1. What is a Unit Weight Calculator of Hollow Square Pipe?

Definition: This calculator estimates the unit weight (per meter length) of hollow square pipes based on side length, wall thickness, and material density.

Purpose: It helps engineers and construction professionals determine the weight of hollow square pipes for structural calculations and material estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Side — Length of one side of the square pipe (meters)
• Thickness — Wall thickness of the pipe (meters)
• Density — Material density (kg/m³, default 7850 for steel)

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

3. Importance of Unit Weight Calculation

Details: Accurate weight calculation is essential for structural design, load calculations, transportation planning, and cost estimation.

4. Using the Calculator

Tips: Enter the side length, wall thickness (both in meters), and material density (kg/m³). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the default density value based on?
A: The default 7850 kg/m³ is the density of mild steel, commonly used for structural pipes.

Q2: How do I calculate for rectangular pipes?
A: Use a different formula: 2 × (Width + Height - 2 × Thickness) × Thickness × Density.

Q3: Does this account for pipe corners?
A: This is a simplified calculation that assumes sharp corners. Actual weight may be slightly higher due to rounded corners.

Q4: What units should I use?
A: All length measurements should be in meters, density in kg/m³, resulting in kg/m unit weight.

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