Common types of tubular electric heating elements

Tubular electric heating element is an electric heating element with high temperature stability, corrosion resistance and long life. It is widely used in various industrial heating fields, such as plastic molding machinery, heating furnaces, heat exchangers, food equipment, etc. Electric heater manufacturers introduce to you that according to the different materials, structures and processing technologies, there are mainly the following common types of tubular electric heating elements:

1. Stainless steel tubular electric heating element

Stainless steel tubular electric heating element is a commonly used heating element suitable for various working conditions. It is made of high-quality stainless steel and has good corrosion resistance and high temperature resistance. Its structural design is diversified, and stainless steel tubular electric heating elements of various shapes, powers and voltages can be customized according to user needs.

2. Alloy tubular electric heating element

Alloy tubular electric heating elements are mainly made of nickel-chromium alloy, chromium-aluminum alloy or iron-aluminum-chromium alloy. Its advantages are that it can maintain a stable resistance value at high temperature and has high corrosion resistance and mechanical strength. Alloy tubular electric heating elements are often used in high-temperature fluid heating, electric furnaces and heat treatment equipment.

3. Silicon carbide tubular electric heating element

Silicon carbide tubular electric heating element is mainly made of silicon carbide ceramic material, which has high high temperature resistance and corrosion resistance. It is a very excellent high temperature electric heating element. Silicon carbide tubular electric heating element can work stably for a long time in high temperature environment, and has good thermal conductivity and is not easy to absorb dirt.

4. Built-in tubular electric heating element

The built-in tubular electric heating element is a new type of heating element. Its heating tube is directly integrated into the heating medium and can directly contact the heated material to achieve rapid heating. The built-in tubular electric heating element is suitable for heating various media, including liquid, gaseous and solid media, such as water, oil, air, metal billets, etc.

5. U-shaped tubular electric heating element

The notable feature of the U-shaped tubular electric heating element is that it has a strong "U"-shaped bend, which can adapt to various heating occasions of different forms, especially in a small heating space. The use of U-shaped tubular electric heating elements can better meet the heating needs. At the same time, U-shaped tubular electric heating elements are also widely used in engine preheating, hydraulic oil heating and air heating.

The above are several common types of tubular electric heating elements introduced to you by electric heater manufacturers. Each element has different advantages and application ranges. Users can choose the appropriate type according to specific heating needs.
