Have any of you tried copper (plumbing) pipe for this?
It's not as readily oxidised as iron, and doesn't spall in the same way; the surface layer of oxide protects the underlying metal in normal conditions.
Its melting point is not as high as iron/steel, but given the cooling effect of the air inside it might work.
(Copper melts at 1084.62°C, 1984.32°F.)

I did use the copper plumbing pipe...this was my first build (I'm about to tear it down and rebuild, correctly, this time!), so I have nothing to compare it against! I needed to replace the copper about every 6-8 weeks during the season. The part right in front of the port would just disintegrate - Oh, also, my batch box is in my greenhouse and I fired it almost every night for about 5 months, maybe 6 months, so the copper saw a lot of heat....

Thanks for reporting back on the copper pipe fail. Someone mentioned it in another thread but had not tried it yet. Maybe they will read this. I bought some titanium heavy foil I am going to make some preheat tubes with(not a pre-port setup). I'm making sure I can easily replace them with some stainless tubing if needed. I will report back next year...lol -Gadget |
