Industrial heater s are mainly divided into single-headed heating tubes (cartridge heaters) and double-headed heating tubes in terms of the structure of the heating tubes. Single-headed heating tube is not as widely used as double-headed heating tube, but it is still widely used in some fields due to its own structural characteristics. It is often used for heating of mold holes and heating of oil tanks. Today I will introduce the characteristics of single-head heating tube for your reference.
Appearance. The most obvious one is the short size. Although the heating tube is short in size, it never affects the reduction of its own power, but has a high surface load
Service life. The cartridge heater is heated in the mold hole. To be honest, the service life is not as good as theoretically imagined. Due to the poor heating conditions and fast exothermic rate, the electrically heated external stainless steel tube is often burned, oxidized and deformed, causing the internal heating element - the electric heating alloy wire to be blown off and fused, which in turn shortens the service life of the cartridge heater due to the high temperature.
Good insulation performance. Cartridge heater has excellent insulation performance. Especially in the cold state, it can maintain good insulation performance.
High operability. Even if several cartridge heaters are used at the same time. It will not interfere with each other, and can easily complete the wiring in the box.
