The importance and application of the anti-corrosion layer of electric heating tape

　　In the modern industrial production, electric accompanied by tropical as an important heating equipment, widely used in petroleum, chemical, electric power, pharmaceutical and other fields. However, due to the electric accompanied by tropical often exposed to harsh environments, such as high temperature, humidity, corrosive gases, etc., its anti-corrosion performance is particularly important. In this paper, we will discuss the importance of the anti-corrosion layer and its application.

　　First, the electric accompanied by the importance of tropical with corrosion layer

　　1. Extend the service life Electric accompanied by tropical in the process of use, if the lack of effective anti-corrosion measures, it is easy to be eroded by corrosive substances, resulting in equipment damage, shorten the service life. And the existence of anti-corrosion layer can effectively block the invasion of corrosive substances, prolong the service life of the electric accompanying tropical.

　　2. Improve the safety

　　Electric accompanied by tropical in the operation process will produce a lot of heat, if the anti-corrosion layer failure, may cause fire, explosion and other safety accidents. Therefore, the anti-corrosion layer can not only protect the electric accompanying tropical from corrosion, but also improve the safety of the whole system.

　　3.Reduce the maintenance cost

　　The maintenance workload of electric accompanied by tropical is very big, especially for those who are installed in the high altitude, underground or marine environment equipment, maintenance is more difficult, higher cost. And the existence of anti-corrosion layer can effectively reduce the number of maintenance and maintenance costs of equipment, improve the operational efficiency of equipment.

　　Second, the electric accompanies the heat tape to have the application of the anti-corrosion layer

　　1. Petrochemical industry

　　In the petrochemical industry, electric accompanied by tropical commonly used in pipelines, tanks, reactors and other equipment frost insulation. Because these equipments are often exposed to high temperature, humidity, corrosive gases and other harsh environments, the existence of anti-corrosion layer can effectively protect the electric accompanied by tropical from corrosion, prolong the service life of the equipment.

　　2.Electric power industry

　　In the electric power industry, the electricity accompanies the heat tape to be commonly used in the cable, transformer, switchgear and so on equipment frostproof heat preservation. Because these equipments are often exposed in the outdoor environment, the existence of anticorrosion layer can effectively protect the electric accompanied by the tropical from rain, salt spray and other corrosive substances erosion, improve the operational efficiency of the equipment.

　　3. Pharmaceutical industry

　　In the pharmaceutical industry, electric accompanied by tropical commonly used in the reaction kettle, storage tanks, pipeline and other equipment frost insulation. Because these equipments often contact with chemicals, the existence of anti-corrosion layer can effectively protect the electric accompanied by tropical from corrosion, to ensure the quality and safety of drugs.

　　4.Marine engineering

　　In the marine engineering, the electricity accompanies the tropical belt commonly used in the submarine pipeline, the sea platform and other equipment of anti-freezing heat preservation. Because these equipments are often exposed to seawater, salt spray and other corrosive environment, the existence of anticorrosion layer can effectively protect the electric accompanied by tropical from corrosion, prolong the service life of the equipment.

　　Third, the type and choice of anti-corrosion layer

　　1.Fluorine plastic anti-corrosion layer

　　Fluorine plastic anti-corrosion layer has excellent corrosion resistance, applicable to a variety of acids, alkalis, salt and other corrosive environments. Its high temperature resistance is also very good, can be used for a long time in the temperature range of -190 ℃ to 260 ℃.

　　2. Polyurethane anti-corrosion layer

　　Polyurethane anti-corrosion layer has good abrasion and impact resistance performance, applicable to a variety of mechanical abrasion and impact environment. Its corrosion resistance is also very good, can resist the erosion of various acids, alkalis, salts and other corrosive substances.

　　3. Epoxy resin anti-corrosion layer

　　Epoxy resin anti-corrosion layer has excellent adhesion and corrosion resistance, suitable for a variety of metal substrate corrosion. Its high temperature resistance performance is also very good, can be in -40 ℃ to 150 ℃ temperature range of long-term use.

　　In a word, the importance of the electric accompanied by the tropical has the anti-corrosion layer can not be ignored. Anti-corrosion layer can not only prolong the service life of the electric accompanied by the tropical, improve the safety, but also can reduce the maintenance cost, improve the operation efficiency of the equipment. In the actual application, the user should according to the specific working environment and the use of requirements, choose the appropriate anti-corrosion layer material and thickness, in order to ensure that the normal operation of the electric accompanied by tropical. In the future, with the progress of science and technology, the anti-corrosion layer of technology will be further development and innovation, for industrial production to bring more convenience and benefit.
