Abstract: The pipe heater manufacturing process comprises a vacuum making process A for introducing a stainless steel pipe into a furnace and evacuating the inside of the furnace, for example, to a pressure of 0.5 Torr, a pipe end sealing process B for brazing and sealing plugs 3 to both ends of the pipe under vacuum and brazing, a process C for forming a lower insulating layer by repeating several times the steps of screen printing and insulating glass material and baking it in a state in which the two ends of the pipe are sealed, and similar formation process D of a heat generating layer and formation process E of an upper insulating layer. With this method, baking in an oxygen-free state inside the pipe makes it possible to obtain the oxidation-free clean state without high-temperature corrosion on the inside of the pipe having the fluid to be heated flowing therein and to manufacture a pipe heater in which a heating response was improved by forming thin heating layer and insulating layer.
