Weight for Steel Bars, Pipe, and Tubing (lb)

Written by Jerry Ratzlaff on . Posted in Pipe

These formulas calculate the weight per foot for various pipe and structural shapes.

 

Formulas that use Weight for Steel Bars, Pipe, and Tubing (lb)

\(\large{ W =  10.68 \; (D - t) \; t  }\) (pipe and round tubing)
\(\large{ W =  13.60 \; [ (l + w) - t ] \; t }\) (rectangular tube)
\(\large{ W =  13.60 \; (D - t) \; t  }\) (square tube)
\(\large{ W =  0.2836 \; t \; 144  }\) (plate)
\(\large{ W =  0.2225 \; d^2 \; t  }\)   (plate circle) 
\(\large{ W =  0.2904 \; t \; 144  }\) (sheet)
\(\large{ W =  3.403 \; t \; w  }\)  (flat bar) 
\(\large{ W =  2.945 \; d^2  }\)  (hexagon bar) 
\(\large{ W =  2.817 \; d^2  }\)  (octagon bar) 
\(\large{ W =  2.673 \; d^2  }\) (round bar)
\(\large{ W =  3.403 \; d^2  }\) (square bar)

Where:

\(\large{ W }\) = pipe weight per foot (approximate)

\(\large{ d }\) = diameter

\(\large{ l }\) = length (long side)

\(\large{ D }\) = pipe outside diameter

\(\large{ t }\) = pipe thickness

\(\large{ w }\) = width (short side)
