1. What is MS Hollow Pipe Unit Weight Calculator?

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

Purpose: It helps engineers, architects, and construction professionals determine pipe weights for structural calculations 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 unit length (kg/m)
  • \( \rho \) — Material density (kg/m³, default 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 meter.

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 MS), outer diameter, and inner diameter in meters. All values must be positive, and OD must be greater than 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, which is the default value in the calculator.

Q2: How do I measure pipe diameters?
A: Measure the outside diameter directly. For inner diameter, subtract twice the wall thickness from the OD.

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

Q4: Can I use this for other materials?
A: Yes, just change the density value to match your material (e.g., 2700 kg/m³ for aluminum).

Q5: How do I calculate total pipe weight?
A: Multiply the result by the pipe length in meters to get total weight in kg.
