EXPLOSION-PROOF SELF-LIMITING TEMPERATURE ELECTRIC HEAT TRACING

Self-limiting temperature electric tracing tropical (also known as: automatic temperature electric tropical, self-regulating heat tracing cable) can automatically control its own temperature, can quickly warm up when starting, when the heating temperature reaches a certain value, it will stop working on its own, if the temperature is lower than this value, it will automatically warm up, so repeat; The product is widely used in petroleum, chemical, iron and steel, electric power and other industrial enterprises pipeline, storage tank heat tracing insulation, anticoagulation, antifreeze. The e cable is suitable for common areas, dangerous areas and corrosion areas.
Features of Electric Heat Tracing
1. Electric heat tracing converts electric energy into heat, to compensate the lost heat and maintain the process temperature.
2. Electric heat tracing can produce uniform heat along the whole surface of the pipeline and tank. While electric heaters produce heat on one single point or only a small area, which will cost much more electric energy than electric heat tracing system.
3. Temperature of electric heat tracing can be controlled to a much narrower range than hot water’s. Moreover, it can stably produce heat and has long term performance.
4. Installation of electric heat tracing is quite simple. It can keep the heat uniform and temperature can be controlled by remote operation or auto regulation. Besides, it has the characteristic of explosion-proof, fire proof and anticorrosion.
5. Compared with steam heat tracing, electric heat tracing has higher heat efficiency and remarkable energy-saving effect.
6. Design of electric heat tracing is easy. Its installation is simple and quick. In addition, it has characteristics of easy operation and almost free maintenance.

Typical Applications of Electric Heat Tracing
Electric heat tracing applications can be widely used in petroleum, chemical industry, electric power, metallurgy, mechanism, and medical industry. Solutions can be provided for freeze protection, temperature maintenance, anti-condensation, etc. The specific applications are as follows：
1. Temperature maintenance, anti-condensation and anti-drag of the oil pipeline.
2. Temperature maintenance, heat tracing of chemical pipeline, tank, instruments.
3. Temperature maintenance of fuel pipeline and freeze protection of water-pipe in power plant.
4. Temperature maintenance of wellhead as well as other kinds of tubing.
5. Temperature maintenance of pipeline requiring accurate process temperature.
6.Heat tracing, anti-condensation and anti-drag of the pipeline, valve, pump and vessel, in which the medium is liquescent, easily solidified and crystallized. For example, gas, liquefied gas, chlorine gas, raw oil
and cooking oil.
Snow prevention of pipe, tank, etc.
Using in drying system or shorting process period.
