Treatment method for easy scale formation on the surface of electric heating tube

In the process of using stainless steel electric heating tube, especially when heating water, it is easy to form scale on the surface, especially in some areas with poor water quality. The formation of scale can cause many disadvantages.

        The accumulation of scale will surround the heating tube layer by layer. The thermal conductivity of scale is very low, resulting in a waste of electricity. At the same time, due to a large amount of scale and poor thermal conductivity, the internal temperature of the electric heating tube is too high, which will greatly shorten the service life of the heating tube. Generally speaking, electric heating tubes with a service life of 3 years can only be used for half a year to 1 year when there is too much scale. In addition, the scale is easy to breed bacteria and pollute the water quality. In severe cases, it can also cause the surface of the heating tube to burst and damage, causing the risk of electric shock.

The following briefly introduces several methods to reduce the formation of scale,

1. At present, the most effective is the scale-resistant coating heating tube developed by our company's alloy technology. Its characteristic is that it does not change the external shape of the heating tube, and the power is not limited. The technical parameters of the ordinary heating tube are roughly the same. The characteristic is stainless steel. A layer of anti-fouling coating is added to the surface of the heating tube, and the effect is very obvious after testing and customer use results.

2. The extended steel core extruded magnesium rod is used and placed on the opposite side of the electric heating tube, which can effectively prolong the service life of the magnesium rod, ensure high protection of the inner tank and prevent the electric heating tube from scaling.

3. The quartz glass electric heating tube with an enlarged diameter is adopted. In some areas, the water quality is hard and the water is easy to scale. Because the base material of the quartz glass heating tube is high-purity silicon dioxide, the physical and chemical properties of silicon dioxide are not active. When heated, it is not easy to absorb impurities. In addition, the quartz glass heating tube is In the heating process, far infrared rays are emitted, which can soften the water quality to a certain extent, so this kind of electric heating tube is not easy to form scale.

4. Use an instant water heater. The water temperature of instant water heaters should be controlled within 50 degrees, that is, the critical temperature of scaling is 50 degrees. When taking a bath, it is lower than this temperature (usually 35 to 45 degrees), so it is difficult to build scale. Even in northern areas where the water hardness is relatively high, long-term use only slightly scales.

    These methods are currently the most effective way to solve the problem of easy scale formation on the surface of stainless steel heating pipes. If you have any questions, please contact our company.
