Stainless steel inverse spike

[Odissey]

Good day.

I want to make a pipe with a invers spike from a steel tube. The tube of stainless steel. Somewhere I saw something like that. I did not find anything on the forum.
Is this an option? Did this lead to an excessive concentration of moisture in the smoke duct?
There are tubes with a cooler, the role of which is performed by a steel spiral inserted into the smoke channel. But here the mass of metal will be significantly greater.
In this case, I fear the trick.

There are some who have mastered this. I am not one of them. Outside of reinforcing a super thin, long shank, I don't see the benefit such that it warrants all the fuss.

For me, new experience comes first. Everything turned out to be far from simple. The second day is already tormented. The stainless steel tube was not perfectly round (I am an idiot, it could not be different). The difference in diameter in one section is 6.1 mm, in the perpendicular 6.05 mm. The tube is barrel-shaped. If there was a lathe, I would take it and remove the excess metal to the desired diameter. And now I have to look for a way how to remove this barrel shape with my hands.

George Dibos maintains that the stainless tube will not make any difference in condensation. Scotty Piersel and others use tubes to reinforce pencil shanks and in the construction of bamboo adornments and shank extensions. I have several of these pipes and notice no extra condensation.
I am not sure if naked SS tubes will work as well because of the lack of insulating effect of briar or bamboo.
For your deformed tube, I would probably try to get a better piece.

I use 3/16” tube which gives an ID of approximately 5/32”- the inside diameter of my airways in both the stems and stummels. The cut ends should be carefully deburred to prevent an accumulation of pipe cleaner fuzz and gunk.

The stainless reverse tenon makes a very thin shank possible by removing the leverage of a partially inserted tenon from the briar end and placing it in the vulcanite end.

Thanks to all!
