Flange masses (weights) according to standard EN 1092-1

Flange masses (weights) as defined by EN 1092-1 vary depending on the type of flange, nominal diameter (DN), pressure rating (PN), and material. The weight of a flange is influenced by factors such as its thickness, outer diameter, bolt circle, and raised face height. Typically, flanges with higher pressure ratings (e.g., PN100) will have more material and greater mass compared to lower-rated flanges (e.g., PN10 or PN16). For example, a PN10 flange will generally have a lighter mass due to its thinner body and lower pressure capacity, whereas a PN100 flange will be much heavier because it is designed to withstand higher pressures and requires thicker walls and reinforced construction. Material choices (such as carbon steel, stainless steel, or alloy steel) also influence the overall weight.
