6" clay chimney pipe

randombar

Hi All,

Trying to finish a pizza oven I'm building at the moment and trying to source a chimney pipe for it. Doesn't have to be that long, maybe 18" or so.

I can't find a clay pipe that narrow though 150mm / 6" anywhere in Cork.

Does anyone have any suggestions for me?

Thanks,
Gary

Doesn't really exist anymore? As someone once said to me its too expensive to pay the potters to make them.

18inch is also probably a bit long. iirc most old 6 inch land drain pipes were only a foot long.

Best bet would be a salvage yard and even then 3 or 4 inch will be a more common size, have an old 3 foot long (plus collar) 3 4 inch clay drain here if you are anywhere near Waterford.

That'd do me grand. Waterford is a bit of a trek for me from Cork though.

Salvage yards seem to be dying out from what I can tell, not many around and those I've rang have very little.

Dungarvan?

No problem they have been laying out in the garden for about 20 years.

Why don’t you use metal readily available.

Maybe because it expands a lot more and at a different rate to the rest of the brickwork in the pizza oven.

And a 20 year old pipe designed for excrement movement is a better choice?

Metal would tarnish badly out in the elements and that, I've seen a few online that went funny.

Poor quality stainless perhaps.

Why does it have to be 150 mm.

Standard 9" would be much too big for it. It's a pizza oven so needs to be small enough.

Why not build a nice red brick chimney?
A 12" X 12" (brick and a half) square stack would give you a 4" X 4" chimney.
Same as a 4.5" pipe.
You may have to use lime though.

I was thinking of a brick version all right but was tight for space.

Its a good match for colour too.
