Rusting Black Stove Pipe

All Good Advice......... I pull my pipe at shut down. Rinse with hose, Spray with baking soda/water mix, Let dry in hot sun, Store till fall.

I have never removed mine...still seems solid after 6 years. No visible rust. Must depend on the conditions?

I only get 2 or 3 years out of black pipe before the rusty areas start to feel tender when I press with my thumb.
Chimney cap I had to replace after about 8 years -- looking up from the bottom I could see lots of pinhole stars like in the planetarium, and when I hit it with the cleaning brush it fell apart.

Black pipe in my moist basement lasts 2-3 months after shutdown. It will be swiss cheese in that timeframe.

304 SS pipe lasted almost a year in the same conditions, but developed pinholes due to not cleaning the flyash out at the end of the season. With regular cleaning, I got 6 years out of the pipe, and sold it with the stove when I installed the stoker boiler.

All depends on humidity levels. More humid = more / faster rust. Mine is an extreme.

Remember my stainless steel Hilcoil coils? Turned to this in just 4 months:

Dam Smitty! Time to either do something with that swamp basement or just abandon it.

stoker boiler in the shop.

Rberq, you pretty much hit the nail on the head there!

Yeah, in a perfect world I'd have the space, time, and money to move the thing. Ain't happening in this lifetime. I can barely fit a couple push mowers in the barn right now.

Had big plans for a slab / tent project this year. Forgot that stuff costs money too. ALOT of it.

is there a brand of black stove pipe that is best? best places to buy the stove pipe?
when I got the chubby, I had a professional company install it due to having to run up through the ceiling and out the roof.

I get my stovepipe from a local HVAC supply house. It is a heavier grade commercial product, unlike the box and harware stores and is reasonably priced.

I have always professed, that burning a tad of wood at the end of the season anoints the stove pipe & chimney with a coating of creosote; thus reducing the oxidizing effects of coal. Although I have a masonry chimney this will be my 4th year will the same stovepipe. Still no signs of deterioration. Just a redneck experiment to see if my theory has any merit.

I checked out this link, and can't use this stuff. It's advertised for "wood" stoves.

Actually, years ago, I bought a dura-vent kit from HD that's was a leftover special, or something like that. Marked down 75%. It's the kit that goes through the roof and ceiling. (flashing, thimbles, cap, "1" section of 3' double wall pipe, ect.) Thinking about installing it soon, so as to maybe have another chimney for another stove. Don't want to pay full price for the rest of it tho.

I like heavy duty galvanized pipe, but it causes some people to twitch when they see it on a stoker boiler (even though the stack temperature is lower than many oil boilers).

I've used galvanized but don't anymore. The manufacturer's recommend black pipe on solid fuel installs for a reason.

Yes, because "solid fuels" include wood.
