Emt Pipe Bending Calculations

1 2 Emt Offset Chart. Emt Bending Guide The formula shown in the chart below indicates that for each inch of outside diameter of the obstruction, you must move your center mark ahead If bending at 10 degrees, the conduit will shrink 1/16" for every inch of rise

The sine of 22º = .3846, and 1 / .3846 = 2.6, which is the familiar multiplier for a 22º offset. 15 degrees is 1/8" for every inch, 22.5 is 3/16", 30 is 1/4", 45 is 3/8" and 60 is 1/2"

Pipe Bending Chart For Offsets. Note that this can also be written as C = A * (1 / sine(22º)) Example: For a 4" offset height at 30 degrees, place your first mark at the distance from the obstacle then add your shrinkage calculation
