5. Bend Slowly and Gently
Don’t overbend the tube or bend it too rapidly. Bending too aggressively could cause the tube to interrupt or crack.
6. Test the Bend Angle
Use an angle gauge or a protractor to measure the bend angle. Be certain the angle matches the specified specification.
7. Stress Relieve the Tube
Heating the tube after which cooling it slowly relieves any residual stresses which will have been induced throughout the bending course of. This helps forestall the tube from cracking or distorting over time.
8. Examine the Completed Bend
As soon as the tube is bent, examine it rigorously for any defects, akin to cracks, scratches, or distortions. Any imperfections can impression the tube’s efficiency or longevity.
9. Stress Check the Tube
If mandatory, conduct a stress check on the tube to make sure it meets the required specs. This check helps establish any weak factors or leaks.
10. Troubleshooting: Tube Kinking
If the tube kinks throughout bending, this means that the bend radius is simply too tight or the tube is being bent too sharply. To resolve the problem, enhance the bend radius, lubricate the tube additional, or use a distinct bending method.
| Tight bend radius | Improve the bend radius |
| Inadequate lubrication | Apply extra lubricant to the tube and bending instrument |
| Improper bending method | Use a distinct bending method, akin to a mandrel bender |
