Yes, you absolutely may use copper pipe for Oxygen service. There are, however, several things that must be taken in to consideration.
First of all, any piping that will carry Oxygen MUST be cleaned in accordance with CGA G-4.1. If there is any oil / hydrocarbon residue in the pipe and pressurized oxygen hits it with any force there is a high probability that the oil may ignite. You should purchase tubing and fittings that are cleaned and bagged for Oxygen service.
Second, you need to keep in mind that copper tubing is for relatively low pressures. The pressure rating is also dependent upon the method used to join the copper.
If the copper is intended for cryogenic oxygen service, a high silver content brazing alloy should be used. Also, whenever brazing you should have a constant purge of dry nitrogen flowing through the pipe - this will prevent oxidation / scale inside the pipe.
After assembly you should pressurize the system with Nitrogen and use a bubbling leak detector that is OXYGEN SAFE to check for leaks. Whatever method is used to join the pipe, you must be certain that there is no contamination (oil, flux, etc) inside the pipe before the system is pressurized with Oxygen.

You can use copper pipe.
How do you connect copper propane pipe and shutoff valve?
Flare copper pipe and use a flared shutoff valve. If valve isn't flared, use an adapter fitting between copper flared pipe and valve.
Can you use soldering copper pipe fittings for gas?
It is not a good idea to use copper pipe with natural gas as any sulphur compounds in the gas can cause an oxide to form in the copper pipe. Often copper is used with propane. In these instances, soft copper tubing is usually used with compression fittings. The tools required are, pipe cutter and 2 wrenches.
What is a sweat inlet?
It is probably referring to the type of fitting. A fitting that is soldered to a copper pipe. It is called sweating when you use solder and a torch to connect copper pipe together or attach fittings to copper pipe.
How do you know if you have copper or steel drinking water pipes?
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
How do you repair a pinhole in copper pipe?
Use a lead-free silver solder. It is the only thing that can handle the pressure and bond with the copper pipe.

Can you use cast iron clamps on copper pipe?
Not directly without some type of sleeving or protection between them. They are dissimilar metals and it will create electrolysis which will severely impair the copper pipe and create holes in the copper in the future.
