Will excessive scale on the heating tube affect its life?

In the sales process, when we asked the customer what the quality of the water to be heated was, the customer was very surprised. What is the relationship between the life of the heating tube and the water quality. I am very serious here to tell everyone that the water quality directly determines the service life of the electric heating tube, because scale is the natural enemy of the electric heating tube of the water tank, and the service life of the electric heating tube is different for different water quality. I will explain to you today that too much scale on the electric heating tube will affect the lifespan?

Water heating pipes are generally used, and the proportional relationship between power and length should be considered when designing. Under normal circumstances, a meter-long heating tube can be designed for 1-4KW, and the maximum is 4KW. When heating pure water, the service life of the heating tube in this range will be greater than 1 year. However, when heating water sources with harder water quality and easier scale formation, the power per meter should not exceed 2KW. Otherwise, the life of the heating tube will be less than one year. The more serious the scale, the shorter the life of the heating tube.

This is because the greater the power per meter, the higher the surface temperature, and the higher the surface temperature, the faster the scaling will be. When more and more scale covers the entire heating tube, the heat in the heating tube cannot be quickly dissipated due to the scale barrier, which will increase the surface temperature of the water heating tube, and then cause the internal temperature of the heating tube to increase. When the temperature is high To a certain extent, the resistance wire in the tube will be blown, and in serious cases, the tube will burst. In this way, the heating tube cannot be used when the electricity comes in.

From the above, we can see how the scale affects the life of the electric heating tube, so the most possible prevention of scale production is the key to ensuring the life of the water heating tube. Therefore, we will ask about the water quality before the customer orders the heating tube, design the power and select the material according to the water quality, so as to fundamentally solve the problem of scale.
