1. During the process of filling, impurities are mixed in magnesium powder, which will be carbonized by high temperature these impurities, and the heating tube fracture will occur during use;
2. It is important for the selection. There are many stainless steels, and the correct material is selected according to the environment used in the heating tube; the pipe itself also has the difference between the sewing tube, one is a seamless tube, the slit tube is welded with steel belt. If there is a little soldering, it will fry. Generally, there is no such problem in the event, it may be caused by seamless tube;
3. Stainless steel electric heating tube is also different from the liquid, some are corrosive liquids, some are water, and the heating water is sometimes water quality, because many may be used underwater, or tap water, more impurities, easy knot, scale, scale Too much too thick, can cause internal temperatures that cannot be spread, resulting in heating tube explosion tubes
4. The heating pipe wall is too thin or the heating tube power is set too high. The surface load is too large, and the internal temperature is too high, and it is easy to cause internal expansion of the heating tube, causing the heating tube to rupture.
