transportation, and structural load calculations. Actual weights may differ significantly based on the material grade (carbon steel, stainless steel, alloy steel, or duplex steel), as well as specific manufacturing tolerances and pressure ratings.
