1. What is GI Pipe Weight per Meter Calculator?

Definition: This calculator estimates the weight per meter of galvanized iron (GI) pipes based on their dimensions and material density.

Purpose: It helps engineers, plumbers, and construction professionals determine pipe weight for structural calculations, transportation, and installation 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)
  • \( \rho \) — Material 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 it by material density to get weight per unit length.

3. Importance of Pipe Weight Calculation

Details: Knowing pipe weight is crucial for structural support design, transportation logistics, and installation equipment selection.

4. Using the Calculator

Tips: Enter material density (default 7850 kg/m³ for steel), outer diameter, and inner diameter in meters. All values must be positive, and OD must be greater than ID.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for GI pipes?
A: Standard density is 7850 kg/m³ for steel. The galvanized coating adds minimal weight (typically 1-3%).

Q2: How do I measure pipe diameters?
A: Measure OD directly with calipers. ID can be calculated as OD minus twice the wall thickness.

Q3: What if my pipe is solid (no inner diameter)?
A: Set ID to 0 for solid rods or bars.

Q4: Does this account for pipe fittings?
A: No, this calculates straight pipe only. Fittings typically add 20-30% to total weight.

Q5: How accurate is this calculation?
A: Very accurate for theoretical weight. Actual weight may vary slightly due to manufacturing tolerances.
