Reason 1: the wall of the heating pipe is too thin or the power setting of the heating pipe is too high, the surface load is too large, and the internal temperature is too high, which is easy to cause the internal expansion of the heating pipe, thus leading to the rupture of the heating pipe.
Reason 2：is that in the process of powder filling, impurities are mixed in the magnesium powder, which will be carbonized after high temperature, and the tube will burst when it is used for a long time;
Reason 3: material selection is very important, there are many kinds of stainless steel, and the right materials are selected according to the environment of heating pipe; there are also differences in the pipe itself: one is the seam pipe, the other is the seamless pipe, the seam pipe is welded by steel strip, if there is a spot welding is not in place, the pipe will burst, generally the seamless pipe will not have this problem, which may be caused by the seam pipe quality;
Reason 4: the liquid used for heating of stainless steel electric heating pipe is also different. Some are corrosive liquid, some are water, sometimes the heating water is the water quality reason, because many of them may be underground water, or tap water, with many impurities, easy to scale, too much and too thick scale, which will cause the internal temperature can not spread, resulting in heating pipe explosion.
