Explanation of electric heating tape

　　The electric accompanying heat tape is a kind of heating equipment which utilizes the electric energy to generate heat, it can transform the electric energy into heat energy, and heat and keep warm to the pipeline, container and so on. The electric accompanying heat tape has the advantages of even heating, accurate temperature control, easy installation, long service life, etc. It is widely used in petroleum, chemical industry, electric power, aerospace and other fields.

　　First, the working principle of electric heating tape

　　Electric heating tape is composed of two parallel metal wires and a heat generator in the center. The heat generator is usually made of conductive plastic or metal alloy, which has good electrical conductivity and thermal conductivity. When the electric current passes through the heat generator, the heat generator converts the electric energy into heat energy, which makes the metal wires heat up. The metal wire transfers the heat energy to the pipe or container to maintain a certain temperature.

　　Second, the advantages of electric heating tape

　　1. Heating uniformity: electric heating tape heating body is made of conductive plastic or metal alloy, heating uniformity, there will be no localized overheating or overcooling.

　　2. Accurate temperature control: the electric heating tape can be accurately controlled by the temperature controller, so that the pipeline or container stays within the set temperature range.

　　3. Simple installation: electric accompanied by tropical installation is simple, do not need professional installation personnel, only need to electric accompanied by tropical winding in the pipeline or container, and connect the power supply can be.

　　4. Long service life: electric heating tape is made of high-quality materials with good wear-resistant, corrosion-resistant, aging-resistant performance, long service life.

　　Third, the classification of electric heat tape

　　1. Self-limiting electric accompanying heat: Self-limiting electric accompanying heat is a kind of electric accompanying heat which can adjust the heating temperature automatically. Its heating body is made of conductive plastic, when the temperature rises, the resistance of the heating body will increase, the current will be reduced, the heating temperature will be reduced; when the temperature is lowered, the resistance of the heating body will be reduced, the current will be increased, the heating temperature will rise. The self-limiting temperature electric accompanies the tropical belt has the heating temperature uniformity, the temperature control accuracy, the installation is simple and so on the advantage, applies to the pipeline, the container and so on the heat preservation.

　　2. Constant power electric accompanying heat tape: Constant power electric accompanying heat tape is a kind of electric accompanying heat tape with constant heating power. Its heating body is made of metal alloy, the heating power is not affected by the temperature. Constant power electric accompanies the tropical tape has the heating power, the heating temperature is high, the service life is long and so on the advantage, applies to the high temperature, the high pressure, the large caliber pipeline and so on the heat preservation.

　　3. Mineral insulated electric accompanying heat tape: Mineral insulated electric accompanying heat tape is a kind of electric accompanying heat tape which adopts mineral insulating material as insulating layer. It has the advantages of waterproof, moisture-proof, corrosion-resistant, high temperature-resistant, etc. It is suitable for the heat preservation under the bad environment of moisture, corrosion, high temperature and so on.

　　Fourth, the electric accompanied by the application field of tropical

　　Electricity accompanies the heat tape is widely used in petroleum, chemical industry, electric power, aerospace and other fields. In the petroleum industry, the electricity accompanies the tropical heat can be used for the oil pipeline, the oil storage tank and so on the heat preservation; In the chemical industry, the electricity accompanies the tropical heat can be used for the chemical pipeline, the reaction kettle and so on the heat preservation; In the electric power industry, the electricity accompanies the tropical heat can be used for the power plant steam pipeline, the heat preservation pipeline and so on the heat preservation; In the aerospace industry, the electricity accompanies the tropical heat can be used for the spacecraft, the heat preservation of the satellite and so on.

　　V. Selection and installation of electric heating tape

　　In the selection of electric accompanied by tropical, need to consider the pipe or container material, size, temperature requirements, environmental conditions and other factors. At the same time, also need according to the actual situation to choose the right type and specification of electric accompanied by tropical. When installing the electric accompanying heat tape, need to pay attention to the following points:

　　The electric accompanying tropical tape should be wrapped around the surface of the pipe or container, and there should be no cross or overlap.

　　The ends of the electric accompanying tropical should leave a certain amount of margin, so that in the pipe or container expansion or contraction can be free to expand and contract.

　　Electricity accompanies the installation of tropical should avoid mechanical damage, such as cutting, impact and so on.

　　The power supply of electric heating tape should be reliably grounded to prevent leakage of electricity.

　　Six, electric accompanied by tropical maintenance and maintenance

　　In order to ensure the normal operation and service life of the electric accompanied by tropical, need to carry out maintenance and maintenance on a regular basis. Specifically, can take the following measures:

　　Regularly check the electric accompanied by tropical heat and insulation, such as found abnormal should be dealt with in time.

　　Regularly clean up the dirt and sundries on the surface of electric accompanied by tropical, in order to ensure its heat dissipation effect.

　　Avoid electric accompanied by tropical by mechanical damage, such as cutting, impact, etc..

　　Avoid electric accompanied by tropical by chemical corrosion, such as acid, alkali and so on.

　　Regularly insulate the electric accompanying tropical insulation test to ensure its insulation performance.

　　Electric accompanied by heat tape has the advantages of even heating, accurate temperature control, easy installation, long service life, etc. It is widely used in petroleum, chemical industry, electric power, aerospace and other fields. When choosing and installing electric accompanied by the heat tape, need to consider the material of the pipeline or container, size, temperature requirements, environmental conditions and other factors. At the same time, it is also necessary to maintain and repair it regularly to ensure its normal operation and service life.
