Electric heating tubes are generally divided into two types: single ended tubes and two ends

Electric heating tubes are made by adding heating elements to metal tubes and tightly filling the gaps with crystalline magnesium oxide powder with good heat resistance, thermal conductivity, and insulation, which is then processed by other processes. It can be roughly divided into two types: single ended pipes and double ended pipes. The cross-section is divided into circular, semi circular, triangular, and flat shapes. This product has advantages such as long service life, good mechanical strength, high thermal efficiency, and easy installation. It is widely used in various saltpeter tanks, melting furnaces for fusible metals, air heating furnaces, drying boxes, hot pressing molds, and other devices.

The electric heating tube series is mainly divided into seven common types: single end heating tube, fin heating tube, flange heating tube, titanium heating tube, quartz heating tube, explosion-proof heating tube, and tetrafluoro heating tube. Let's talk about the introduction and application of each type:

1. Single ended heating tube: It is a metal tube filled with high resistance electric heating alloy wire heating material. It is filled and enriched around the electric heating wire, with good insulation performance, and can use high-purity magnesium oxide with high thermal conductivity as the filling material. It has high power, high thermal efficiency, and fast heat dissipation. Single ended heating tube

It is commonly used for heating plastic packaging, small mold heating, analytical instruments, and cooling effects when various gases expand.

2. Finned heating tube: Wrap heat dissipation fins around the surface of the metal tube to dissipate heat. Mainly used in shoe making machinery, chemical machinery, pharmaceutical machinery, electric ovens, centrifuges, battery factories, battery factories, clothing factory steam furnaces, automated electronic equipment, wave soldering, reflow soldering machinery, washing dry soldering machinery, and refrigeration equipment for air medium heating.

3. Flange type heating tube: High temperature resistance wires are evenly distributed inside the high-temperature resistant stainless steel seamless tube, and crystalline magnesium oxide powder with good thermal conductivity and insulation performance is densely filled in the gap. This structure is not only advanced, high in 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 tube, and then transfers to the heated component or air, To achieve the purpose of heating.

Product application: The flange type heating tube heats various media, such as flowing or stationary liquids and gases, through forced or natural convection. It is suitable for heating liquids in various containers, tanks, and solution tanks.

4. Titanium heating tubes: Used in industries such as chemical industry electroplating and metal processing. Practice has proven that titanium materials have small specific gravity, high strength, and corrosion resistance. Our company (Yancheng Hongtai Alloy Electrical Co., Ltd.) produces titanium heating tubes with high efficiency and long service life in the production and application of anti-corrosion equipment. Titanium heating tubes are suitable for various environments.

5. Quartz heating tube: As the name suggests, the material of the tube is quartz tube, which has advantages such as fast heating, good infrared radiation, and small thermal inertia, making it suitable for paint drying; Printing and dyeing, cardboard box shaping and drying; Food baking; Dehydration of medicinal herbs; Container disinfection, etc.

6. Explosion proof heating tube: It is composed of an explosion-proof heating tube and an explosion-proof junction box. Mainly used for heating media such as hydrogen, limestone, chloroform, turbine oil, and natural gas. Anti riot level: dellCT1, safe and reliable.
