1. What is SS 304 ERW Pipe Weight Calculator?

Definition: This calculator estimates the weight of stainless steel 304 ERW (Electric Resistance Welded) pipes based on their dimensions and material density.

Purpose: It helps engineers, fabricators, and construction professionals determine pipe weights for structural calculations, transportation, and cost estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

  • \( W \) — Pipe weight (kilograms)
  • \( \rho \) — Density of SS 304 (kg/m³, default 7930)
  • \( OD \) — Outer diameter (meters)
  • \( ID \) — Inner diameter (meters)
  • \( L \) — Pipe length (meters)

Explanation: The formula calculates the cross-sectional area of the pipe wall and multiplies by length and density to get total weight.

3. Importance of Pipe Weight Calculation

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

4. Using the Calculator

Tips: Enter all dimensions in meters. Default density is for SS 304 (7930 kg/m³). For solid rods, set ID to 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the density of SS 304?
A: The typical density is 7930 kg/m³, but it can vary slightly based on composition.

Q2: How do I convert inches to meters?
A: Multiply inches by 0.0254 to get meters (1" = 0.0254m).

Q3: What's the difference between ERW and seamless pipes?
A: ERW pipes are welded, while seamless pipes are extruded. Both can use the same weight calculation.

Q4: How do I calculate for multiple pipes?
A: Multiply the result by the number of identical pipes needed.

Q5: Can I use this for other materials?
A: Yes, just change the density value (e.g., 7850 kg/m³ for carbon steel).
