The influence of the type of electric heating tape on the service life

　　As an efficient heating solution, electric heating tape is widely used in pipeline insulation, equipment heating, ground snow melting and other fields. However, there are significant differences in the service life of different types of electric traceable heat tape. In this paper, we will discuss several main types of electric heat tape and its impact on the service life. First, the type of electric accompanied by tropical

　　The electric accompanies the heat mainly to divide into three types: the self-limiting temperature electric accompanies the heat, the constant power electric accompanies the heat and the mineral insulation electric accompanies the heat. Each type has its unique characteristics and applicable scene.

　　1. Self-limiting electric accompanying heat: Self-limiting electric accompanying heat is a kind of electric accompanying heat which can adjust the temperature automatically. It contains special conductive material inside, when the temperature rises, the resistance of conductive material increases, the current decreases, so as to reduce the amount of heat; vice versa. This characteristic makes the self-limiting electric accompanying heat tape can keep stable temperature in different environment temperature, avoid overheating and damage.

　　2. Constant power electric accompanying heat: Constant power electric accompanying heat is a kind of electric accompanying heat with constant power. Its heat is not affected by the ambient temperature, always keep constant power output. Constant power electric accompanying tropical usually need to use with temperature controller, in order to achieve accurate temperature control.

　　3. mineral insulation electric accompanying heat: mineral insulation electric accompanying heat is a kind of mineral insulation material made of electric accompanying heat. It has excellent high temperature resistance, corrosion resistance and waterproof performance, suitable for high temperature, corrosive environment and need to fireproof occasion.

　　Second, the electric accompanied by the influence of the type of heat on the service life

　　Different types of electric accompanied by tropical in the service life there are significant differences, mainly by the following factors:

　　1. Material quality: The electric accompanies the tropical material quality to its service life has the important influence. High-quality conductive material, insulation material and sheath material can improve the durability and reliability of electric accompanying tropical, prolong its service life.

　　2. Temperature control: Temperature control is the key factor that affects the service life of electric accompanying heat tape. Self-limiting temperature electric accompanying tropical due to the ability to automatically adjust the temperature, to avoid overheating and damage, so its service life is relatively long. Constant power electric accompanying tropical need to use with temperature controller to prevent overheating and damage. If the temperature controller is faulty or improperly set, it may lead to overheating and shorten the service life of electric accompanying heat.

　　3. Use environment: the use of the environment also has an important impact on the service life of the electric heating tape. High temperature, corrosive environment and humid environment will cause damage to the material and performance of electric accompanied by tropical, shorten its service life. Mineral insulated electric accompanying tropical due to excellent high temperature resistance, corrosion resistance and waterproof performance, applicable to the harsh use of the environment, so its service life is relatively long.

　　4. Installation and maintenance: correct installation and maintenance method can prolong the service life of electric accompanying heat. When installing the electric accompanying heat tape, should avoid excessive bending, pulling and abrasion, make sure it is flat and firmly laid on the heated object. In the process of using, should regularly check the electric accompanied by the tropical intact situation and the controller's operation status, timely detection and treatment of faults, to avoid the electric accompanied by the tropical damage due to the long-term use of improper.

　　5. Frequent switching: Frequent switching of electric accompanied by heat will also affect its service life. Electric accompanied by tropical in the start and stop will produce large current impact, may lead to internal material fatigue and damage. Therefore, it is recommended that when using electric accompanying heat as much as possible to keep its continuous open state, avoid frequent switching. For the occasions which need intermittent use, can consider using timer or temperature controller to realise automatic control, reduce the influence brought by human operation.

　　6. Load Matching: Load matching of electric accompanying heat tape is also an important factor affecting its service life. If the power of electric accompanied by tropical power and the demand of heated object is not matched, it may lead to electric accompanied by tropical overload or underload, affecting its normal work and service life. Therefore, when choosing electric accompanying heat, it should choose suitable type and specification of electric accompanying heat according to the specific demand of heated object and environmental conditions to ensure that it can work stably and efficiently.

　　In summary, different types of electric accompanied by heat in the service life of significant differences, mainly by the quality of materials, temperature control, use of the environment, installation and maintenance, frequent switching and load matching and other factors. In the selection and use of electric accompanied by the heat, should consider these factors, choose the right type and specification of electric accompanied by the heat, take the correct installation and maintenance methods, in order to extend the service life of electric accompanied by the heat, improve its working efficiency and reliability.
