What are the factors causing the burst of electric heating pipes in water tanks?

The bursting of the electric heating tube in the water tank has caused many customers a headache. So what caused the electric heating tube in the water tank to burst?

The main factors causing the burst of the electric heating tube in the water tank are:

1. Scale

The larger the scale, the more it affects the heat conduction of the electric heating tube to the liquid. Heat conduction will not disappear, and the surface load of the electric heating tube will become higher and higher. Due to the principle of thermal expansion and contraction, the electric heating tube will burst.

2. Strength

Electric heating tubes used for heating water are usually designed at a power of 1:2 per meter (power per meter refers to the power that the electric heating tube can provide within one meter of heating area), and can be provided at a ratio of 1:3 when the water quality is good. If it exceeds the scale design, the power generation per meter will increase, and the ground load will also increase; As the surface load increases, the surface temperature of the electric heating tube will also increase, and the electric heating tube will burst due to thermal expansion and contraction.

3. Dry burning

Dry burning can cause a rapid increase in surface temperature of the electric heating tube in the water tank, resulting in excessive internal temperature of the electric heating tube. The electric heating tube will explode due to thermal expansion and cold contraction.

Therefore, the explosion factors of the electric heating tube in the water tank mainly include the above points. After understanding more parameters, we can help you design a more suitable electric heating tube.
