50 NB weight by class

Pieces per tonne ≈ round(1000 ÷ kg per 6 m length). Use for rough logistics only; actual count depends on exact length and mill mass.
GI pipe weight note for 50 NB
Galvanized (GI) pipe is MS pipe with a zinc coating. Zinc typically adds roughly 3–6% mass over the plain-end MS weight depending on coating class and surface area. Use the MS figures below as the base; for GI orders expect a small uplift, or confirm coated mass on the mill test certificate (MTC).
Formula with 50 NB dimensions
W = (OD − WT) × WT × 0.02466, with OD = 60.3 mm for this size:
- Class A: (60.3 − 2.9) × 2.9 × 0.02466 = 4.10 kg/m
- Class B: (60.3 − 3.6) × 3.6 × 0.02466 = 5.03 kg/m
- Class C: (60.3 − 4.5) × 4.5 × 0.02466 = 6.19 kg/m
