What does the water heating tube have to do with?

Water heating pipes are liquid heating tubes. The liquids here include general liquids (pure water, tap water, groundwater) and weak acid and weak alkaline water. The difference in water quality also affects the life of the electric heating tubes.

Heating tubes for heating liquid include threaded single-head heating tubes, U-shaped waterproof electric heating tubes, W-shaped electric heating tubes, threaded flange heating tubes, flat flange heating tubes, and so on.

1. Heating ordinary water

1). The power per meter is controlled between 1-3KW. Excessive power will accelerate the formation of scale. Once the scale condenses on the surface of the hydroelectric heating tube to a certain extent, it will hinder the heat conduction of the water heating tube. If it is too large, the surface temperature of the water heating tube will increase, which will cause the internal temperature of the heating tube to be too high and burn out the resistance wire. In severe cases, the electric heating tube will expand and cause tube bursting, thereby reducing the use of the heating tube. life. The power design is an important factor in the factors that affect the life of the electric heating tube.

2). It is necessary to ensure that the heating area of the water heating tube is completely immersed in the liquid. The surface temperature of the heating area of the heating tube is very high. In this way, the surface temperature of the heating tube will increase, which will cause the internal temperature of the heating tube to be too high and burn out the resistance wire, which will shorten the life of the heating tube.

3) The water quality in some areas is very hard and it is very easy to scale. At this time, the design of the heating tube must reduce the power per meter of the heating tube, generally within 2KW. Or use our developed anti-scale coating heating tube. Its effect is similar to that of a non-stick pan. The scale will automatically fall off to a certain extent, allowing the water heating tube to quickly dissipate heat and achieve the effect of protecting the heating tube. Otherwise, the heating tube has a short life.

2. Heating acid and alkali corrosive liquids

The heating of acid and alkaline liquids affects the life of the water heating tube. In addition to the dry burning phenomenon and the power exceeding the standard in the heating zone like heating general liquids, there is a more important point that is the material used for the heating tube. Acid and alkali resistant heating tube materials generally use 316L or titanium tubes. If corrosion-resistant materials are not used, the surface of the heating tube will be corroded, leaks will occur, and the life of the heating tube will be shortened.
