The Precision of Pipe Bending
When a standard pre-made pipe elbow won't work, fabricators must create custom bends. A common method is the segmented or miter bend, where straight sections of pipe are cut at an angle and welded together to form a curve. The accuracy of these cuts is paramount to achieving the correct final bend angle and radius. This calculator provides the essential measurements needed for this precise work.
Key Terms and Formulas
- Cutback: The crucial measurement. It's the amount of material to remove from the pipe to create the miter angle. Formula: `Cutback = OD * tan(Angle / (2 * Number of Segments))`
- Arc Length: The length of the bend along its centerline. This helps in determining the total amount of pipe required. Formula: `Arc Length = (2 * π * Radius) * (Angle / 360)`
- Tangent Length: The straight length of pipe from the start of the bend to the center point. Formula: `Tangent Length = Radius * tan(Angle / 2)`
