High-power electric heating tube

High-power electric heating elements are devices that convert electrical energy into thermal energy, featuring high power density, rapid heating characteristics, and high mechanical strength. They are widely used in industrial heating scenarios.
Structure and Working Principle
Constructed with stainless steel materials (such as 304/316L stainless steel) in a tubular structure, filled internally with magnesium oxide powder as an insulating and thermally conductive material. Heat is generated by energizing a spiral resistance wire.
Key Parameters
Power Range: Common power ratings range from 60W to 2000W, with customizable higher-power models (e.g., ultra-miniaturized designs with a diameter of 2mm) 

Voltage Compatibility: Supports various voltage specifications from 24V to 380V to meet the needs of different equipment
Temperature Resistance: Operating temperatures can reach 600°C to 927°C, with some models supporting even higher temperatures
Application Scenarios
Suitable for heating industrial equipment such as plastic injection molding machines, 3D curved glass hot bending machines, pharmaceutical machinery, as well as high-temperature scenarios like chemical tanks and molten metal furnaces.
Technical Features
Thermal Efficiency: Energy conversion rate exceeds 95%, with some models reaching up to 98%
Heating Speed: Can reach rated temperature in as little as 15 minutes
Safety Design: CE certified, supports overheat protection and insulation protection
