Concentric Bends
Concentric Bends Concentric Bends Concentric bends are a set of conduit bends that have a common center point, but have different centerline radii. Figure 1 shows three concentric bends produced from 2″ rigid conduit. Conduit 1 has a centerline radius of 20″. Conduit 2 has a centerline radius of 24 3/8″. Conduit 3 has […]
Center Of Bend
Center Of Bend How To Find Center of Bend Electricians often need to locate the center of a bend that they have made, or the center of a bend that needs to be matched or aligned with a new bend. A small torpedo level or straight edge is laid along the inside of […]
Offset Bends
Offset Bends Offsets Offset bends are used to move a run of conduit from one plane to another. An offset is normally used to bend the conduit around an obstruction, or to relocate the conduit close to a structural member to make it easier to fasten the conduit. Figure 2 shows an example of […]
Segment Bends
Sample method to bend 3-1/2″ rigid conduit around a storage tank with a diameter of 160 feet. Segment bending is a method of bending conduit by making several small bends to produce one larger bend. The method on this page illustrates a technique for bending a 3-1/2″ rigid conduit around a tank with a […]
StackedKicksSample
Stacked Kicks Sample The drawing below illustrates 4 x 3in. EMT Conduits that are kicked from an overhead pipe rack to drop into an electrical distribution panel. The outside diameter of the conduits is 3-1/2 inches. The Center to Center distance of the first kick is 30 inches, and each subsequent conduit is […]

Conduit Bending
Conduit bending is the process of shaping electrical conduit into various forms in order to complete an installation. This can be done by hand, using a variety of hand tools specifically designed for the task, or by machine, using a conduit bender. The electrical trade generally uses rigid conduit, which is available in a variety […]
