Precautions for using defrosting electric heating tubes

Precautions for using defrosting electric heating tubes

1. The components should be stored outside of the dry environment. If the insulation resistance drops below 1 megaohm due to long-term storage, they can be dried in an oven at around 200 ℃ for several hours (or the components can be low-voltage for several hours), that is, the insulation resistance can be restored.

2. When carbon deposits are found on the surface of the pipe, they must be completely removed before use to avoid reducing efficiency and even burning out components.

3. When melting solid oils such as asphalt and paraffin, the voltage should be lowered and used, and then increased to the rated voltage after melting. To prevent concentration of electricity and reduce the service life of components

The U-shaped electric heating tube has a simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids, acids, bases, and salts, and is also suitable for heating and melting low melting point metals They are all made by inserting electric heating wires into seamless metal pipes (carbon steel pipes, titanium pipes, stainless steel pipes, copper pipes), and tightly filling the gaps with crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the electric heating wire are connected to the power supply through two lead out rods, and the gaps are filled with magnesium oxide powder with good thermal conductivity and insulation, which is then shrunk into various shapes required by the user.

The U-shaped electric heating tube is made of a metal tube as the outer shell, and spiral electric heating alloy wires (nickel chromium, iron chromium alloy) are uniformly distributed along the central axis of the tube. The gaps are filled and compacted with magnesium oxide sand with good insulation and thermal conductivity. The ends of the tube mouth are sealed with silicone or ceramic. This metal armored electric heating element can heat air, metal molds, and various liquids Uniformly distribute high-temperature resistance wires inside high-temperature resistant stainless steel seamless pipes, and densely fill the gaps with crystalline magnesium oxide powder with good thermal conductivity and insulation performance. This structure is not only advanced and has high thermal efficiency, but also generates uniform heat. When there is current passing through the high-temperature resistance wire, the heat generated diffuses through the crystalline magnesium oxide powder to the surface of the metal pipe, and then transfers to the heated part or air to achieve the purpose of heating.
