Heating tube is used to convert electrical energy to thermal energy heating element, it can be used alone or as an electrical component used in a variety of electric equipment. Heating tube in a separate use should pay attention to the conditions of its work and some operational issues to ensure the use of electric heating tube safety and heating effect.
 
1, the working conditions of electric heating pipe
There are no special requirements for the temperature of the working environment, but the humidity of the air in the environment can not be more than 95%, and there is no inflammable, explosive or corrosive gas. The external working voltage of the heating tube can not exceed 1.1 times of the rated voltage. Before the electric heating tube is operated, the shell must be grounded effectively to avoid the electrical accident.
 
2, the operation of electric heating tube attention
Electric heating tube is easy to melt metal or solid state of nitrate, paraffin, asphalt and other substances, the first heating material to melt, then you can reduce the external voltage electric tube, when the melting is completed and then restored to rated voltage. In addition, the heating tube heating nitrate salt and other prone to explosion of the material, it is necessary to give full consideration to safety measures.
 
Electric heating pipe for air heating, pay attention to the uniform arrangement of electric heating tube, the advantage of doing so is to ensure that the electric tube has a more adequate and uniform cooling space, and as much as possible to ensure that the air flow and improve the heating efficiency of electric heating tube. The inner space of the electric heating pipe is filled with magnesia sand, and the magnesia sand at the outlet end of the electric heating pipe is easily contaminated due to the infiltration of impurities and water, so pay attention to the state of the outlet end of the electric heating pipe in operation to avoid the leakage accident.
 
Storage location of the heating tube must be kept dry and the appropriate insulation resistance, if you find the use of electric heating pipe storage environment insulation resistance is too small, can be low voltage power to be restored before use. Electric heating pipe should be properly fixed before use, the wiring part should be placed outside the insulation layer, and avoid contact with corrosive, explosive media and water. Heating tube for liquid or solid metal heating, it is necessary to pay attention to the heating tube must be completely placed in the object, not allowed to burn the case of electric heating pipe. After the use of electric tube if the outer shell of metal scale or carbon scale, it should be promptly removed, to avoid the heat pipe heat dissipation and service life impact.
 
 
Electric heating tube to be used with caution

Electrothermal tube as a common electric heating element, the main energy is converted to heat, it can be applied to a variety of electric equipment can also be used alone. According to the report, the electric tube in a separate use often occurs leakage, or shortened life expectancy and so on. Swiss high to remind customers, such problems may be due to the choice of unqualified products (here for your recommendation Rui high quality electric tube), on the other hand Rui Gao reminded to use the following points to pay more attention:
 
■ electric heating tube for air heating, pay attention to the uniform arrangement of electric heating tube, the benefits of doing so is to ensure that the electric tube has a more adequate and uniform cooling space, and as much as possible to ensure that the flow of air to improve the heating efficiency of electric heating tube .
 
■ heating tube for the easy melting of metal or solid state of the nitrate, paraffin, asphalt and other substances, the first heating material to melt, then you can reduce the external voltage electric tube, when the melting is completed and then restored to the rated voltage. In addition, the heating tube heating nitrate salt and other prone to explosion of the material, it is necessary to give full consideration to safety measures.
 
■ electric heating tube for the liquid or solid metal, it is necessary to pay attention to the heating tube must be completely placed in the object, not allowed to burn the case of electric heating pipe. After the use of electric tube if the outer shell of metal scale or carbon scale, it should be promptly removed, to avoid the heat pipe heat dissipation and service life impact.
 
■ The inner space of the heating tube is filled with magnesia magnesia, the magnesia sand at the outlet end of the electric heating pipe is easily contaminated by the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the electric heating tube in operation to avoid the leakage accident .
 
■ The storage location of the heating tube must be kept dry and appropriate insulation resistance, if you find the use of electric heating pipe storage environment insulation resistance is too small, can be low voltage power to be restored before use. Electric heating pipe should be properly fixed before use, the wiring part should be placed outside the insulation layer, and avoid contact with corrosive, explosive media and water.
