In the USA, 15mm is half-inch, and 22mm is three-quarters inch. Lengths of pipe nipples in these sizes range from one and a quarter/one and a half, to six inches, in half-inch increments.

What it's the take out off 12 inch 90
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.
Use a pair of plyers and two small pieces of cork to grab the threaded pipe while you rotate the female fitting. Also, if you don't need the threaded piece anymore, you can use a whole cork inserted into the threaded pipe with a bit of apoxy or super glue.

The take-off for a 4-inch 90-degree elbow is typically calculated based on the diameter of the pipe and the angle of the bend. For a 4-inch diameter pipe, the take-off is generally around 10 to 12 inches. This measurement may vary slightly depending on the specific design and manufacturer of the elbow, so it's always best to refer to the manufacturer's specifications for precise dimensions.

The take-off of an 8-inch 90 refers to the measurement of the distance from the centerline of a pipe or duct to the edge of the fitting at a 90-degree angle. Typically, for an 8-inch duct or pipe, the take-off dimension can vary based on the specific design and manufacturer, but it is generally around 6 to 8 inches. This measurement is crucial for ensuring proper airflow and fitting in HVAC or plumbing systems. Always check manufacturer specifications for precise dimensions.
