Abstract (en)

[origin: DE102007030591B3] The method involves introducing a fluid containing a coating material into a pipe (11). The pipe is locally attached with a movable heater (23) based on temperature required for forming a coating, until a layer forming process is locally completed. The heater is moved as long as a layer is formed. A residual fluid is removed from the pipe, and local cooling of the pipe is supported according to the layer formation by a movable cooler (24). A precursor for ceramics is contained in the fluid. An independent claim is also included for a combined heating and cooling device for a pipe.
