Option 2

Stub End Callucation Formula

You can also get the weight by calculation formula / calculator.

W=0.0251352 x 0.001 x [t x ({G²-OD²}/4+(F x t x (OD-t)]



Where:

W = Weight of lap joint stub end in kg.

OD = Outside diameter of barrel (mm) same as pipe

T= Wall Thickness(mm) same as pipe

F = Length of barrel (mm) from below chart

G = Diameter of Lap (mm) from below chart
