Alternative to copper tubing for lpg

Black iron. But you'll need to rent a threader and cutter.

I used black pipe for a similar project. Cutting/threading is easy when using those sizes.

good point, and especially if you think you'll ever need it again. I bought my rigid threader on ebay for about $100 with 5 dies, and 2 cutters.

I wouldn't buy a dog turd from HF.

But, they are on sale this week..... with internet coupon.

My local hardware store sells the pipe and also cuts and threads it.

Yes, you are mistaken.

I still don't see it used in Florida. LPG is piped with plastic underground and copper inside or galvanized outside above ground on the low pressure side of the regulator.

galvanized is strictly not recommended. It's not against code, but it can 'flake' and plug orifices.

Some local codes, at least, do prohibit galvanized...

Recently there have been some studies that indicate that usage isn't as much an issue as was one time thought (zinc reaction w/ trace contaminants) but other data I've seen indicate that w/ more imported gas and domestic supplies becoming more limited that those issues may becoming more significant again...

Overall, I'd recommend against it (galvanized, that is) simply on basis of long-time precedent irregardless of local code on the issue for either NG or LP or LNG.

I don't suppose pipe rusts in your area

Of course it does, but it's less of an issue than galvanized in contact w/ certain contaminants in gas, hence the historic proscription. I've heard the flaking and orifice theory before as well, but never found it codified for that specific reason (that's only saying I'm unaware of where to find it written, not that it hasn't been).

And, of course, the previous recommendation was _only_ wrt to black over galvanized, specifically, not any other possible alternatives.

Here is what I used for mine..its a pale pastel green pipe-coating..I bought it in threaded lengths from a local plumbimg supply dealer. Local codes also insisted on a black tape-wrap for the underground portion.

The gas companies in SW Fla seem to have overcome those problems. In fact the factory pipe in my pool heater is galvanized.

I'm suprised no one mentioned CSST (corrugated Stainless Steel Tubing). With the high price of copper, it's worth looking into.

I said it was historic and that there were some recent reports indicating it was less of a problem than some earlier data had implied. As with anything else, new information eventually supercedes older.

Some of us old fogey's stay w/ what we were taught...I doubt I'll ever get over the rule. :)

It could be as simple as they improved the galvanizing process so they don't flake anymore but you do put a trap in a gas line right before the appliance anyway (that dead end on the last "T")
