There's no problem with running natural gas in copper. It's run that
way often in industrial and laboratory installations.

Hey EL , Plain copper tubing it never used on any natural gas transfer
tubing lines at all unless they are lined with some type of coating like AL.
or epoxie coating to prevent the chemical reactions to make the Sulfur drop
out of the natural gas and only if it has any left in it when it is used.
Also you have copper oxide to deal with in the burning equipment in these so
call lab burnering equipment your speaking about. If you check you will find
they are lined with a coating and not regular copper tubing lines. Now I
have been told by the manufactors of propane equipment that regular copper
can be used because propane is not suppose to react with the plain copper.

So, plain copper tubing is never used on natural gas lines in industry or
laboratory installations unless they are have a liner coating in them.
