With the development of science and technology, the electric heating trace cable has been gradually applied to all walks of life, people will according to different occasions choose different heating cable, and electric heating trace cable in the process of its use play a different role. For example, the catalyst pipeline in the use of electric heating trace cable, mainly or anti-freezing heat preservation role. Because the catalyst temperature is relatively low, generally not more than 100 degrees Celsius, so in the low temperature environment is easy to freeze phenomenon, if there is no appropriate insulation measures, catalyst by the adverse effects. At this time accompanies the heat tape in which plays a great role, since the temperature limit  electric heating cable as a kind of can precisely adjust the temperature, the heat preservation effect good electric accompanies the heat product, can according to oneself to regulate the heat, causes the catalyst pipeline to always keep the stable temperature, more safety and energy saving.

 　　Electric heating cable working principle: is through the electric accompanies the heat produced by the heat, is the oil and gas pipeline and the liquid inside the container in the external ambient temperature is low when maintains in the required working temperature, so as to ensure that conveys the fluid does not freeze, the pipeline does not block the phenomenon. The electric heating cable pipe insulation technology has the design workload is small, the construction is convenient and simple, simple and easy to understand, can according to the instruction manual to find the electrician to install, is very suitable for the pipeline antifreeze heat preservation.
