I've looked at this site from time to time and think it's very informative and so I decided to join.
I've just conveerted my LP gas grille to natural gas, and Charmglow said it was impossible, but have some tricky bends and so the solution might be to use copper.
Years ago I put an outdoor gas lamp on a post and was told it would be ok to use copper that was "tinned" inside to offset the problems with the gas/copper problems.
If I can find some here in the desert, I will use it as I'm going through a "maze" of pipes at bad angles 18" below grade or check with the local "experts" for a better solution if possible.

Hello from the California desert!
Check with your natural gas supplier supplier to find out what is acceptable NOW, since materials, standards and codes change. They are usually helpful and free since they want to sell gas.
High desert or low desert? There may be different soil conditions/problems for buried lines and this may be a local situation.
If you are 18" below grade (which is smart) and will probably do more work in the area, do it right the first time, so you can forget about it and go about living in the desert - it is great at twilight and at night in the undeveloped areas.
