During the process of heating water with industrial electric heating pipes, damage to the electric heating pipes often occurs. How to understand the principles to avoid such incidents. During the process of damage to the electric heating tube, some were caused by material issues, while others were caused by human operation. We can choose high-quality products to solve the material problem of the electric heating tube, but for some parts of human operation, we need to strengthen the analysis of the causes of damage. According to the consultation and statistical materials, they are organized as follows:

When boiling water, it is necessary to place the electric heating tube in a non-conductive object to boil water, which must be higher than the heating surface, and do not touch the water on the joint to prevent leakage. The joints should be kept clean as much as possible, and should not be dry burned due to water shortage. It is easy to burn out, breakdown, and if the power is high, it can also cause the pipe to burst. The water plug or wiring must be in a wire with a rated current higher than the rated current, which is safe. It is best to have ground wiring and consider safety issues. If there is a trip, the water in the electric heating pipe should be dried and measured with a high-voltage instrument or a megohmmeter, The simplest way is to measure the leakage situation with a multimeter (DC level). Generally, the leakage should not exceed 50V. If it reaches 110V, it should not be used (which may cause electric shock) and replaced with a new electric heating tube. Also, what voltage do you use? Industrial 380V or household 220V. It depends whether you are using it for household or industrial use. Industrial use has grounding wires, and it is possible to equip it with a temperature control cabinet. At home, you can turn off the switch or open the switch when the water boils down (if possible, a thermocouple or a fuse can be connected to the temperature controller). Of course, boiling a kettle at home is simple. When the water boils, turn off the switch or open the switch. Some kettles will power off themselves after boiling, and the water must be higher than the heating surface.
