U-shaped heating rod

The U-shaped heating rod is a highly efficient electric heating element, utilizing stainless steel or carbon steel metal tubes as the outer shell, with built-in electric heating alloy wires (such as nickel-chromium or iron-chromium alloys) and filled with magnesium oxide insulation material. Both ends are sealed with silicone and secured with a threaded fastening structure. The surface is wrapped with metal heat dissipation fins to expand the heat dissipation area, which can reach 2.5-4 times that of ordinary smooth tubes, while the surface heat load is increased by 2-3 times.
Structural Features
Efficient Heat Dissipation: The shortened tube design reduces self-heat loss, enabling faster heating and higher thermal efficiency at the same power.
Safe Sealing: Silicone sealing and threaded fastening structures ensure airtightness.
Customization: Supports customized production of power, dimensions, and shapes (such as U-shaped, ring-shaped, etc.) to meet the needs of different equipment.
Application Scenarios
Industrial Heating: Widely used in hot air circulation and equipment moisture prevention in industries such as mechanical manufacturing, automotive, textiles, and food processing.
Power Equipment: Used for moisture prevention and dehumidification in power equipment like switchgear and ring main units to ensure operational safety.
Typical Parameters
Power Range: Customized according to requirements, with common power reaching 2-3 times that of ordinary smooth tubes.
Temperature Resistance: Some models support high temperatures up to 900°C, with built-in temperature sensors and PID control for precise temperature regulation.
