Pipe Weight Chart (Per Foot/Meter)

Steel pipe weight varies by nominal pipe size (NPS), wall thickness (schedule), and material density. The following charts list the weight per foot (lb/ft) and weight per meter (kg/m) for carbon steel pipes across the most common schedules, from Sch 10 to XXS. All values are based on ASME B36.10M nominal dimensions and a carbon steel density of 7.85 g/cm3.

Pipe Weight Formula

The weight per meter of a steel pipe can be calculated using the following formula:

W = 10.69 x (OD - WT) x WT

Where:

• W = weight per meter (kg/m)
• OD = outside diameter (mm)
• WT = wall thickness (mm)
• 10.69 is the constant derived from the steel density of 7.85 g/cm3

To convert from kg/m to lb/ft, multiply by 0.672 (1 kg/m = 0.672 lb/ft).

Notes

• All weights are calculated based on carbon steel with a density of 7.85 g/cm3 (0.2836 lb/in3) and nominal wall thickness per ASME B36.10M.
• For stainless steel pipes (ASME B36.19M), multiply the carbon steel weight by the density ratio of the specific alloy. For example, Type 304/316 stainless steel has a density of approximately 8.00 g/cm3, so multiply by 1.019.
• STD (Standard Weight) equals Sch 40 for NPS 1/2 through NPS 10. For NPS 12 and above, STD corresponds to a fixed wall thickness of 3/8 inch (9.53 mm), which is less than Sch 40.
• XS (Extra Strong) equals Sch 80 for NPS 1/2 through NPS 8. For NPS 10 and above, XS corresponds to a fixed wall thickness of 1/2 inch (12.70 mm).
• XXS (Double Extra Strong) has no direct schedule equivalent but is defined per ASME B36.10M for NPS 1/2 through NPS 12. For NPS 14 and above, XXS is generally not defined.
• A dash (-) indicates that no standard wall thickness is defined for that combination of pipe size and schedule per ASME B36.10M.
• Actual pipe weight may vary within the manufacturing tolerance specified by the applicable product standard (e.g., ASTM A106, ASTM A53, API 5L).
