A combined heating and cooling device for coating the inner walls of pipes may include heating areas and cooling areas. This device can be guided along the pipe to be coated, wherein a fluid containing the coating active agent is supplied to the interior of the pipe. The combined heating and cooling treatment for the pipe supports the process of coating formation. The cooling process is subject to a desired profile by the use of the cooling area and is not determined by chance.
