Electric heating wire mainly consists of nickel chromium electric heating wire and iron chromium electric heating wire

Electric heating wires are divided into civil electric heating wires and industrial electric heating wires according to their main purposes.

The civil electric heating wire is mainly used for the production of civil electric heating pipes and other civil purposes, with a wire diameter generally between 0.6 and 0.15mm;

The diameter of industrial electric heating wire is generally between 0.8-8mm. Industrial electric heating wire has the characteristics of wide use, fast heating, and high power. In addition to being used for industrial electric heating pipes, it is also used for other industrial equipment, such as high-temperature furnace electric heating wire, vacuum furnace electric heating wire, annealing furnace electric heating wire, industrial baking box electric heating wire, and tin furnace electric heating wire. Selection of sealing materials

a. The selection principle of pipes: temperature resistance and corrosion resistance.

b. Selection of resistance wires.

c. Selection of magnesium oxide powder.

d. Selection of sealing materials: Firstly, stainless steel 301 material, which hardens during processing deformation, is used in various high-strength situations. In the process of manufacturing stainless steel heating pipes, the most commonly used material is stainless steel 304 material, which is widely used in heating liquids (without strong acidity or alkalinity) and air heating. It has good comprehensive performance, is easy to form, and is affordable. It is most commonly used in the manufacturing of heating pipes. The stainless steel 302 material is actually a variety with a higher carbon content than 304, and has higher strength after cold rolling. Stainless steel electric heating pipes can only be made of different stainless steel materials according to different working environments, and specific problems can be analyzed.
