MS Pipe Weight Calculator in kg/mtr

Pipe Weight Formula:

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

Weight per Meter: kg/m

1. What is a MS Pipe Weight Calculator?

Definition: This calculator estimates the weight per meter of mild steel (MS) pipes based on their dimensions and material density.

Purpose: It helps engineers, fabricators, and construction professionals determine pipe weight for structural calculations, transportation, and material estimation.

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 density to get weight per unit length.

3. Importance of Pipe Weight Calculation

Details: Accurate weight calculations are essential for structural design, load-bearing capacity, transportation logistics, and cost estimation.

4. Using the Calculator

Tips: Enter the material density (default 7850 kg/m³ for mild steel), outer diameter, and inner diameter in meters. For solid bars, enter inner diameter as 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the density of mild steel?
A: The standard density for mild steel is 7850 kg/m³, which is the default value in the calculator.

Q2: How do I calculate weight for solid bars?
A: Enter the outer diameter as the bar diameter and set inner diameter to 0.

Q3: Can I use this for other materials?
A: Yes, just change the density value (e.g., 2700 kg/m³ for aluminum, 8960 kg/m³ for copper).

Q4: What units should I use?
A: All dimensions must be in meters (1 inch = 0.0254 meters). The result is in kg/m.

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