Yes there are special precauctions. Typically carbon steel has velocity limits in oxygen service. See CGA publication G-4.4. I believe the most recent version relaxes the velocity limitations for carbon steel in oxygen service at very low pressures. A key for oxygen piping is cleanliness. Meticulous procurement, fabrication, installation, cleaning and inspection are mandatory to remove combustibles and particles from the pipe wall.
