If we divide that into 18 into 5º bends, we will have the 90º bend we need (18 * 5 = 90). Dividing 28.2" by 18 bends, we see that each bend should be 1.57" apart - we'll round that off to 1.5" apart. Now that's about the minimum possible using a ½" conduit bender, but the fact that we will be making only 5º bends helps.Multipliers for Conduit Offsets Math From Triangles Most conduit bends, in addition to a simple 90-degree bend, can be understood and calculated using the geometry of a right triangle.

A k-factor average of 0.4468 is used for most bending applications. Step 5: You’ve measured the Ir. To find side a of the blue triangle, calculate for the inside setback (ISSB): ISSB = [tangent (external bend angle/2) × Ir. Step 6: You know side a of the blue triangle is the ISSB.With an increase in the bend radius, the SIF decreases and finally reaches 1.0 for the straight pipe. The SIF for a 45-degree elbow and a 90-degree elbow is the same and the bend radius is the same. With an increase in nominal pipe thickness or schedule, the SIF of a bend (90-degree) keeps on decreasing till its value is equal to 1.0.I always mark my hand benders with the center marks for 5, 10, 15 and 30 degrees. This makes bending faster, more neat, and easier to match multiple runs. On my usual 3/4 ENT bender, a 2 inch offset on 30 degrees is the minimum offset.
