1. What is Pipe Weight Per Meter?

The pipe weight per meter calculation determines the mass of a pipe per unit length based on its dimensions and material density. This is essential for engineering, construction, and transportation planning.

2. How Does the Calculator Work?

The calculator uses the pipe weight formula:

Where:

• \( OD \) — Outer diameter in millimeters (mm)
• \( ID \) — Inner diameter in millimeters (mm)
• \( Density \) — Material density in grams per cubic centimeter (g/cm³)
• 1000 — Conversion factor (mm² to m² and g to kg)

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

3. Importance of Pipe Weight Calculation

Details: Accurate pipe weight calculation is crucial for structural engineering, transportation logistics, cost estimation, and load-bearing capacity assessments.

4. Using the Calculator

Tips: Enter outer diameter (OD) and inner diameter (ID) in millimeters, and material density in g/cm³. Common densities: Steel=7.85, Aluminum=2.7, Copper=8.96.

5. Frequently Asked Questions (FAQ)

Q1: What if my pipe is solid (no ID)?
A: For solid rods, set ID=0. The formula simplifies to π×OD²/4×density.

Q2: How accurate is this calculation?
A: It's theoretically exact for homogeneous materials with precise dimensions. Real pipes may vary slightly due to manufacturing tolerances.

Q3: Can I use this for non-circular pipes?
A: No, this formula is specific to circular pipes. Different formulas are needed for square, rectangular, or other profiles.

Q4: What units should I use?
A: The calculator expects OD and ID in millimeters, density in g/cm³, and returns weight in kg/m.

Q5: How does pipe length affect total weight?
A: Total weight = weight per meter × length in meters. This calculator gives the per-meter value.
