The weight chart for blind flanges above gives an estimate of the weights of ASME B16.5 Class 150 raised face blind flanges for a range of nominal pipe sizes, from ½" to 24". Larger outside diameters and the need for thickness to resist pressure conditions cause the weight to gradually grow with size. Planning, estimating, transportation, and structural load calculations all use these values as a general guide. Depending on the material grade (carbon, stainless, alloy, or duplex steel), as well as certain production tolerances and pressure ratings, actual weights may differ slightly.
Type of Sub-products
Raised Face Blind Flange Raised Face Blind Flange
Ensures tight sealing in high-pressure piping systems by providing a smooth raised surface.
Flat Face Blind Flange Flat Face Blind Flange
Ideal for low-pressure applications where a uniform contact surface is required for gasket sealing.
