The study investigates the heating process of the polymeric coating-pipeline metal system under the influence of microwave electromagnetic field. We developed a mathematical model of thermal processes at microwave processing of multilayer systems with non-uniform structure and properties. Moreover, we developed and substantiated the operating parameters of heat treatment technology for pipeline anticorrosive polymeric coating by microwave heating allowing for improvement of physical and mechanical properties of the coating. Furthermore, we developed a mobile microwave device for processing the coated pipeline internal surface. The study experimentally tests the effect the microwave processing modes have on features of thermal processes progress in the polymeric coating-pipeline metal system, as well as its effect on development of coating high serviceability. Finally, we examined the characteristics and properties of coatings in the wide range of microwave power influence, and determined temperature dependences of system heating on time and microwave power influence. By experiment we established the 3.5 degrees temperature rise in the pair coating-primer that promotes stronger adherence with pipeline metal.
