A weight calculating formula for steel pipes

If the outside diameter and the wall thickness of a steel pipe is known, the weight per foot can be expressed as:

m = 10.68 (d_o - t_w) t_w (1)

where

m = weight per foot (lbs/ft)

d_o = outside diameter (inches)

t_w = wall thickness (inches)

Example - Weight of 4" Schedule 40 Steel Pipe

The outside diameter (d_o) of 4" Schedule 40 Steel Pipe is 4.500 inches. The wall thickness is 0.237 inches. The weight per foot can be calculated using (1) as:

m = 10.68 (4.500 - 0.237) 0.237

= 10.79 lbs/ft
