1. What is MS ERW B Class Pipe Weight Calculator?

Definition: This calculator computes the weight of Mild Steel Electric Resistance Welded (ERW) B Class pipes based on their dimensions and material density.

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

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 material density to get weight.

3. Importance of Pipe Weight Calculation

Details: Accurate weight estimation is crucial for structural support design, transportation logistics, cost estimation, and load-bearing calculations.

4. Using the Calculator

Tips:

  • Default density is 7850 kg/m³ for mild steel
  • Enter diameters in meters (e.g., 0.1m for 100mm pipe)
  • For solid rods, set ID = 0
  • OD must be greater than ID

5. Frequently Asked Questions (FAQ)

Q1: What is MS ERW B Class pipe?
A: Mild Steel Electric Resistance Welded pipe meeting B Class specifications, commonly used for structural and fluid transportation applications.

Q2: Why is density important?
A: Different materials have different densities. Mild steel is typically 7850 kg/m³, while stainless steel is about 8000 kg/m³.

Q3: How do I measure pipe diameters?
A: Measure OD directly with calipers. ID can be calculated from OD and wall thickness (ID = OD - 2×thickness).

Q4: Can this calculate weight per meter?
A: Yes, set length = 1 meter to get weight per meter.

Q5: What about pipe fittings?
A: This calculates straight pipe weight only. Fittings require different calculations based on their geometry.
