How to prevent electric heating band from being burnt by high temperature

Electric tracing band is a new type of thermal insulation material, which has been widely used in the antifreeze and thermal insulation of pipelines, transportation and other equipment. The power of the electric tracing band is also different from its model and temperature resistance grade. If the temperature exceeds the bearing temperature of the electric heat tracing tape, its function and structure will be affected. At this time, it can not only prevent the pipeline from freezing and heat preservation, but also may be damaged and need to be replaced. How to prevent the heating band from being burnt by high temperature?
When the electric tracing band is used for tracing the instrument pipe with high temperature and high pressure medium, the surface temperature of the instrument pipe will rise sharply when the pipe is flushed, exceeding the bearing temperature of the electric tracing band, which is easy to cause the electric tracing band to burn out. Do not touch high-temperature objects, and do not splash high-temperature welding slag onto the surface of the electric tracing band. If high pressure steam purging is required during the process operation of heat tracing pipes and equipment, the pipes can be flushed and removed before installing the electric tracing band, and then the electric tracing band can be placed to avoid scalding the belt at high temperature. Therefore, the electric heat tracing manufacturer once again said that in order to prevent the surface temperature of the electric heat tracing band from being too high when placed, the surface of the instrument tube is usually covered with a thin layer of thermal insulation material, so that the instrument tube can be separated from the electric heat tracing band; Or when installing the electric tracing band, connect it with the surface of the instrument pipe at a certain distance to avoid direct contact between the electric tracing band and the high temperature when flushing the pipe.
