Hello, new guy here.

I've got a wood burning furnace in the cellar which seems to just eat the single wall 6 inch pipe that connects it to the chimney. I have to replace it at least yearly. I'd like to get some stainless pipe, just like the black only SS. I only need 2 lengths and an adjustable elbow, but I can't find any! I managed to find an elbow online, but it's basically made for duravent. Anyone know where I can get any plain old snap together SS stovepipe?

Thanks.
 
Snap pipe doesn't last. It's too light gauge and shouldn't be used for stove pipe. Durablack pipe is 24 ga, Selkirk Saf-T pipe is 22ga. Either will last much longer. Or you could use Selkirk Saf-T rigid liner which is stainless.

Well the snap pipe is crap but having it only last one year means you have a lot of moisture going through the pipe.
 
That Selkirk liner seems like a good idea. Big difference between 304 and 316? How does it match up with conventional 6 inch?
 
The rigid liner pipe can have variances from standard pipe. I have seen elbows at the hardware stores along with the pipe. Definitely get all one kind of pipe, as they all seem to have a bit of difference and get the heaviest gage you can. You should not be burning out pipes every year.... At least not in my experience.
 
Thanks for the replies, Heat fab seems the way to go, and I might as well spend the extra and get the 316. For some reason my burning environment seems very corrosive. I've got a flexible liner in the chimney terminating with a take -off type SS tee in the basement, and the clamp on the T has failed also.

Does anyone know if a Heat Fab T would slide onto flexible liner pipe?
 
Give them a call to see if a transition piece is needed.

The corrosion issue is a bit odd. What are you burning normally?
 
Yeah the corrosion is kinda weird. I have seen some when I was a kid on old stoves with black pipe that had been burned for years. I do not understand this situation, seems odd to need a new pipe after a year or two.
 
Could it be condensation forming from the summer heat going down the chimney into the basement, or do you burn any coal? I would plug the flue once the season is over and see if things are better. Just make sure to have a note handy as a reminder. Also make sure everything is clean at the end of the burning season. I've seen horrible creosote from the old furnace, and even then the flue pipe lasted for years.
