Weight of Steel Pipe per Meter

Steel Pipe Weight Formula:

\[ W = \rho \times \pi \times \frac{OD^2 - ID^2}{4} \]

Weight per Meter:

kg/m

1. What is Steel Pipe Weight Calculator?

Definition: This calculator estimates the weight per meter of a steel pipe based on its dimensions and material density.

Purpose: It helps engineers, construction professionals, and metal workers determine pipe weight for structural calculations and material planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \rho \times \pi \times \frac{OD^2 - ID^2}{4} \]

Where:

\( W \) — Weight per meter (kg/m)
\( \rho \) — Steel density (kg/m³)
\( OD \) — Outer diameter (meters)
\( ID \) — Inner diameter (meters)

Explanation: The formula calculates the cross-sectional area of the pipe wall and multiplies by density to get weight per unit length.

3. Importance of Pipe Weight Calculation

Details: Accurate weight calculations are essential for structural integrity, transportation planning, and cost estimation in construction projects.

4. Using the Calculator

Tips: Enter steel density (default 7850 kg/m³ for carbon steel), outer diameter, and inner diameter (0 for solid bar). All values must be positive with OD > ID.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for steel pipes?
A: Carbon steel is typically 7850 kg/m³, while stainless steel is about 8000 kg/m³.

Q2: How do I measure pipe diameters?
A: Measure outer diameter directly. For inner diameter, measure wall thickness and subtract twice from OD (ID = OD - 2×wall thickness).

Q3: What if my pipe is in millimeters?
A: Convert to meters by dividing by 1000 (e.g., 50mm = 0.05m) before entering values.

Q4: How do I calculate total pipe weight?
A: Multiply weight per meter by the total length of the pipe in meters.

Q5: What about non-steel pipes?
A: Use the appropriate density for your material (e.g., 2700 kg/m³ for aluminum).
