Why does the mold heating tube burst?
Many mold heating pipes have cracked and burst pipes soon after they are used. What is the matter? Let us come and analyze the reasons with you.
1. The power of the heating tube
Electric heating tubes have a certain power range. If the power is too high, the surface load is too large, and the internal temperature is too high, it will easily cause internal expansion, resulting in tube burst.
2. The material of the tube
Electric heating tubes are generally made of stainless steel. Depending on the specific conditions of use, the material of the stainless steel tube is also different.
3. Magnesium oxide powder inside the electric heating tube
If the above two are OK, it may be the problem of magnesium powder.
If the magnesium powder cannot meet the technical requirements during the processing and drying process, water will enter, and the thermal expansion of the water will cause great pressure on the pipeline, and even have the potential of leakage.
In addition, if the quality of the magnesium powder in the electric heating tube does not meet the standard, or there are impurities in the magnesium powder, high temperature use will also lead to storage.
4. The use environment of the tube
The size of the tube must be selected according to the hole diameter of the mold. It should be closely matched with the mold during installation. It is strictly forbidden to contact with the air, and it is strictly forbidden to dry it in the air. Can not be used in wet environment, it will also lead to burst tube.
In addition to the above four points, we also need to carry out regular maintenance on the heating pipe to prevent it from getting damp and causing the insulation to decline. If your pipes often burst, you can check the above points and pay attention to avoid them.
