Hollow Circular Section Weight Calculator – CHS Pipe

The Hollow Circular Section (CHS) Calculator helps you calculate the weight of hollow steel tubes and pipes using diameter, thickness, and length.

📊 What is CHS?

CHS (Circular Hollow Section) is widely used in structural engineering, construction, and fabrication due to its high strength and uniform shape.

📐 Formula Used

Weight per meter = π × (D − t) × t × Density

Where density of steel ≈ 7850 kg/m³

📊 Example

🎯 Why Use This Tool?

• Accurate tube weight calculation
• Useful for construction and fabrication
• Quick estimation
• Saves time and cost

⚠️ Important Note

Thickness must be less than half of the diameter to maintain a hollow section.
