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.

What Color is used for compressed air pipe?
You can use copper pipe.
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.

How can I effectively repair a copper pipe?
To effectively repair a copper pipe, you can use a pipe cutter to remove the damaged section, clean the ends of the pipe, and then use a soldering torch to join a new piece of copper pipe using solder and flux. Make sure to follow safety precautions and practice proper soldering techniques for a successful repair.
How can I fix a copper pipe?
To fix a copper pipe, you can use a pipe cutter to remove the damaged section, clean the ends of the pipe, and then solder a new piece of copper pipe in place using a propane torch and solder. Be sure to follow proper safety precautions and techniques when working with a torch.
How can I effectively repair a copper water pipe?
To effectively repair a copper water pipe, you can use a pipe cutter to remove the damaged section, clean the ends of the pipe, and then use a compression fitting or soldering technique to attach a new piece of pipe. Make sure to follow safety precautions and use the appropriate tools for the job.
How do you connect copper propane pipe and shutoff valve?
To connect a copper propane pipe to a shutoff valve, you will need to use a threaded fitting that matches the size and type of the pipe and valve. Apply pipe dope or Teflon tape to the threads before connecting them. Tighten the fitting securely using a wrench or pliers to create a leak-proof connection.

How to cut copper pipe effectively and safely?
To cut copper pipe effectively and safely, use a pipe cutter designed for copper pipes. Measure and mark the pipe where you want to cut it, then place the cutter around the pipe and tighten it. Rotate the cutter around the pipe until it cuts through. Wear safety goggles and gloves to protect yourself from sharp edges.
