Pipe Weight Calculator

Formula

W = π × (OD/2)² × ρ_steel − π × (ID/2)² × ρ_steel where OD = outside diameter (m), ID = OD − 2 × wall (m), ρ_steel = 7850 kg/m³.

Variables

• OD — pipe outside diameter (mm)
• Wall — pipe wall thickness (mm)
• Length — total pipe length (m)

Example

DN150 (OD 168.3 mm, wall 7.11 mm, SCH 40), 6 m length: weight ≈ 28.3 kg/m, total ≈ 169.7 kg.

Application

Useful for procurement estimation, structural load calculations, shipping weight and crane lift planning for piping systems.

Limitations

Uses steel density 7850 kg/m³. Actual weight varies by steel grade, manufacturing tolerances and coating. For alloy, stainless or coated pipes, adjust density accordingly.
