Approximate weight of a Lap Joint Stub End as per ASME B16.9 can be calculated as per following formula  :

    \[W=0.0251352 \times 0.001\times[t\times(\frac{G^2-OD^2}{4})+({F}\times{t}\times(OD-t))]\]

Where :

  1. W = Weight of Lap Joint Stub End in Kg.
  2. OD = Outside diameter of barrel (mm)
  3. F = Length of barrel (mm)
  4. t = Wall Thickness (mm)
  5. G = Diameter of Lap(mm)
