How to deal with scale on electric heating tubes?

When stainless steel electric heating tubes heat water, scale inevitably forms. Especially in areas with poor water quality, scale can accumulate and form a thick layer on the surface of the heating tubes.

I. Harms of Scale on Electric Heating Tubes:

1. Scale has a low thermal conductivity, which can easily waste energy.

2. Excessive scale has poor thermal conductivity, causing excessively high temperatures inside the heating tubes, shortening their service life.

3. Excessive scale can easily breed bacteria and, in severe cases, cause cracks and damage on the surface of the heating tubes, posing a risk of electric shock.

II. Scale Treatment Measures

1. Recommendation: Our company has developed a coated, corrosion-resistant and scale-resistant electric heating tube. The advantage is that the coating allows the corrosion-resistant material to be seamlessly bonded to the tube wall, resulting in faster heat transfer and a coating that resists detachment. Testing and customer experience have shown significant results.

2. If the heating environment is prone to scaling, you can add a magnesium rod to the container to reduce scale accumulation. Use high-quality, large-diameter quartz heating tubes. This prevents scaling on the surface and, more importantly, the continuous infrared radiation it produces can soften the water.

3. When heating liquids, ensure that the heating zone is kept away from the liquid to minimize scaling. After heating, disconnect the power supply for a period of time to reduce the risk of prolonged dry heating on the surface of the heating tube, which can lead to scaling. Then, heat again.

4. The heating environment can easily affect scaling, so regular maintenance and cleaning of heating tubes are essential. When heating, avoid rapid temperature changes. Generally, maintaining the water temperature below 50°C will minimize scaling.
