1. What is a Tube Bend Length Calculator?

Definition: This calculator computes the arc length of a tube bend based on the bend angle and radius.

Purpose: It helps engineers, fabricators, and metalworkers determine the developed length of a bent tube section.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Arc length (inches)
• \( θ \) — Bend angle (degrees)
• \( R \) — Bend radius (inches)
• \( \pi \) — Mathematical constant (~3.14159)

Explanation: The formula converts the angle from degrees to radians, then multiplies by the radius to get arc length.

3. Importance of Tube Bend Length Calculation

Details: Accurate bend length calculations ensure proper material usage, correct tube positioning, and precise fabrication.

4. Using the Calculator

Tips: Enter the bend angle in degrees and bend radius in inches. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between bend radius and tube radius?
A: Bend radius is the centerline radius of the curved portion, while tube radius is half the tube's diameter.

Q2: Does this work for any bend angle?
A: Yes, from 1° to 360° (full circle). For angles > 360°, the physical meaning may not apply.

Q3: How do I measure bend radius?
A: Measure from the center of curvature to the centerline of the tube.

Q4: Does material thickness affect the calculation?
A: Not directly in this formula, but material properties affect the minimum possible bend radius.

Q5: Can I use this for pipe bending?
A: Yes, the same formula applies to pipes when using centerline dimensions.
