Pick a nominal pipe size and schedule, or enter any outside diameter and wall thickness, to get steel pipe weight per metre and per length.
Steel pipe weight (density 7850 kg/m³)5.44 kg/m
OD 60.30 mm · wall 3.91 mm · ID 52.48 mm · 3.654 lb/ft · total for 6 m: 32.6 kg
Nominal dimensions only — check the mill certificate and actual wall tolerance before ordering or designing supports. This is a weight estimate, not a pressure rating.
Formula
Weight per metre = π/4 × (OD² − ID²) × density, with ID = OD − 2 × wall thickness and steel density 7850 kg/m³.
Standard / source
Nominal pipe sizes, outside diameters and schedule wall thicknesses follow ASME B36.10M. The schedule presets here cover common sizes; always confirm the ordered schedule against the project specification.
Worked example
2″ Schedule 40 pipe: OD 60.3 mm, wall 3.91 mm, ID 52.48 mm. Cross-sectional area ≈ 692.7 mm², so weight ≈ 692.7 × 10⁻⁶ × 7850 ≈ 5.44 kg/m.
Safety note
This is a weight and ordering estimate, not a pressure rating. Wall thickness for pressure service must be checked against the applicable piping code — a weight number never approves a pipe for pressure.
