Although the safety of single headed pipes has been constantly improving, we still need to pay great attention to the safe use of single headed pipes. Most of the single head tubes produced nowadays use core grinding equipment for their electric heating wires, with high standardization of pipe diameter and close coordination with equipment assembly, resulting in high thermal efficiency and fast heat dissipation. It is precisely because of these advanced manufacturing processes that the quality of many electric heating tubes produced today is more stable, improving the safety of equipment use.
Although the single headed tubes currently sold on the market are manufactured according to CE standards, they can meet the needs of most machines. But we should still pay attention to the safety of using electric heating tubes. For electric heating tube components, their working environment should be such that the relative humidity of the air is not more than 95%, and there are no explosive or corrosive gases. The working voltage should not exceed 1.1 times the rated value, and the casing should be effectively grounded. Insulation resistance ≥ 1M Ω Dielectric strength: 2KV/1min.
There is one more thing that needs special attention. The electric heating tube used should be fixed in position. The effective heating area must be completely immersed in liquid or metal solids, and empty burning is strictly prohibited. When scale or carbon deposits are found on the surface of the pipe, they should be promptly removed and reused to avoid affecting heat dissipation and shortening the service life.
When it is necessary to heat fusible metals or solid nitrate, alkali, asphalt, paraffin, etc., the operating voltage should be lowered first, and the rated voltage can only be raised after the medium melts. When heating air, the components should be arranged evenly and cross to provide good heat dissipation conditions and allow the flowing air to be fully heated.
Safe use of electric heating tubes is very important for both equipment and machinery! The safe use of electric heating tubes not only ensures the normal operation of machinery, but also effectively addresses production safety issues.
