    For example, DN20 is the size for copper pipe with an outside diameter of 19.05 mm or 34 inch. While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 34 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a ...

    The history of copper pipe is similar. In the 1930s, the pipe was designated by its internal diameter and a 1 ⁄ 16-inch (1.6 mm) wall thickness. Consequently, a 1-inch (25 mm) copper pipe had a 1 + 1 ⁄ 8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings.

    These are strong but flexible springs inserted into a pipe to support the pipe walls during manual bending. They have diameters only slightly less than the internal diameter of the pipe to be bent. They are only suitable for bending 15-and-22 mm (0.6-and-0.9 in) soft copper pipe (typically used in household plumbing) or PVC pipe.
