Teflon electric heating tube is a new type of electric heating tube resistant to strong corrosion, used for heating various corrosive liquids. It has excellent anti-aging properties and good flexural properties, and is designed with low surface load. The joint adopts fully enclosed acid and alkali proof, non-heating section and overheating safety protection system are completely customized according to customer's needs. Perfectly guaranteed that the heater is not easy to burn, long service life, full sealing, no corrosion, no leakage, with grounding protection, safe and reliable. The applicable temperature is below 110 °C.
The storage position of the electric heating pipe must be kept dry and proper insulation resistance. If it is found that the insulation resistance of the storage environment of the electric heating pipe is too small, it can be restored after low voltage power supply. The electric heating tube should be properly fixed before use. The part of the wiring should be placed outside the insulation layer and avoid contact with corrosive, explosive media and water.
When used for heating liquid or metal solids, it must be noted that the electric heating tube must be completely placed in the object to be heated, and the electric heating tube is not allowed to be burnt. If the outer metal casing is covered with scale or carbon after the electric heating tube is used, it should be timely ** to avoid affecting the heat dissipation performance and service life of the electric heating tube.
When heating nitrates, paraffin, asphalt, etc., which are easily melted metal or solid, the heating substance is first melted. At this time, the external voltage of the electric heating tube can be lowered, and the voltage is restored to the rated voltage when the melting is completed. In addition, when the electric heating pipe heats a substance that is prone to explosion accidents such as nitrate, it is necessary to fully consider safety measures.
When used for air heating, pay attention to the uniform arrangement of the electric heating tubes. The advantage of this is to ensure that the electric heating tube has a relatively sufficient and uniform heat dissipation space, and as much as possible to ensure the fluidity of the air and improve the heating efficiency of the electric heating tube.
The internal gap is filled with magnesia oxide, and the magnesia sand at the outlet end of the electric heating tube is easily contaminated by the infiltration of impurities and moisture. Therefore, attention should be paid to the state of the outlet end of the electric heating tube during operation to avoid the leakage accident.
