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.

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

(Eq. 1)  \(\large{ W =  10.68 \; (OD - t) \; t  }\)     (pipe and round tubing)

(Eq. 2)  \(\large{ W =  13.60 \; [ (l + w) - t ] \; t }\)     (rectangular tube)

(Eq. 3)  \(\large{ W =  13.60 \; (OD - t) \; t  }\)     (square tube)

(Eq. 4)  \(\large{ W =  0.2836 \; t \; 144  }\)     (plate)

(Eq. 5)  \(\large{ W =  0.2225 \; d^2 \; t  }\)     (plate circle)

(Eq. 6)  \(\large{ W =  0.2904 \; t \; 144  }\)     (sheet)

(Eq. 7)  \(\large{ W =  3.403 \; t \; w  }\)     (flat bar)

(Eq. 8)  \(\large{ W =  2.945 \; d^2  }\)     (hexagon bar)

(Eq. 9)  \(\large{ W =  2.817 \; d^2  }\)     (octagon bar)

(Eq. 10)  \(\large{ W =  2.673 \; d^2  }\)     (round bar)

(Eq. 11)  \(\large{ W =  3.403 \; d^2  }\)     (square bar)

Where:

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

\(\large{ d }\) = diameter

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

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

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

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