きる。 In the pipe heater described above, the inside diameter of the flow path 9 through which the fluid of the heating elements 1, 1, . . . passes can be covered with a synthetic resin or an inorganic insulating material. In particular, when used for preheating or keeping warm to prevent freezing or dew condensation in a liquid or gas piping system of chemical equipment, it is recommended to use it as a measure against electrical leakage caused by the fluid in the pipes or the conditions of use. In addition to heating pure water used for cleaning semiconductor wafers, medical analysis, and petrochemical solvents, this pipe heater can also be used to preheat or keep warm liquids and gases in chemical equipment, and to heat and dry air and inert gases. Alternatively, it can also be used to preheat fuel oil, gas, etc. In particular, fluids can be heated with a simple power supply such as a battery, so automobile fuel,
Can be used for air supply line. By setting the number of heaters according to the heating temperature of each fluid, the above-mentioned pipe heater can be used for general purposes as appropriate. Furthermore, since no elution of ions occurs with heat generation, no impurities are mixed in, and continuous heating of the fluid can be performed simply by applying voltage to the heating element.
Furthermore, since silicon carbide has good thermal conductivity, this heat generation acts to smoothly raise the temperature of the fluid, and the temperature can be raised to an extremely high temperature.
