How to prevent leakage of stainless steel electric heating tubes

Stainless steel electric heating tubes are mainly made of metal as the outer shell. A lot of alloy wires are coiled on the central axis of the tube. Both ends of the tube are sealed with silicone or ceramic to ensure its good working performance. Since stainless steel heating tubes use electricity as raw material to heat liquid and transfer heat energy, how to prevent stainless steel electric heating tubes from leaking electricity has also been a long-standing concern of customers.

If you want to prevent stainless steel heating tubes from leaking electricity, you must be extra careful when selecting materials and choose some suitable materials. The principle of selecting pipes is to choose some high temperature and corrosion resistant ones, because they must work in a high temperature environment during the heating process. If they cannot withstand high temperatures, what is the work efficiency and what is leakage prevention. Secondly, the resistance wire should be Cr20Ni80, and the magnesium oxide powder should also be selected when selecting some industrial grade magnesium oxide powder, which is not only stable in performance but also efficient. The sealing material of the tube mouth should be silicone oil + 704 sealant, otherwise it is easy to leak electricity and cause safety accidents.

How to prevent stainless steel electric heating tubes from leaking electricity? In addition to being careful when selecting the above materials, you should also pay attention to the following conditions.

1. The outer metal of the heating tube

If a stainless steel heating tube is used, scale or oil will definitely be generated after a period of use, so we must clean it regularly, otherwise the surface will be carbonized and cracked over time, which will easily cause leakage.

2. The heating tube must be completely immersed in the medium

If the medium heated by the heating tube is liquid, be sure to immerse the entire heating tube in the liquid, otherwise the heating tube will dry burn in the air, causing leakage or other safety accidents.

3. Setting the voltage of the heating tube

After the heating tube is connected to the power supply, set the voltage to 10% lower than the rated voltage, so that the internal temperature of the heating tube will not be too high, resulting in leakage.

4. Reasonable arrangement of wiring method

When wiring, be sure to arrange the wiring method reasonably, otherwise various lines will be entangled together, which is easy to cause leakage.

How to prevent stainless steel electric heating tubes from leaking electricity? The main thing is to do the above precautions. As long as you choose the corresponding pipe material, the corresponding resistance wire, and reasonably arrange the voltage and wiring method of the heating tube, the entire circuit will be well protected, allowing employees to feel at ease when operating.
