Hazards of Electric Heating Tubes and Precautions for Burning Water in Electric Heating Tubes

Electric heating tubes are widely used in industry for heating liquids, but the selection of heating rods for different liquids also varies. For example, for corrosive liquids, Teflon heating rods are usually used to heat the liquid.

When using an electric heating tube, it is best to have sufficient time and not leave midway, so that the power can be cut off immediately after boiling. When using it for the first time, the time can be calculated first to allow time for the water to boil. Additionally, it can prevent the electric heating rod from overheating and cracking, and it is important to stay away from children.

2. Do not use flammable materials around the electric heating tube. Sometimes circuit problems are uncontrollable and can easily ignite flammable materials in the vicinity when a short circuit occurs

3. When boiling water, make sure that the water has not passed through the electric heating tube, and do not dry burn the electric heating tube. Otherwise, the electric heating tube can easily burn out. At the beginning of using it, I made the mistake of thinking that the wires would leak electricity when placed in water. Later, the wires burned all over, but fortunately, there was no accident. I have seen someone online burn the barrel.

4. Let's take a look at the manufacturing principle of an electric heating tube. Its heating coil is usually made of a thinner metal tube, which contains an electric heating wire. Then, insulation materials such as magnesium oxide are poured into the tube, and the electric heating wire is encapsulated and fixed in the middle of the tube to prevent it from coming into contact with the tube wall. From this, it can be seen that when the electric heating tube is placed in water, there will be no electricity when we come into contact with water without power outage. I have tried it before, and I have also tried it with an electric pen. Therefore, if there is electricity during use, do not use it. It is called leakage, and it must be a low-quality product or damaged. You can use an electric pen to test it first, and if there is electricity, throw it away directly.

Although it is said that water will not have electricity, it is not recommended to test the water temperature when it is powered on, just in case there is an electric leakage? Is that right. Firstly, cut off the power supply and then test the water temperature. Although it may be troublesome, safety is more important.

6. The power supply must be stable, and if conditions permit, connect a trip switch to prevent automatic tripping due to leakage.
