Avoidance measures in the use of electric heating tape

　　With the development of science and technology, the electric accompanied by the heat tape in the pipeline antifreeze heat preservation application is more and more widely. However, electric accompanied by tropical in the use of the process may appear some problems, such as overheating, aging, corrosion, etc., these problems will not only affect its normal work, but also may bring about security risks. Therefore, it is particularly important to understand and take effective measures to avoid. In this paper, we will discuss in detail the electric accompanied by tropical in the use of the process should be taken to avoid measures.

　　First, the basic principle of electric accompanied by tropical

　　The electricity accompanies the tropical is a kind of through the electric energy transforms into the heat energy, the pipeline carries on the heat compensation antifreeze heat preservation product. It mainly consists of conductive polymer, metal wire, insulation layer and protective layer, in which the conductive polymer is electric accompanied by tropical heating element, when through the power supply will be hot.

　　Second, the electric accompanies the tropical use process may appear the problem and the avoidance measure

　　1. overheating problem and avoidance measures

　　Electric accompanied by tropical in the process of using may appear overheating problem, this is mainly due to improper installation or improper use caused by. Overheating will not only affect the normal work of electric accompanying tropical, but also may cause fire and other security risks. Therefore, it is very important to take effective avoidance measures.

　　Avoidance measures:

　　(1) Selection is reasonable: in electric accompanied by tropical selection, need to consider electric accompanied by tropical higher exposure temperature, accompanied by the heat pipe material is able to withstand accompanied by tropical higher surface heating temperature, so as to avoid the pipeline is scalded.

　　(2) Installation specification: Electric accompanied by tropical installation, whether winding or laying, need to be installed in accordance with a certain proportion, do not part of the laying is very compact, part of the spacing is very large. The electric accompanies the tropical belt to lay straight on the pipeline, should be installed in the pipeline slanting below 45°, in order to facilitate the transmission of heat.

　　(3) Use special material: when electric accompanying tropical installation, use special aluminium foil tape to increase the heat area, so as to ensure the accompanying heat effect, especially reflected in the large diameter of the accompanying heat, the effect is better.

　　2. Aging, corrosion problems and avoidance measures

　　The electric accompanies the tropical belt in the long-term use process may appear the aging, the corrosion problem, this is mainly due to the environmental factor or the medium to the electric accompanies the tropical erosion caused by. Aging, corrosion will not only affect the normal work of the electric accompanied by tropical, may also shorten its service life. Therefore, it is very important to take effective avoidance measures.

　　Avoidance measures:

　　(1) regular maintenance: in order to ensure that the electric accompanied by the tropical long time use and does not appear aging, corrosion and other problems, need to carry out regular maintenance. Maintenance operation includes regular cleaning electric accompanied by the tropical surface, check the electric accompanied by the tropical surface whether there are cracks, deformation and other problems, as well as the pipeline medium for dirt cleaning.

　　(2) Control the temperature and pressure of the medium: the high temperature and high pressure of the medium in the pipeline will cause damage to the electric accompanied by the heat tape, accelerate its aging and corrosion. Therefore, in the use of electric accompanied by tropical, need to reasonably control the temperature and pressure of the medium in the pipeline, in the permissible range of the use of electric accompanied by tropical.

　　(3) Selection of anti-aging and anti-corrosion materials: in the manufacture of electric accompanied by tropical, need to choose the material with anti-aging and anti-corrosion ability, in order to ensure the quality of electric accompanied by tropical. For example, the alloy material usually has the better anti-corrosion ability, in the use of electric accompanied by the heat, can choose the alloy material manufacture of electric accompanied by the heat, in order to reduce the pipeline medium on its corrosion.

　　3. Store and use environmental problems and avoidance measures

　　The electric accompanies the heat in the storage and the use process may be affected by the environmental factors, such as moisture, corrosion, etc. These problems will not only affect the normal work of the electric accompanies the heat, but also may shorten its service life. Therefore, it is very important to take effective avoidance measures.

　　Avoidance measures:

　　(1) Do a good job of waterproof work: when the electric accompanied by the tropical exposure in the air, to avoid the rain and snow and other bad weather formation of water infiltration, so as to avoid the electric accompanied by the tropical system caused by the damage, so the water should be cleaned up in a timely manner. In addition, it is necessary to do waterproof work after cleaning up the water, in order to improve the overall safety of the electric accompanying heat products.

　　(2) Correct preservation: for the long term storage after the electric accompanied by the heat tape, should carry on the inspection and maintenance before using. Inspection includes checking whether the connection of wire is loose, whether the insulation layer is broken, whether there is damage and other problems. If any problem is found, it should be replaced or repaired in time. At the same time, for the storage time is longer electric accompanies the tropical, should pay attention to its rainproof waterproof and so on whether the external environment exists the bad situation, avoids in the use causes the safety hidden danger.

　　Third, the importance of electric heat tape avoidance measures

　　Electric accompanied by tropical in the use of the process may appear some problems, such as overheating, aging, corrosion, etc., these problems will not only affect its normal work, but also may bring the security risks. Therefore, it is especially important to understand and take effective measures to avoid. By taking reasonable selection, standardised installation, regular maintenance, control of medium temperature and pressure, selection of anti-aging and corrosion-resistant materials, waterproof work and correct preservation and other measures, can effectively avoid the electric heating tape in the use of the process of the problems that may arise, to ensure its safe and reliable operation.

　　To sum up, it is suggested that in the use of electric accompanied by the tropical process, must follow the correct methods and precautions, in order to ensure its safe and effective use.
