The material and production process of each link have a direct impact on the final product of the single head heating tube

The shape of electric heating materials can generally be divided into strip and wire. The heat load of the strip is 20% -50% higher than that of the wire. Generally, the electric heating wire inside the electric heating tube uses spiral wire.

A single head heating tube is composed of five main parts: an outer tube, an electric heating wire, an extraction rod, magnesium oxide powder, and a sealing material. The material and production process of each stage have a direct impact on the final product of the single head heating tube.

General insulation materials include caustic magnesium, crystalline magnesium oxide powder, aluminum oxide, clean quartz sand, modified magnesium oxide, etc. Different insulation materials will be used in single head heating tubes with different requirements. Let me introduce the usage range of different insulation materials to you:

1. Caustic magnesium is suitable for single head heating tubes below 300 ℃;

2. Quartz sand is suitable for single head heating tubes below 400 ℃;

3. Aluminum oxide is suitable for single head heating tubes below 500 ℃;

4. Crystalline magnesium oxide is suitable for single head heating tubes below 600 ℃;

5. Modified magnesium oxide is suitable for single head heating tubes below 800 ℃.

The external environment, heating environment, installation method, and maximum temperature of equipment have a significant impact on the load intensity of electric heating tubes. What is the impact of the load on electric heating tubes? Through the above introduction, we can understand that the quality of electric heating tubes is directly related to their load and has a direct impact on product selection. Therefore, product selection must be carefully considered.
