Hi ; In my opinion you have had an overtemp situation ; IE: hot start or tailcone fire.
Since you said the integrity of the tailcone is still there you could probably fly it with not problem but will most likely have a reduced thrust rating.
I would also suggest monitoring it after every flight or run while ordering a new tailcone.
Good luck.
I with you agree!
I by a trade - the metallurgist. And I often face a problem Chinese and Indian (heat resisting a steel), a problem in chemical structure of metal! In these countries apply in "a chrome" place apply "manganese" and there are problems with pipes! Is a basic problem! Who-be did the chemical analysis of the Chinese pipes?????? I am assured - was not present!
The second problem this a thickness of a material...
And the third problem is a spot welding! For models I do pipes on new technology, an integral welded seam of laser welding! It is very strong and reliable!
And for the information: I apply a military material which is easier usual on 10 %!
If qualitative and good pipes are necessary to you, please contact with me!
P.S It is impossible to use this pipe long, in the future your pipe will burn through! It is impossible!!!!!!!! I speak to you as the expert!
