Abstract:  
Problem: Worldwide thousands of miles of pipelines in the range of diameters one to three or more meters are existing. The outside surface normally is protected by various kinds of coatings. If the pipe is underground, lifetime protection is necessary. Pipes in the open air might require maintenance, depending, between years or decades. The inside surface, depending on the medium flowing, quite often needs a coating, and e.g. in hydroelectric power station systems, such coatings must be rebuilt after 20 to 40 years of operation of the pipe system.
