First, the explosion-proof immersion heater explosion-proof mark is ExdIIBT4 ExDIIBT6 ExdeIICT6 and so on.
Electric heating tubular can be widely used to heat water, oil, air, nitrate solution, acid solution, alkali solution and low melting point metal (aluminum, zinc, tin, babbitt).
1. Pipeline heater: The electric immersion heater is mainly used for installing in the air blowing pipe of the air heating system for blowing hot air. Can also be used as a variety of ovens, electric furnace heating elements.
2. Heating of nitrate salt solution, oil and water: welding the curved tubular electric heating element on the flange. The electric heating tube is used for heating in an open, closed solution tank and a circulation system.
3. Single-end heater: The electric heating element is used for the heating medium which can't be connected at both ends. It is suitable for use in hot core box, core shooting machine and other equipment.
Second, the performance advantages: electric heating element has a simple structure, high thermal efficiency, good mechanical strength, safe and reliable, sensitive and durable.
Third, the product structure: the heating pipe is filled with electric heating wire in the seamless metal pipe, the gap part is tightly filled with good thermal conductivity and insulating crystalline magnesium oxide powder.
