Tufnol Rods


Calculate the approximate weight of TUFNOL rods as follows:


Calculate weight in kg.

D = diameter in mm

L = length in mm

G = specific gravity for grade (see above)


Weight in kg = 0.007854 x D2 x L x G



Calculate weight in pounds

D = diameter in inches

L = length in inches

G = specific gravity for grade (see above)


Weight in pounds = 0.02837 x D2 x L x G



Tufnol Tubes


Calculate the approximate weight of TUFNOL tubes as follows:


Calculate weight in kg.

D = Outside diameter in mm

d = inside diameter in mm

L = length in mm

G = specific gravity for grade (see above)


Weight in kg = 0.007854 x (D2 – d2) x L x G



Calculate weight in pounds

D = diameter in inches

L = length in inches

G = specific gravity for grade (see above)


Weight in pounds = 0.02837 x (D2 – d2) x L x G
