1. The diameter is small and can reach 3-25mm.
2. The length is not limited and can reach 20-2000mm.
3. High power, 2-5 times the power of a normal electric heating tube, it can achieve a surface area of 20 watts per square centimeter, and even 60 watts per square centimeter in foreign countries.
4. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, no pollution, and low price. At the same time, it saves electricity and is safe to use. It can be bent into various shapes, lightweight, and easy to disassemble.
The size of a unit plane or object surface can increase calorie production by more than ten times. Then, use a shrinking machine to shrink the diameter of the pipe, making the oxygenated medium tight (with a density of over 3.3g/cm3), ensuring that the electric heating wire is isolated from the air and the core position does not shift and collide with the pipe wall. The lifespan of survival can also correspondingly increase to over 10 years. Compared to electric heating elements with the same thousand calories, tubular electric heating tubes can save 5% of electric heating materials, and the heating rate can reach over 90%.
The typical structure of a single head tube (the most popular structure) is the same as an electric heating tube, usually consisting of five parts: insulator, sealing material, lead out rod, supplementary material, electric heating wire, metal protective sleeve, and terminal. So. The spiral electric heating wire and the lead out are located in the center of the metal protective sleeve. Its manufacturing process involves threading the spiral electric heating wire into seamless steel pipes, copper pipes, or aluminum pipes. The gaps between them are evenly supplemented by a multi tube replenishment machine to provide both insulation and heat conduction oxygen medium, such as forming crystal oxygen gasification magnesium powder (which can also be aluminum oxide or clean quartz sand).
