The structure, life, performance and classification of stainless steel electric heating tube

- Aug 07, 2020-

1. Composition structure of stainless steel electric heating tube

The stainless steel electric heating tube is made of a metal tube, and spiral electric heating alloy wires (nickel-chromium, iron-chromium alloy) are evenly distributed along the central axis of the tube. The gaps are filled and compacted with magnesia sand with good insulation and thermal conductivity. Both ends of the nozzle are used Sealed with silicone or ceramic, this metal-clad electric heating element can heat air, metal molds and various liquids.

2. Use of stainless steel electric heating tube

Stainless steel electric heating tube is an electrical component that specially converts electric energy into heat energy. Because of its low price, easy use, easy installation, and no pollution, it is widely used in various heating occasions. Stainless steel electric heating tube has a long service life and is generally designed. The service life is more than 3,000 hours.

3. Performance of stainless steel electric heating tube

Stainless steel electric heating tube is made by placing electric heating elements in the metal tube, and tightly filling the gap part with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation, and processed by other processes. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. It is widely used in all kinds of saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot press molds and other devices.
