What causes fin heater explosion?

1. Internal reasons:

The power design of the electric heating tube is too large, the surface load is large, and the surface load is large. The surface temperature of the electric heating tube will rise, and the internal temperature will also rise. When the internal temperature of the electric heating tube is high to a certain extent, the electric heating tube will expand due to thermal expansion and contraction, and the electric heating tube will explode, which is called explosion.

When heating corrosive liquids with electric heating tubes, the material must be selected correctly. The corrosive liquid will slowly corrode the wall of the electric heating tube, causing small sand eyes. At this time, the electric heating tube is always powered on for heating, and the electric heating tube is prone to explosion due to thermal expansion and contraction.

The wall thickness requirements of electric heating tubes used in high-pressure environments are relatively high, basically seamless tubes with a wall thickness greater than 1.0mm. However, in order to reduce costs, some customers use welded pipes. When the electric heating is turned on, under the action of pressure, the electric heating tube is prone to small cracks, resulting in tube explosion.

2. External reasons:

When the voltage of the fin heater increases, the surface load of the electric heating tube increases, and the electric heating tube explodes. The reasons are the above.

Therefore, the common causes of electric heating tube explosions are the above points. As long as the electric heating tube is produced by a professional electric heating tube manufacturer, the power supply design is reasonable, the material selection is correct, and the wiring and installation instructions are correct, the electric heating tube will not explode.
