Weight of GI Pipe per Metre

GI Pipe Weight Formula:

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

Weight per Meter:

1. What is GI Pipe Weight 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 and transportation needs.

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, 7850 for steel)
\( OD \) — 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 support design, transportation planning, and cost estimation in piping projects.

4. Using the Calculator

Tips: Enter the material density (default 7850 kg/m³ for steel), outer diameter, and inner diameter in meters. All values must be > 0 and OD > ID.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for GI pipes?
A: Standard steel density is 7850 kg/m³. Galvanization 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: Can I use this for other pipe materials?
A: Yes, just change the density value (e.g., 2700 kg/m³ for aluminum, 8960 kg/m³ for copper).

Q4: What if I know wall thickness instead of ID?
A: Calculate ID as OD minus twice the wall thickness before using the calculator.

Q5: How accurate is this calculation?
A: It's theoretically exact for uniform materials. Real pipes may vary slightly due to manufacturing tolerances.
