What is the multiplier for 1/2 EMT?
The errors in distance between bends for a 30 inch high offset varied from 1/16 of an inch for 1/2 inch EMT with a 30 degree offset to 4 inches for 5 inch rigid pipe with a 60 degree offset….Mathematics of the Offset Bend.
| Degree of Bend in Degrees (Angle) | Multiplier | Shrinkage Multiplier in inches |
|---|---|---|
| 22.5 | 2.6 | 3/16 |
| 30 | 2 | 1/4 |
| 45 | 1.4 | 3/8 |
| 60 | 1.2 | 1/2 |
What is the take up on a 90 degree bend?
Take-up is a constant, and changes only with pipe size. To bend a ninety degree bend, you first determine your desired stub height. Then, you subtract the take-up for the size pipe that you are bending from the desired stub height and mark the pipe. Then, using a tape measure, measure from the end of the pipe back 10”.
What’s the formula for a rolling offset?
To find the travel length of a rolling offset with 1-foot horizontal offset and 1-foot vertical offset using a 45-degree bent fitting: Square the horizontal and vertical offsets and add them together like so: 1² + 1² = 2.
