1. What is a Tube Bending Arc Length Calculator?

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

Purpose: It helps metalworkers, plumbers, and engineers calculate the developed length of a tube bend for fabrication and installation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L \) — Arc length (inches)
• \( θ \) — Bend angle (degrees)
• \( R \) — Bend radius (inches)
• \( \pi \) — Pi (approximately 3.14159)

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

3. Importance of Arc Length Calculation

Details: Accurate arc length calculation ensures proper tube bending, prevents material waste, and helps in precise measurements for installations.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between bend radius and arc length?
A: Bend radius is the distance from the center of curvature to the centerline of the tube, while arc length is the actual length along the curved portion.

Q2: Does this work for any bending angle?
A: Yes, the formula works for any angle from 0° to 360°.

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

Q4: Can I use this for pipe bending too?
A: Yes, the same formula applies to both tube and pipe bending.

Q5: What if my tube has multiple bends?
A: Calculate each bend separately and sum the straight sections between bends for total length.
