1. What is MS Hollow Pipe Weight Calculator?

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

Purpose: It helps engineers, construction professionals, and fabricators determine pipe weights 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:

\( W \) — Weight of pipe (kilograms)
\( \rho \) — Material density (kg/m³, default 7850 for mild steel)
\( OD \) — Outer diameter (meters)
\( ID \) — Inner diameter (meters)
\( L \) — Length of pipe (meters)

Explanation: The formula calculates the volume of the pipe material (cross-sectional area × length) and multiplies by density to get weight.

3. Importance of Pipe Weight Calculation

Details: Accurate weight calculations are crucial for structural integrity, transportation logistics, cost estimation, and load-bearing capacity assessments.

4. Using the Calculator

Tips: Enter all dimensions in meters. For MS pipes, density is typically 7850 kg/m³. Ensure OD > ID for valid hollow pipes.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I convert pipe dimensions from mm to meters?
A: Divide mm values by 1000 (e.g., 100mm OD = 0.1 meters).

Q3: Can this calculator be used for solid rods?
A: Yes, set ID = 0 for solid rods or bars.

Q4: How accurate is this calculation?
A: It provides theoretical weight. Actual weight may vary slightly due to manufacturing tolerances.

Q5: What if I need weight per meter?
A: Set length = 1 meter in the calculator.
