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
A Raised Face Blind Flange features a slightly elevated surface around the sealing area, which enhances gasket compression and ensures a tighter, more reliable seal. It is commonly used in high-pressure piping systems to isolate sections during maintenance or inspection. The raised face design improves leak prevention in applications involving steam, gas, and chemical flow.
Flat Face Blind Flange Flat Face Blind Flange
Flat Face Blind Flanges are designed with a smooth, uniform sealing surface that allows for full contact with the mating flange or gasket. This type is ideal for low-pressure systems where flange surface distortion must be avoided, such as in water distribution and low-temperature piping. Its even face ensures consistent sealing without the need for extra reinforcement.
