The available lengths for threadless copper pipe is 20 foot for sizes to 10 with 12 being furnished in 15 foot lengths.
Dwv copper pipe wall thickness.
The outside diameter of threadless copper pipe tp is essentially the same as schedule 40 pipe although the wall thickness is much less than that for the same size pipe.
K l m and dwv.
It is true with all three common types of new pipe k l and m.
The letters indicate in part the relative thickness of the pipe wall from thickest to thinnest.
Lightweight copper pipe and tubing resists corrosion and is suitable for plumbing refrigeration and hvac applications.
It also has thinner walls than the other types of copper pipe with a wall thickness of 040 for a piece of 1 inch pipe the smallest diameter available for dwv.
Type dwv copper pipe and tubing.
Wall thickness 0 04 in 1 0 042 in 2 0 045 in 1 0 058 in 1 inside dia.
The actual wall thickness depends on the size of the pipe.
For example a 1 2 inch copper pipe has an outside diameter of 5 8 inch.

The inside diameter id of copper pipe is determined by the wall thickness of the pipe which varies by the pipe type.
