What is the difference between an electric heating tube and an electric heating wire?

1. What are the causes of electric heating tube heating?
The heating of the electric heating tube is due to the internal resistance wire inside the electric heating tube. Once the internal resistance wire is energized, heat is generated and transmitted to the surface of the metal of the electric heating tube by magnesium oxide powder with good insulation and thermal conductivity. In this case, the surface of the electric heating tube will quickly heat up, which will play a heating role.
People often say that electric heating tubes can heat due to the presence of electric heating wires, which are usually divided into two types: iron chromium aluminum and cobalt chromium alloy wires. There are some differences in price and material between these two types of electric heating wires.
Price: Iron chromium aluminum is cheap and affordable, while cobalt chromium alloy wire is more expensive compared to iron chromium aluminum.
Material: 1. Iron chromium aluminum is used in the atmosphere at high temperatures. The highest temperature used for iron chromium aluminum electric heating wire 0CrCr27AAL77MoMoMo2 can reach 1400 ℃, while the highest temperature used for cobalt chromium wire Cr20Ni80 is only 1200 ℃.
2. Under the same high humidity conditions in the atmosphere, the service life of electric heating tubes is longer than that of cobalt chromium alloy wires.
3. Nickel chromium wire has good antioxidant properties, while iron chromium aluminum has weak antioxidant properties.
2. What is the difference between an electric heating tube and an electric heating wire?
The difference between an electric heating tube and an electric heating wire is that the surface of the electric heating tube is not charged, and the surface of the electric heating wire is charged. Electric heating wire is used in a closed space. Due to the fact that the surface of the electric heating wire needs to be charged when heated, the electric heating tube is usually used for electric heating environments, such as air and liquid. Due to the tight filling of magnesium oxide powder between the electric heating wire and the electric heating tube casing, the surface of the electric heating tube is non-conductive. The relationship between electric heating wire and electric heating tube is very close. Electric heating wire is the raw material of electric heating tube, so the cost of electric heating wire is lower than that of electric heating tube.
