The calculator weight is used to choose the package and transportation method, beause Lap joint stub end is usually in small demands. It is generally a section of the lap joint flange.The stainless steel stub end is matched with the galvanized carbon steel lap joint flange for saving cost. There are 3 types.
l Type A is employed for standard joint flange
l Type B is employed for standard slip on flanges as lap flanges.
l Type C will be used for standard lap joint flange, and put on flange.
Option 1
The weight can be found from the below chart. It is common and widely used thickness schedule in the pipeline system.

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
