Comprehensive characteristics of stainless steel tubular heater
The material requirements and comprehensive characteristics of stainless steel electric tubular heater are as follows:
I. Material requirements
1. Among the factors that affect the quality of stainless steel electric tubular heater, the quality of the material is very important
2. Reason. Reasonable selection of raw materials for tubular heater is a prerequisite for ensuring the quality of electric tubular heater.
3.Pipe selection principles: temperature and corrosion resistance.
4. Selection of resistance wire: Cr20Ni80
5. Selection of magnesium oxide powder: industrial grade magnesium oxide powder
6.Selection of sealing material: silicone oil +704 sealant
Second, comprehensive characteristics
1. Small size and high power: The bundled tubular heating elements are mainly used inside the electric heater, and the maximum power of each bundled tubular heating element is 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 used in explosion-proof or ordinary occasions. Its explosion-proof level can reach B and C levels, and its pressure resistance can reach 10Mpa. Can be installed vertically or horizontally according to user needs
4. High heating temperature: The maximum working temperature of this heater is designed to reach 850 ℃, which cannot be obtained by ordinary heat exchangers.
5. Fully automatic control: Through the design of the heater circuit, it is convenient to realize automatic control of parameters such as outlet temperature, pressure, and flow rate, and it can be networked with a computer to realize man-machine dialogue.
6. Long life and high reliability: The heater is made of special electric heating materials, and the design power load is reasonable. The heater has multiple protections, which greatly increases the safety and life of the heater.
