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,

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.

Wrap was [FlyRotary] Re: Exhaust?
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.

I just do not think any sort of exhaust wrap belongs
in an aircraft. It might work just fine - but, if it does
not........., ..but, just my opinion.
