The 2 7/8 drill pipe that is used in slim hole completions or work strings generally has different collars and is heavier.
Production tubing is what most people are building stuff like pens and panes out of.
Once a well doesn't have the bottom hole pressure to flow up the casing (like 4 1/2) they run a production string (2 3/8, 2 7/8, etc). Smaller ID pipe is easier to flow up because it can't hold the same amount of fluid which suppresses the well and can load it up.
After that when the well won't flow they add some sort of artificial lift to the tubing string like gas lift valves, jet pump, esp, plunger, rod pump, etc.
My family had little shallow gas wells that didn't make much and they had 1 1/2 pipe in them. They called is a velocity string.
The kicker is, tubing strings for wells are costly. It doesn't get changed out for no reason. They get eroded, or rod cut, or dont test, etc. Once pipe is exposed to h2s or co2 it's always imbeded in the pipe. When it's brought to surface and exposed to oxygen it starts to rust. High amounts of water flowed through pipe causes NORM.
You have to know where the tubing is coming from, especially now days. Most of the modern Shale play wells are dirty and not some where you would want tubing from.
