A sheath heater is a heating element that surrounds a heating wire with an insulating material for electrical insulation, and further protects it with a metal tube on the outside. The lifespan is fundamentally a function of the wire diameter and temperature of the heating wire, but corrosion of the heater pipe can also limit its lifespan. Metals ultimately oxidize or chlorinate, leading to corrosion and forming metal oxides or metal chlorides. To minimize this change, methods such as "selecting a steel type suitable for the environment" and "applying surface treatments like pickling and electro-polishing" can be employed. **Main Factors Determining Heater Power Consumption** - Type of substance being heated - Mass of the substance being heated - Flow rate of the substance being heated - Pre-heating temperature (°C) and required post-heating temperature (°C) *For more details, please refer to the PDF document or feel free to contact us.*
