Material requirements and comprehensive characteristics of stainless steel tubular heater
The material requirements and comprehensive characteristics of stainless steel tubular heater are as follows:
Material requirements
1. Among the factors that affect the quality of stainless steel electric tubular heaters, the quality of material selection is very important.
2. The main reason is to choose the material of the electric heating tube reasonably, which is the premise of ensuring the quality of the electric tubular heater.
3. The selection principle of pipes: temperature resistance and corrosion resistance.
4. The general selection of resistance wire drops: Cr20Ni80
5. Selection of magnesium oxide powder: industrial grade magnesium oxide powder
6. Selection of sealing material: silicone oil +704 sealant
Edit this paragraph comprehensive features
1. Small size and large power: the inside of the electric heater mainly adopts bundled tubular heating elements, and each bundled tubular electric heating element has a maximum power of 5000KW.
2. Fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency.
3. Wide application range and strong adaptability: The circulating heater can be applied to explosion-proof or ordinary occasions, its explosion-proof grade can reach B and C grades, and its pressure resistance can reach 10Mpa. It can be installed vertically or horizontally according to user needs.
4. High heating temperature: the maximum operating temperature of the heater design drop can reach 850 ℃, which is not available for general drop heaters.
5. Fully automatic control: Through the heater circuit design, it is easy to realize automatic control of parameters such as outlet temperature, pressure and flow, and can be networked with a computer to realize human-machine dialogue.
6. Long life and high reliability: the heater is made of special electric heating materials, and the designed power load is more reasonable. The heater uses multiple protections, which greatly increases the safety and life of the heater.
