Seeing how you didn’t get any replies, you probably figured out we’re not to concerned with our chimneys

. The vast majority of chimneys around here are exposed (not lined, covered or built-in) black single wall pipe with the crimped insert joints, and a section of Metalbestos or similar insulated Class A pipe for penetrations and close-clearances.
There are variations:
Some people secure the insert joints with screws, but many don’t. Some people attempt to seal joints with the high-temp caulking, but most don’t. Some people (including a few on this forum) use stainless instead of black steel for the single-wall section, which is superior, just more expensive. And some use an air spce instead of insulated Class A for their penetrations. Other than that it’s pretty much all the same.
Like I said, almost all stove pipes here are exposed inside the dwelling. We don’t have very many old masonry chimneys and such like you might. Therefor, if our pipe has a problem we can usually see it and fix it. The only thing we really have to check on is the exterior section, which can get damaged by quakes, ice, birds, wind and trees. You’ll find that most handy Alaskans tend to not overthink things too much. Stove pipes are not complicated.
