High-quality special-shaped heating tubes are heating devices that use high-temperature resistant stainless steel seamless tubes as the base, filled internally with high-temperature resistance wires and crystalline magnesium oxide powder. They feature high thermal efficiency and uniform heat distribution. The core structure includes:
Material and Process
Made from high-temperature resistant materials such as SUS310S, 304, 316L stainless steel, and quartz, with a temperature resistance of up to 900°C. The manufacturing process involves filling seamless metal tubes with resistance wires and then compacting the powder to ensure structural stability and sealing.
Shape and Function
Breaking away from conventional straight tube designs, they can be customized into non-standard structures such as Z-type, W-type, spiral, U-type, I-type, and square-shaped loops. They are suitable for applications like liquid/acid-alkali-salt heating, mold temperature control, plastic machinery, pharmaceutical production lines, and food processing.
Performance Characteristics
Quick Start: Reaches working temperature within 5 seconds
Energy Efficiency: High thermal efficiency with uniform heating
Dry Heating Conditions: Supports heating without a medium
Long Lifespan: Service life of over 5000 hours under normal use
Application Scenarios
Widely used in industrial heating equipment such as nitrate tanks, water tanks, oil tanks, acid-alkali tanks, as well as temperature control devices like air heating furnaces and drying ovens.
