1. What is MS Hollow Circular Pipe Weight Calculator?

Definition: This calculator estimates the weight of mild steel (MS) hollow circular pipes based on 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:

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

Where:

\( W \) — Pipe weight (kilograms)
\( \rho \) — Material density (kg/m³)
\( OD \) — Outer diameter (meters)
\( ID \) — Inner diameter (meters)
\( L \) — Pipe length (meters)

Explanation: The formula calculates the volume of the pipe wall (annular area × length) and multiplies by density to get weight.

3. Importance of Pipe Weight Calculation

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

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for mild steel?
A: Mild steel typically has a density of 7850 kg/m³ (7.85 g/cm³).

Q2: How do I calculate for solid pipes?
A: Set Inner Diameter (ID) to 0 for solid pipe calculations.

Q3: Can I use this for other materials?
A: Yes, just input the correct density (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 (m) for consistent results in kilograms (kg).

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