How long is the life of a normal electric heating tube? This question is what everyone wants to ask. I will talk to you today.
In addition to the quality of the resistance wire, the life of the electric heating tube is also related to the quality of the magnesium oxide powder and the selection of the resistance wire diameter. For high temperature electric heating tubes, when selecting the diameter of the resistance wire, the surface load of the resistance wire needs to be calculated to meet the life requirements.
There are two determinants of the service life of the electric heating tube. One is the external environment and the frequency of use, the key is the ambient temperature, whether the heat dissipation state of the electric heating tube is good, and whether the electric heating tube is designed according to this environment; It is the inherent quality of the electric heating tube, and the service life is different with different materials.
Improving the life of the electric heating tube can start from these aspects:
First determine the heating medium, so as to choose what type of pipe material;
Secondly, ensure that the working voltage is not less than 90% of the rated voltage, so as not to damage the internal structure of the electric heating tube;
Third, proper maintenance and cleaning are also a necessary factor to increase life span!
