I The composition and structure of the electric heating tube:

Stainless steel electric heating tube (electric heating tube) is made of 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.

II 2、 Performance of electric heating tubes:

Stainless steel electric heating tube (electric heating tube) is made by placing electric heating elements in a metal tube and tightly filling the gaps with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation. It is processed by other processes. The utility model has the advantages of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation, long service life, etc. Widely applicable to various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, melting furnaces for fusible metals, air heating furnaces, drying furnaces, drying boxes, hot pressing molds and other devices.

III 3、 Use of electric heating tubes:

Stainless steel electric heating pipes are electrical components that specifically convert electrical energy into thermal energy. Due to their low price, convenient use, easy installation, and pollution-free nature, they are widely used in various heating situations. Stainless steel electric heating pipes have a long service life, with a general design service life of 1 year

Uniformly distribute high-temperature resistance wires in 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, 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
