How to make hollow ceramic pipe

[Kaoru]

We are supplier of thermal spraying for cermic coating.
and try to ceramic roll

To make a hollow ceramic pipe by water plasma spraying on steel pipe with 1300℃, then after cooling down, how can I pull out a ceramic portion only from steel pipe??

I do not know how to pull out a roll portion.
Please advise me if there is a good way (ex. kind of steel ? or paint some chemical solvent ? or sandwitch something on steel pipe?...)

Thank you for your attention

I would suggest using a graphite pipe to apply ceramic then you can melt the graphite.

Thank you very much for your suggestion.
To melt graphite, chemically by using solvent, or electrically by using
spark erosion??

Hey Guys me Mark.Well i think that If you have access a kiln, you can create your own ceramic pipe.And also you can use it for tobacco.This is a hundreds of years old art and in some nations professional pipe creators still create these pipe joints by hand.Thanks!!
