I used .120" wall mild steel tubing for primaty headers. I wrapped them with
heat tape. three weekends after I added the heat tape I notices a clump of the
tape missing. I crushed the tube with my hand. It was like thinwall glass.

Then the tube bender made up son 90s for me from .140" wall stuff he had on
hand.

I did not wrap them and have a blast tube blowing on them no problem in 6
years.

Thick wall stainless sounds real good to me.
