1. What is MS Hollow Pipe Weight Calculator?

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

Purpose: It helps engineers, fabricators, and construction professionals determine pipe weight for structural calculations and material 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, 7850 for mild 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 integrity, transportation planning, and cost estimation in construction projects.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the standard density for mild steel?
A: 7850 kg/m³ is standard for mild steel (carbon steel). Use 2700 kg/m³ for aluminum, 8000 kg/m³ for stainless steel.

Q2: How do I measure pipe diameters?
A: Measure outer diameter directly. Inner diameter is OD minus twice the wall thickness.

Q3: What if my pipe is solid (no inner diameter)?
A: Set inner diameter to 0 to calculate solid rod weight.

Q4: Can I use millimeters instead of meters?
A: Yes, but convert all dimensions to meters (divide mm values by 1000) for consistent units.

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