The following are the specifications of some common LSAW steel pipes and their corresponding theoretical weights (unit: kg/m):

Φ48×2.5: 2.91 kg/m

Φ57×3: 4.03 kg/m

Φ76×3.5: 6.22 kg/m

Φ89×4: 8.36 kg/m

Φ108×4: 10.9 kg/m

These data are calculated according to the formula: `theoretical weight (kg/m) = (OD – wall thickness) × wall thickness × 0.02466`.
