The method of using electric heating tubes to heat objects is very simple
It is to use the Joule effect generated by the electric current to effectively transform the electric energy into heat energy to heat the material. Such a heating method can also be divided into direct resistance heating and indirect resistance heating, and the actual demand is different. If the electric heating tube is directly heated by resistance, the power supply voltage can be directly applied to the object to be heated, and when current flows through, the object to be heated can heat itself. The object directly conducting resistance heating must be a conductor and have a higher resistivity. Because the heat is generated from the object being heated, the thermal efficiency must be high.

What caused the rupture of the single-head heating tube?

1. During the powder filling process, the magnesium powder is mixed with impurities, these impurities will be carbonized at high temperature, and long-term use will cause the tube to rupture;

2. The choice of materials is very important. There are many types of stainless steel. We have to choose the right material according to the environment in which the heating tube is used. In addition, the pipeline itself is also different. If there is no welding, the pipe will break. Normally, this problem does not generally occur in a seamless pipeline. So this may also be caused by the quality of the seam pipe;

3. Stainless steel electric heating tubes use different liquids for heating. Some are corrosive liquids, some are water. The heating speed may also be related to the water quality. Many may be groundwater or tap water, so there are many impurities, and it is easy to form scale and scale. Too thick and too thick will cause the internal temperature to be unable to disperse, and then cause the heating tube to burst.

4. The wall of the heating tube is too thin, or the power setting of the heating tube is too high, the surface load is too large, and the internal temperature is too high, which only causes the internal expansion of the heating tube and then causes the heating tube to rupture.
