QUOTE(andrekua2 @ Mar 18 2016, 12:18 AM) I think never use copper pipe for propane. Copper is a super conductive material plus it is also a very good heat conductor. Most of the time, they used stainless steel pipe with gases. There are cases where they used copper pipe like those compressed air tank in palet but I never seen anyone using copper pipe with propane. Copper pipe for gas delivery have been use for very very long time. Even before you born. I have experience install copper pipe for gas heater from ground floor (gas tank) to upper floor bathroom. And even for kitchen. For restaurant kitchen their jet engine cooker, there use GI pipe. Not SS pipe. For consumer household, Flexible copper pipe or thick copper pipe will do. It can stand the heat and pressure. (Consumer gas pressure is low). 1 of the example is your aircon gas deliver between indoor and outdoor unit. Touch the hot cooper pipe and you know how hot is it. |

SS pipe also conductive, and also heat conductor, SS because of its price. Bending will have problem for SS if not done correctly. For non expose area copper were used, even on gas burner internal. Expose area many uses GI Piping for its strength and price. AC Pipe also use copper, open up rinnai or any gas water heater, internal also copper. Even Instant water heater internal is also copper. |

Just some of my clients insist on getting stainless steel for flammable gas application (we are just a steel trader). |
