Why does the electric heating tube burst and crack

1. Internal reasons:

The power design of the electric heating tube is too large, the surface load is large, the surface load is large, the surface temperature of the electric heating tube will increase, and the internal temperature will also increase, when the internal temperature of the electric heating tube is high to a certain extent due to the reason of thermal expansion and cold contraction, the electric heating tube will expand, and the electric heating tube will burst, which is how the electric heating tube will crack.
When the electric heating tube is heated with corrosive liquid, the material selection must be selected correctly. The corrosive liquid will slowly corrode the wall of the electric heating tube, and small trachoma will appear. At this time, the electric heating tube has been energized and heated, and the electric heating tube is also prone to explosion due to the reason of thermal expansion and contraction.
Normally, the wall thickness of the electric heating tube used in a large pressure environment is required, which is basically a seamless tube with a wall thickness greater than or equal to 1.0mm. However, some customers in order to reduce costs, the use of weld pipe, electric heating pipe is prone to small cracks under the action of pressure, resulting in the electric heating pipe burst.

2. External reasons:
The voltage of the electric heating tube is enlarged, which increases the surface load of the electric heating tube and also causes the electric heating tube to explode. The reason above is number one.
Therefore, the reasons that the electric heating tube may explode are more common, as long as the electric heating tube is done in a professional manufacturer, the power design is reasonable, the material selection is correct, and the correct wiring and installation guidance is carried out, the electric heating tube will not explode.
