Interesting about the years of service some get on their pipe. I usually get the cheap local Lowes pipe and change it every few years just to be safe. I only have about 8 foot of single wall and 2 adjustable 90s shaped into 45s ,the rest is triple wall that runs up the inside walls of the house. . I never tried a high quality single wall .

It was a live-and-learn experience for me with chimney pipes.

My first black pipe from Home Depot lasted a whopping 7 months, before it disintegrated to nothing when I tried to touch it lightly ....

Then, I replaced it with 304 stainless. Thinking it would be impervious, I left fly ash in it all summer long, and discovered it perforated all over with little pinholes of various sizes - some bigger than others.

From that point forward, I thoroughly clean the pipe at the end of the season, and store it in our air conditioned living space. Will never leave a pipe in my basement again. That pipe lasted me another 4 years without any further damage until I sold it along with my Mark III, after hooking up Jim's stoker boiler.

For the stoker, I bought black pipe from ... well, I can;t remember! I just had to look up my boiler install thread, and found out it's a Ventis 22 gauge pipe. Needed three 90°s, & 2 straights. Been taking that upstairs from day one. On it's 3rd season now, and not even surface rust on the outside.

Here's a few pics of the black pipe from '05, and the stainless pipe from '09:

Most people do not need a row boat to navigate their basement.

I got my pipe from one of the box stores (I don't remember which, probably HD) I'm on the second year but I should have cleaned it better after last year.
I was wondering though since most times the flue pipe temp stays under 400*, if any one may have tried painting the inside with a high heat high quality paint, like the good stuff for headers, or maybe a ceramic paint?

Yes, it was mentioned in another thread to paint the inside of the pipe.
