Formula for calculating the weight of steel pipes per meter
Formula for calculating the weight of square tubes:
4 × wall thickness × (Side length wall thickness) × 7.85/1000 kg/m
For example, 50 × 50 × 4mm square tube weight is: 4 × 4 × (50-4) × 7.85/1000 kg/m=5.77 kg/m
Formula for calculating the weight of rectangular tubes:
2 × (Side length 1+Side length 2- Wall thickness) × wall thickness × length × Density kg/m/1000
For example, 60 × 40 × 4mm rectangular tube weight is:
2 × (60+40-4) × 4 × 1 × 7.85 kg/m/1000=6.0288 kg/m
Usually, this calculation company calculates a weight that is greater than the actual weight.
There is also a calculation formula for square and rectangular steel pipes:
There is also a formula for calculating the weight per meter for square and rectangular steel pipes:
（2 × (Side length 1+Side length 2)/3.14- Wall thickness) × Wall thickness × 0.0246615 × Length/1000
Formula for calculating the weight of circular pipes:
(Outer diameter - wall thickness) × Wall thickness × 0.0246615 × Length/1000
For example, 2032 × 40mm round tube weight is:
(2032-40)×40×0.0246615×1/1000=1.96502832 Ton/M
