The Math Behind the Calculator
To calculate the theoretical weight of carbon steel pipe, this tool uses the standard industry formula based on the density of carbon steel (0.2833 lbs/in³).
The Plain End Weight Formula:
Weight (lbs/ft) = (Outside Diameter - Wall Thickness) × Wall Thickness × 10.69
Understanding the Variables:
- Outside Diameter (OD): The measurement across the entire width of the pipe, in inches.
- Wall Thickness: The thickness of the steel itself, in inches. Note: Do not confuse Wall Thickness with Schedule (e.g., Schedule 40). You must look up the exact decimal wall thickness on a pipe chart first.
- 10.69 Constant: This is a conversion factor derived from the density of standard carbon steel and Pi ($$\pi$$), simplifying the calculation from cubic inches into pounds per linear foot.
