What are the characteristics of electric heating tube? The characteristic of the electric heating tube is that the surface of the electric heating tube is not charged when it is electrified. Due to the structural characteristics, the metal tubular electric heating tube has many advantages over other types of electric heating elements. For example, the utility model has the advantages of simple structure, low material consumption, low cost, long service life, high mechanical strength, high thermal efficiency, saving electric energy and safe use. It can be bent into various shapes. It is portable, easy to assemble and disassemble, and has a wide range of uses. It is especially suitable for portable household electric heating appliances.

After a long time of application practice, metal tubular electric heating tube has achieved good results in the following industries and equipment.
