Calculate Steel Pipe
Weight
Steel Pipe Weight in Pounds/ Foot
Pipe Weight = 10.6802 X (D  T) X T
Where
D = outside diameter (inches),
T = pipe wall thickness (Inches)
Steel Pipe Weight in Kg/ Meter
If thickness is in mm
Pipe Weight = 0.02464
X (D  T) X T
If
thickness is in cm,
Pipe Weight = 2.464
X (D  T) X T
If thickness is in inches
Pipe Weight = 15.89
X (D  T) X T
