The direct thickness of the electric heating wire has a direct impact on the service life of the electric heating wire

1, The diameter and thickness of the electric heating wire:

The direct thickness of an electric heating wire has a direct impact on its lifespan. The thicker the direct thickness of the electric heating wire, the larger the surface area. If stored improperly for a long time, it will cause more oxides. At this time, in a certain temperature environment, relatively thick electric heating wires have a longer service life. Under normal circumstances, the diameter of the electric heating wire is generally not less than 0.3mm at the highest operating temperature.

Reasons for uneven heating of stainless steel heating pipes:

1, Selection of resistance wire:

When stainless steel electric heating tubes are not in production, we need to first solve a very important step by selecting high-quality resistance wires. The quality of the resistance wire directly affects the effectiveness of the electric heating tube during use. Non standard resistance wires may not be visible from the appearance. However, when using it, it can be found through efficiency that low-quality materials are used, and the conductivity cannot achieve the desired effect. Some have good heating effects, while others have poor heating effects.

2, Uneven gap between resistance wires:

After selecting high-quality resistance wires, we need to proceed with the wire drawing process. It is to stretch and wrap the resistance wire according to the design requirements. This process aims to ensure even gaps between the resistance wires, and only after power is applied can the electric heating tube evenly heat the object. Otherwise, the temperature in areas with high density will be too high compared to areas with low density, and this process is very important.

3, Improper filling of magnesium oxide powder:

We all know that the filling material inside the electric heating tube is magnesium oxide powder, but most factories still use manual filling, which can lead to poor control of the internal tightness during filling. The parts that are too tight will heat up slowly, while the parts that are too loose will heat up faster.

4, Installation issue with resistance wire:

When installing the electric heating wire into the tube, it is installed vertically, and gravity causes the electric heating wire to be uneven..
