How to use the calculator
- Enter the offset distance (L) - the horizontal distance you want to achieve between the entry and exit points of the tube.
- Enter the bend angle (θ) - the angle at which you want to bend the tube.
- Enter the tube diameter (D) - the outer diameter of your tube or pipe.
- Enter the tube wall thickness (t) - the thickness of the tube walls.
- Click the "Calculate" button to compute the required bend radius and other parameters.
- Use the "Reset" button to clear all inputs and start over.
Working Principle
Offset bending is a technique used in pipe and tube bending to change the direction of the tube while maintaining a specified horizontal offset distance. The calculator uses the following formula to determine the required bend radius:
R = L/(2×tan(θ/2)) + D/2
Where R is the bend radius, L is the offset distance, θ is the bend angle, and D is the tube diameter.
Important Considerations
- The calculated bend radius is the minimum radius that will achieve the desired offset while maintaining the specified bend angle.
- The maximum stress calculation is simplified and assumes elastic behavior. For precise applications, consider consulting material specifications.
- The safety factor indicates how much stress the actual bending will produce compared to the material's allowable stress. A value less than 1 indicates potential failure.
- This calculator is primarily for tubes with constant diameter. For more complex bending scenarios, consult engineering handbooks.
