What's not to like? This is easy on straight sections but not so where the
pipe curves. Would be really tough to shield my exhaust like this. I havent
tested anything like this but suspect that it is not as effective an insulator
as the wrap or some other sort of barrier (like the Zetex or Fiberfrax).
My exhaust is made of .060 mandrel bent 321 stainless and coated in and out
with a 2000 degree ceramic coating. So not sure how relavent the comparisons to
wrapped mild steel are. I agree with the inspection related comments. But would
like to hear from anyone who has used the tape in an aircraft install where the
high heat is constant, on a comparable exhaust (i.e. 321 stainless).
The real issue here is my cowl is close. And after all the work to make it
the prospect of burning it up isnt an option. Lesson learned is to make sure ALL
engine work including fabrication of exhaust is complete before making a cowl.
But that ship has sailed so now I'm looking at ways to recover. The simple
shields that Lynn proposed will leave too many gaps and too much potential for
cooking the cowl.
The Zetex looks like a possible answer if I can find a source other than
the manufacturer that has small quantities available.
Anybody have any experience with Fiberfrax (Aircraft Spruce sells it;
claims its good to 2200 degrees)?

I think that's what the Doctor ordered, Lynn
Simple, effective, light weight, permits inspection,
relatively inexpensive, can be easily removed, does not cause deterioration of
the tubing, can be done in home work shop.

OK, How about this.
A shield in .015" stainless. The tabs can be bent inboard to take up
less space. The air gap can be as little as 1/2". Only needed on the side
where some protection is required. Very light. Can be wired on instead of
hose clamps. Removable for tubing inspection.
