Home – Welded Steel Pipe – Steel Pipe Weight Calculator

Steel Pipe Weight Calculator

Theoretical weight for carbon & alloy steel pipe (ASTM / API 5L). Enter dimensions in mm.

Outside dia (mm)

Wall thickness (mm)

Length per pipe (m)

Quantity (pcs)

kg / metre

kg / pipe

tonnes total

Theoretical weight = (OD − wall) × wall × 0.02466 (steel 7.85 g/cm³). Synbase bills on actual weight verified at port — request a quote to compare against theoretical.
