High-power electric heating tubes are efficient heating devices in the industrial sector, with a core structure consisting of a stainless steel shell, spiral resistance wire, and magnesium oxide powder, converting electrical energy into thermal energy. Their notable features include high power density (1-17W/cm2), high-temperature resistance (600-927°C), long lifespan (over 6000 hours), and high insulation (insulation resistance ≥1MΩ). ?
Core Parameters
?Power Range?: 60W to 2000W, with customizable ultra-compact designs (e.g., 2mm diameter) or extra-high-power models (e.g., 30KW). ?
?Voltage Support?: Ranging from 24V to 380V, adaptable to various industrial scenarios. ?
?Temperature Resistance Limit?: Stainless steel materials can withstand up to 850°C, with some models supporting temperatures up to 900°C. ?
Application Scenarios
?Industrial Equipment?: Electric boilers, chemical containers, reaction kettle heating. ?
?Special Requirements?: Medical equipment, food processing machinery, pipeline heating systems. ?
Customization Services?: Support for non-standard designs such as special-shaped tube bending and mold thermal balance optimization. ?
Typical Cases
?3D Glass Hot Bending Machines?: Tube diameter 12mm, power 350W, temperature resistance 927°C, used for curved glass molding processes. ?
?Boiler Electric Heating Tubes?: Maximum power 5000KW, pressure resistance 10Mpa, used for open/closed container heating. ?
Precautions
Ensure the effective heating area is fully immersed in liquid or solid metal; dry firing is strictly prohibited. ?
When melting low-melting-point metals (e.g., asphalt, paraffin), reduce voltage first for melting before raising to rated voltage. ?
If insulation resistance drops below 1MΩ after long-term storage, dry in a 200°C oven to restore performance.
