why tubular heater cracking

Summary of cracking of electric heating pipe? This problem often has the customer call to consult that my electric heating pipe can not be used for a long time, will appear the phenomenon of pipe cracking, this phenomenon is what we often say heating pipe burst phenomenon. This phenomenon is very common, and it is also fatal for electric heating pipes. Many customers directly ask us whether the quality of the heating pipe. In fact, there are many reasons for the phenomenon of electric heating pipe burst, the quality problem is only on the one hand, the following Shenzhen electric heating pipe for everyone to sort out the general reasons :1, the so-called grasp of moderation is very important, everything over a certain degree, will certainly achieve qualitative change. The same is true of stainless steel heating pipe. The power setting of stainless steel heating pipe is too high, the surface load is too large, and the internal temperature is too high, which can easily cause the internal expansion of electric heating pipe, which leads to the tube explosion. As for the rationality of power setting, customers can refer to our article: how to determine the power of heating pipe? The second possibility is the problem of magnesium oxide powder, which is divided into many kinds, among which the best is the modified magnesium oxide powder with high temperature resistance. If the inferior magnesium oxide powder is used, when the stainless steel electric heating pipe works, the internal expansion of the stainless steel electric heating pipe will also occur, thus the tube will burst. 3. the third possibility, the external material of the electric heating pipe may be the thin wall thickness of the pipe or the stainless steel sewn pipe, which causes the electric heating pipe to crack easily. 4. the fourth possibility is the customer's own problem, the stainless steel electric heating pipe may be used for heating water, or tap water, more impurities, easy scale, too much scale too thick, will lead to the internal temperature of the electric heating pipe can not spread, resulting in the tube burst. To sum up, the general reason is the above several, so if there is a heating pipe burst, we must find out the reason, and then the right remedy, so as to improve their own design and production of electric heating pipe life is very long, reduce the cost of customer use.
