Phenomena and causes of electric heating tube cracking

Jan 03, 2022

Summary of the cracking of the electric heating tube? For this problem, customers often call to inquire and say that my electric heating tube will not be used for long, and the tube will crack. This phenomenon is what we often call the phenomenon of tube bursting of the heating tube. This phenomenon is very common, and it is also fatal for electric heating tubes. Many customers directly ask us if it is the quality of the heating tube. In fact, there are many reasons for the phenomenon of electric heating tube bursting. The quality problem is only one aspect. Below, Shenzhen electric heating tube will sort out the general reasons for everyone:

   1. The so-called proper grasp is very important. If everything exceeds a certain degree, qualitative change will surely be achieved. The same is true for the stainless steel heating tube. The power setting of the stainless steel heating tube is too high, the surface load is too large, and the internal temperature is too high, which will easily cause the internal expansion of the electric heating tube, which will cause the tube to burst. As for the reasonableness of the power setting, customers can refer to our company’s article: How to determine the heating tube power? Or call us directly:


  2. The second possibility is the problem of magnesium oxide powder. There are many kinds of magnesium oxide powder, and the best one is modified magnesium oxide powder with high temperature resistance. If inferior magnesia powder is used, when the stainless steel heating tube is working, the internal expansion of the stainless steel heating tube will also occur, which will cause the tube to burst.


   3. The third possibility is that the outer material of the electric heating tube may be the thin wall of the tube, or it may be a stainless steel pipe with seams, which may cause the electric heating tube to easily crack.


4. The fourth possibility is the customer’s own problem. The stainless steel electric heating tube may use groundwater or tap water for heating. There are many impurities and it is easy to form scale. Too much and thick scale will cause the inside of the electric heating tube. The temperature cannot spread, causing the electric heating tube to burst.


   To sum up, the general reasons are the above, so if the heating tube bursts, we must figure out the reason, and then prescribe the right medicine, so as to improve the long life of the electric heating tube designed and manufactured by ourselves, and reduce the customer's cost of use.
