Fab tubing for hotside?
I use stainless as you can see, but mid still has lots of good attributes. It at least deserves consideration where some lacks the equipment or skill to work with stainless.
Consider the gas turbo pipes see...superheated carbon dioxide, water, nitrogen, plus some other scarcer stuff like OH, and CO. Corrosion happens much faster the hotter you get as well.
Not trying to stir anything either, just putting out information. I have a mild steel sch40 log and 304 crossoverpipe and downpipe. The log, even being thick *** sch40, has had to be repaired because of cracks and leaks and not to mention looks horrible because of the outside coking and flaking off. The stainless parts look brand new, just goldish in color.
