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

on . Posted in Pipe

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

 

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

\( W =  10.68 \; (D - t) \; t  \)     (pipe and round tubing)

\( W =  13.60 \; [\; (l + w) - t \;] \; t \)     (rectangular tube)

\( W =  13.60 \; (D - t) \; t  \)     (square tube)

\( W =  0.2836 \; t \; 144  \)     (plate)

\( W =  0.2225 \; d^2 \; t  \)     (plate circle) 

\( W =  0.2904 \; t \; 144  \)     (sheet)

\( W =  3.403 \; t \; w  \)     (flat bar) 

\( W =  2.945 \; d^2  \)     (hexagon bar) 

\( W =  2.817 \; d^2  \)     (octagon bar) 

\( W =  2.673 \; d^2  \)     (round bar)

\( W =  3.403 \; d^2  \)     (square bar)

\( W \) = pipe weight per foot (approximate) \( lbf \)  -
\( d \) = diameter \( in \) -
\( l \) = length (long side) \( in \) -
\( D \) = pipe outside diameter \( in \) -
\( t \) = pipe thickness \( in \) -
\( w \) = width (short side) \( in \) -
