Electric heating tubes also require their own maintenance to extend their lifespan. Common electric heating tubes have a certain degree of bursting phenomenon

The occurrence of these phenomena is a headache. Through a large amount of facts and analysis, it generally focuses on the following aspects:

(1) Long term burning of electric heating tubes leads to burning, leakage, and tube explosion

(2) The power of the electric heating tube is too high and the load is too large, causing the electric heating tube to burst;

(3) The pipe material of the electric heating tube is too thin and the wall thickness is not enough;

(4) Poor filling and packaging inside the electric heating tube.

During the use of electric heating tubes, over time, they may sometimes crack. The specific reasons are summarized by Shanghai Zhuanghai Electric Appliances, and there are several possible reasons:

During the use of electric heating tubes, it may be mostly groundwater or tap water, which contains a lot of impurities and is prone to scaling.

2. The quality of the magnesium oxide yarn used in the electric heating tube is poor, and after the electric heating tube works, the inferior magnesium oxide expands.

3. The external material of the electric heating tube may be the thin wall thickness of the tube, or it may be a stainless steel seam tube, which makes the electric heating tube prone to cracking

4. The power of the electric heating tube is too high, exceeding the surface load of the electric heating tube.

Environmental conditions for the use of electric heating tubes

1. The altitude shall not exceed 1000 meters.

2. The ambient temperature is -20 ℃ to 50 ℃.

3. The relative humidity of the surrounding air shall not exceed 90% (when the ambient temperature is 25 ℃).

4. There are no conductive dust, explosive gases, or corrosive gases that can seriously damage metals and insulation materials in the surrounding area.

5. There is no obvious impact or vibration.
