Estimate the weight of MS, GI, CR and SS pipes and tubes in kg per metre, per piece and in total. Works for round pipes, square tubes and rectangular tubes.
Formulas used
- Round: kg/m = (OD − t) × t × π × ρ / 1000
- Square / rectangular: kg/m = t × (2 × (A + B) − 4t) × ρ / 1000
- ρ = density in g/cm³ (7.85 carbon steel, 7.93 SS 304, 7.98 SS 316)
