The study of the temperature regime of glass coating deposition on the inner surface of the heat exchanger tube has been carried out. The choice of the temperature regime for coating the pipe depends on the physical and mechanical properties, geometric dimensions and temperature distribution at any points of the coating and the metal part of the heat exchange pipe. The regularities of the change in the temperature field of the deposition of glass coatings on the inner surface of the pipe depending on the heating time of the electric heating furnace are obtained theoretically. It was found that the temperature when applying a glass coating on the inner surface of the pipe mainly depends on the brand and thickness of the glass sealed rod.
