*
Bend Radius: The bend radius refers back to the minimal distance inside which the conduit could be bent. Contemplate the tightest bend you might want to make and select a bender that may accommodate it.
*
Ease of Use: Handbook benders require extra effort and precision, whereas powered benders are simpler to function. Choose a bender that balances ease of use along with your talent stage and mission necessities.
*
Options: Some conduit benders provide further options comparable to adjustable settings, computerized shut-off, and built-in measuring scales. Contemplate the options that will improve your bending expertise.
*
Value: Conduit benders vary in value relying on their kind, capability, and options. Set a finances and contemplate the cost-benefit ratio earlier than making a purchase order.

| Bender Kind | Conduit Dimension | Effort Stage | Pace | Precision |
|---|---|---|---|---|
| Handbook | As much as 2″ | Excessive | Gradual | Good |
| Electrical | As much as 6″ | Low | Medium | Very Good |
| Hydraulic | Giant diameters | Low | Quick | Glorious |
Positioning the Conduit within the Bender
Correct positioning of the conduit within the bender is essential for correct and efficient bending.
- Measure and Mark: Decide the specified bend radius and mark the corresponding location on the conduit with a marker or pencil.
- Insert into the Bender: Open the bender and insert the conduit into the bending shoe, aligning the marked location with the middle of the shoe.
- Safe the Conduit: Use the bender’s handles or clamp to safe the conduit firmly in place.
- Tighten the Shoe: Step by step tighten the bending shoe to carry the conduit snugly with out damaging it.
- Deal with Placement: Grip the bender handles on the specified distance from the bending shoe, as indicated by the producer’s directions or markings on the bender. This distance determines the bend radius.
Deal with Placement Distance Chart Bend Radius Deal with Distance from Bender Shoe 1 inch 3 inches 1.5 inches 5 inches 2 inches 7 inches Making use of the Appropriate Strain
Making use of the correct quantity of strain is essential for attaining a easy and correct bend with out damaging the conduit. Comply with these steps:
Bend Constantly
Preserve a constant quantity of strain all through the bending course of. Keep away from making use of an excessive amount of strain firstly or finish of the bend, as this may end up in an uneven bend.
Use Gradual Pressure
Begin by making use of mild strain and step by step improve it as wanted. Keep away from making use of extreme power, as this will deform or crush the conduit.
Calculate the Radius
The quantity of strain required is determined by the thickness of the conduit and the specified radius of the bend. Consult with a conduit bending chart or use a bending instrument to find out the suitable strain to your particular state of affairs.
Use a Rubber Pad
If obligatory, place a rubber pad or different mushy materials between the conduit and the bending instrument to distribute the strain evenly and stop burring.
Take a look at the Bend
After you have made the bend, examine it for any irregularities or injury. If the bend will not be easy or uniform, regulate the strain and check out once more.

8. Kinks
Kinks are sharp bends that may weaken the conduit and make it extra vulnerable to break. To forestall kinks, all the time bend the conduit step by step and easily. In the event you do create a kink, you possibly can attempt to take away it by fastidiously bending the conduit again in the wrong way. Nonetheless, if the kink is just too extreme, you might want to switch the part of conduit.
Trigger Resolution Bending the conduit too sharply Bend the conduit step by step and easily Utilizing the improper bending instrument Use the right bending instrument for the scale and kind of conduit you might be utilizing Making use of an excessive amount of power Bend the conduit utilizing regular and even strain Listed here are some further suggestions for stopping bends in conduit:
- Use a conduit bender that’s designed for the scale and kind of conduit you might be utilizing.
- Bend the conduit step by step and easily. Don’t apply an excessive amount of power.
- In the event you do create a bend, you possibly can attempt to take away it by fastidiously bending the conduit again in the wrong way. Nonetheless, if the bend is just too extreme, you might want to switch the part of conduit.
Find out how to Bend a Conduit
Conduits are important for safeguarding electrical wires and cables from injury. Correct bending of conduits ensures a neat {and professional} set up. This is a step-by-step information on the right way to bend a conduit:
Instruments Required:
- Conduits
- Conduit bender
- Measuring tape
- Pencil or marker
Steps:
