What is the difference between kink and bend?

Kink: a sharp bend with a small radius over a short distance. Bend: a gradual change in shape between the damaged and undamaged area. A part is considered kinked if, after straightening, there is a permanent area of deformation that will not return to its original state and shape without the use of excessive heat.

What is offset bend?

– An offset bend is two equal bends in opposite directions. It is used to avoid contacting a part of the structure or to bring the conduit out from the structure to match a knockout in a box or panel.

Is the kink or bend rule still in effect?

The kink versus bend guidance has grown more restrictive to reflect such new technology; this combined with further OEM straightening restrictions — which supercede I-CAR — seem to make the concept of straightening largely irrelevant. (“We don’t really talk about it a whole lot,” Bartanen said of the rule.)

What’s the difference between a kink and a bend?

The old rule said a bent part might be able to be straightened, while a kinked part should be replaced. However, even then, “you have to restore the state and shape,” Bartanen said.
