After being used for a period of time, the electric heating tube will break due to many factors. After this kind of phenomenon occurs, most customers will attribute the responsibility to the unqualified quality of the heating pipe, and the manufacturer will cut corners in production. In fact, this is not entirely true. There may be quality problems. Today, Yancheng huihouying will help you analyze the factors causing this phenomenon. We roughly classify the following points:

        Let's take a look at the introduction and characteristics of electric heating tubes:

        Introduction to electric heating tube:

        The electric heating pipe is formed by installing electric heating wires into seamless metal pipes (carbon steel pipe, titanium pipe, stainless steel pipe and copper pipe), filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then processing into various shapes required by users. It has the advantages of simple structure, high thermal efficiency, good mechanical strength and good adaptability to harsh environment. The electric heating tube can be used for the heating of various liquids and acid-base salts, and is also suitable for the heating and melting of metals with low melting point.

        Features of electric heating tube:

        When making the electric heating pipe, the metal electric heating element is used as the heating body. According to the requirements of different heating pipe power and voltage, the resistance wire is made into a spring shape with a winding machine, then the electric heating wire is threaded into the seamless steel pipe, and then the protective sleeve is tightly filled with magnesium oxide powder with good insulation and heat conduction. Finally, the pipe diameter is narrowed by the pipe shrinking machine. This manufacturing process can not only make the oxide medium dense, but also ensure that the electric heating wire is isolated from the air, so that it does not offset at the central position and touch the pipe wall. Avoid uneven conduction or heating on the surface of the electric heating tube.
