Reasons why electric tubular heater are often broken
1. First, we have to find out the specific situation of the electric heating element used by customers:
(1) Working environment: heated liquid or air dry burning? What is the operating temperature? Is there a temperature control?
(2) the design size and parameters of the heating rod itself: tell us the approximate heatingelement size, voltage, and power? And the material?
(3) If it is convenient, you can inform us of the origin and the order price of the tubular heater that they ordered, so that we can make a preliminary judgment on its quality.
2. Secondly, we need to give analytical judgment based on the data provided in the first step, which can be judged from the following aspects:
(1) If it is initially judged that the design of the heating element itself is beyond the standard (here, the standard refers to the ratio of the heating area of the electric heating tubular element to the power, and the professional point is that the surface load exceeds the standard), we will give suggestions , Or redesign for free.
(2) If it is initially determined that the design of the heating tubular itself does not exceed the standard, then we analyze from these small entry points:
△ Is the voltage wrong? (Refer to our common questions: 1. How to distinguish the rated voltage of the electric heating tubular from the working voltage? 2. What should be paid attention to when determining the rated voltage of the heating element?)
△ If it is heating corrosive liquid, is the material of electric heating tubular element selected properly? (Reference: Material Selection Table for Suwaie company [Note: The file may be slightly larger. If you click it and it does not load immediately, you can refresh the loading page to display it. If you still ca n’t see it, you can contact us]
△ When designing the heating element, do you consider the pressure bearing of the heating element? Generally, the normal ordinary electric heating tubular bears a pressure of 0.6MPA.
△ If it is a heating liquid, for example, is there any problem with the installation of the heating pipe of the screw flange, such as: Is there a dry burning in the heating area of the heating pipe?
△ If it is heated air, is there no fan circulation or temperature control?
△ What is the quality of the water if it is heated? Is the scale serious? (Reference: The effect of scale on the heating pipe)
△ If it is heating oil, what about the oil? What is the flow rate of the oil? (Reference: What to do if the heat-conducting oil heating tube is easy to form carbon?)
△ If it is a mold electric heating tubular element, check whether the diameter of the cartridge heater and the hole clearance of the mold hole are kept within 0.1mm, and whether there is temperature control? (Reference: Precautions for the design and use of the cartridge heater of the mold)
The above are just some of the main analysis points. If your tubular heater is always broken, it is not because of the above reasons. Welcome to call us for consultation and we will do our best to solve the problem for you.

How to use electric heating tubular so as not to break easily?
1. Can't fall, it should be fixed after use.
2. When the two terminals of the electric heating element are connected together, the resistance of the electric heating element is only half of the original. After the circuit is connected, the current flowing through the electric heating element is twice the original;
3. According to what you said, after connecting the two terminals of the two electric heating tubular, they are respectively connected to the power strip and heated in the water. This is very dangerous for boiling water, high power and instability, resulting in electric heating pipes Damage; In addition, part of the heat in the air of the electric heater is large and easy to damage.
