That's not what Anon meant by "copper".

What you need to make sure is:
a- you have a properly grounded metal pipe (pic related, one example of pipe grounding, green wire is the ground)
b- the pipe is metal all the way from the grounding point all the way to where you want to run a wire to your outlet, for grounding
c- you have proper electric contact between the grounding wire and the pipe.

Unfortunately, the only way to do point b- reliably is a visual inspection. Less then this, you are going on faith. But if you can see the entire length of pipe, you can probably run some solid wire up it and install a properly grounded box.

Point c means taking a buffing wheel or sand paper to the pipe until it is shinny; no paint, no grime, no verdigris. It also means using a proper fitting (like in pic) to create the contact.
