Through the setting that junction boxes 6 are provided on both the upper closed shell 3 and the lower closed shell 2, it is convenient for the staff to carry out maintenance and repair. Only the damaged parts need to be disassembled separately, which does not affect the heating work of other devices and reduces the maintenance and repair costs.

[0020] Furthermore, strip-shaped flanges 10 for connecting the two are symmetrically provided on the left and right sides of the lower closed shell 2 and the upper closed shell 3.

Next, other far-infrared heating devices are sleeved on the pipeline 1 one by one in the above manner, and the adjacent far-infrared heating devices are connected by the semi-installed flange 9. After all the far-infrared heating devices are installed, the electric furnace wire 11 is started to heat the substance in the pipeline 1. The utility model has a beautiful appearance, a simple structure, is convenient for disassembly, installation and maintenance, and the working temperature reaches 900 °C, which can meet the needs of the user for heat preservation and heating of the pipeline 1, greatly improving the applicability.
