Electric heating tape can be used for low temperature occasions

　　In industrial production and civil facilities, low-temperature environments often pose many challenges, especially when temperatures drop below freezing, with problems such as frozen pipes, equipment shutdowns and material embrittlement ensuing. Electric heating cables, as an efficient temperature maintenance solution, show unique advantages in low temperature situations.

　　From the polar scientific research station to the alpine region oil pipeline, from the frozen warehouse to the winter outdoor facilities, electric accompanied by the tropical system through the accurate temperature control, effectively solved the low temperature environment of the various technical problems, safeguard the normal operation of equipment and process stability.

　　Electricity accompanies the tropical belt in the low temperature environment application firstly embodies in the antifreeze protection aspect. When the ambient temperature is lower than zero degree, water pipe, fire pipe, process pipe in the static liquid is very easy to freeze and expand, resulting in pipe rupture. The self-limiting temperature electric accompanying tropical belt can automatically adjust the heating power according to the ambient temperature, and start in time when the cold comes to maintain the pipeline temperature in the safe range. Compared with the traditional way of continuous heating, this self-adaptive characteristic greatly reduces the energy consumption. In the sewage treatment plant in the alpine area, the electric accompanied by the tropical belt prevents the freezing of the treatment equipment and the pipeline, and ensures the normal operation of the livelihood facilities in the severe winter season.

　　In addition to the conventional anti-freezing, electricity accompanies the tropical belt in the low temperature process field also has the important application. Certain chemical processes need to be carried out in a specific low temperature range, such as liquefied natural gas (LNG) pipeline cooling accompanied by heat. In this case, the role of electric accompanied by the heat tape is to compensate for the loss of cold, to prevent the outside heat into the medium temperature rise. Special low-temperature type electric accompanying heat tape is made of cold-resistant materials, even at extremely low temperatures still maintains flexibility, will not be brittle and cracked. In the semiconductor manufacturing industry, the process cooling water pipe needs to be maintained in the temperature close to the freezing point, electric accompanied by tropical and refrigeration system work together, accurate control of temperature fluctuation is not more than ± 0.5 ℃, to meet the requirements of precision manufacturing. This kind of fine temperature control ability, make the electricity accompanies the heat tape to become the low temperature process indispensable auxiliary equipment.

　　Electric accompanied by the reliability of the tropical in the low temperature environment from its special design and material selection. The outer sheath of the cold-resistant electric accompanying heat tape usually adopts improved polyolefin or fluorine plastic, and these materials still maintain good flexibility and insulating property in low temperature. The heat generating element is specially treated to ensure that it will not be damaged by a sudden increase in current when starting at low temperatures. High-end electric heating cables for polar use are also equipped with multi-layer insulation structure and waterproof design to prevent the melting of snow and ice from infiltrating and affecting the performance. In terms of installation, low-temperature environments tend to use higher density winding with thicker insulation to cope with the challenge of greater temperature differences. These targeted designs enable electric heating cable systems to operate stably for many years in extreme environments such as the Arctic and Antarctic.

　　The introduction of intelligent control technology further enhances the performance of electric heat tracing in low temperature situations. Modern electric heat tracing system is usually equipped with temperature sensors and intelligent controllers, real-time monitoring of the temperature change of the object to be accompanied by heat, according to the actual demand for dynamic adjustment of heating power. This kind of on-demand heating mode avoids energy waste, especially suitable for the area with big temperature difference between day and night. In the remote monitoring aspect, the Internet of things technology makes the operator can grasp the electric accompanied by the tropical working state which is distributed in the wide area at any time, discover and deal with the abnormal situation in time.

　　Along with the world to the extreme environment development depth, electric accompanied by the tropical in the low temperature occasions of the application of the prospect is more and more broad. The application of new composite material reduces the threshold of low temperature start of electric accompanied by the heat; The improvement of self-diagnostic function improves the reliability of the system; The integration of renewable energy makes the electric accompanied by the heat of the remote area possible. In China's ‘Silk Road on Ice’ in the construction of the Arctic shipping lanes, electric heat tracing technology for port facilities, liquefied natural gas station and other key nodes to provide a reliable frost protection.

　　In the future, with the advancement of climate change and polar development, electric trace heating belt will play an important role in more low-temperature occasions, and provide technical support for human activities in the cold environment. From daily life to national engineering, this seemingly simple heating technology is creating irreplaceable value in low temperature environment.
