Steel Pipe Schedule Weights

Steel tube weight table — ANSI / ASME pipe schedules (metric).

OD (mm) · wall thickness (mm) · weight (kg/m, plain-end mass). 5S / 10S / 40S / 80S figures based on austenitic steel (ASTM / API / ASME). Standards per ANSI B36.19 / B36.10.

12.7 wall thickness (mm) · 64.64 mass (kg/m) · – schedule not applicable
