Stainless steel electric heating tube - Industry Knowledge

1. The composition and structure of stainless steel electric heating tube:

The stainless steel electric heating tube is a metal tube as the shell, and the 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. Sealed in silicone or ceramic, this metal armored heating element can heat air, metal molds and various liquids.

2. The use of stainless steel electric heating tube:

Stainless steel electric heating tube is an electrical component that converts electrical energy into heat energy. Because of its low price, convenient use, convenient installation and no pollution, it is widely used in various heating occasions. The service life of stainless steel electric heating tube is very long, and the general design The service life is more than 10,000 hours.

3. Performance of stainless steel electric heating tube:

The stainless steel electric heating tube is made by placing electric heating elements in the metal tube, and filling the gap with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation, and then 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 various saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot stamping molds and other devices.
