Now I have burnt seven years on a Bixby venting system almost always a blend or straight corn but taking great care of the venting after season. What is the lifespan pellet only users getting from thier venting?
Venting lifespan?

Lifespan probably varies depending on a few factors. Such as.... Venting material, what you are burning, and how much you burn per year.
Hence the ? was how long for pellet only to narrow the field down some. Someone usually chimes in about how burning corn will shorten lifespan of venting but search here yielded next to nothing on life spans of venting. Trying to come up with some cost basis of burning corn vs pellet. with corn being around $140 to 150 a ton verse $200 ton pellets. Going out on a limb but average fuel use is over 3 tons with the stove being used as a primary heater. Maybe have to setup a survey of tons per year and how long venting has been installed.
My flex king pro has a lifetime warranty on it for one replacement. I have heard that you should use venting made out of at least 316TI if you burn or mix corn through a multi fuel stove.

Doesn't answer your question exactly but my Selkirk DT pellet has a 15 year warranty. Inner pipe is 304 stainless.

I would think the short pole would be whatever is used to seal the pipe joints not the pipes themselves. Although I suppose annealing could occur although Im not sure the pipe gets hot enough for that. The warranty is pretty useless it just gives a warm thump in your pants when you buy it.
I've noticed the venting exposed to the outside elements is the piece that catches the brunt of the ill effects of combustion. Selkirks DT has both inner and outer pipe of a stainless. But at a cost of $50 bucks a foot?
