pipe size(inch)x38.1
The take-off for a standard radius 90 is one and one half the diameter of the pipe. Example: 6 inch 90 has a take- off of 9 inches. The take-off for short radius 90 would be the dia. of the pipe. Long radius 90 is 2 times the pipe diameter.
It's your pipe size multiplied by 1.5
Measure to the center of the Ell and decuct for the threads ..

If it is 3 in. Then take off 3 in. and so on for what ever size you are use if it is 2 in. then 2 in.
The take-off for a 30-degree elbow can be calculated using the formula: Take-off = Pipe Diameter × 0.577. For example, if the pipe diameter is 4 inches, the take-off would be 4 × 0.577 = 2.308 inches. This formula helps determine the horizontal run of the pipe after the elbow joint.
