Stainless steel electric heating tube maintenance features

- May 13, 2019-

1. The terminal of stainless steel electric heating pipe should be kept clean and dry, and vice versa, it will reduce the insulation performance and be short-circuited. If the environment is corrosive, flammable, explosive or other liquid or gas, the electric heating pipe connection part should be Use an insulated sealing device to protect against accidents. When the wiring is applied, the two nuts should be relatively fastened. Do not use too much force to avoid the loosening of the screw and damage the electric heating tube.

 

2. The heating part of the stainless steel electric heating tube should be immersed in the heating medium to avoid the heat dissipation and the electric heating tube is damaged beyond the allowable heating temperature. In addition, the wiring lead-out part should be exposed outside the heater's insulation layer or heater so that this part should not be overheated and damaged.

 

3. When the stainless steel electric heating tube heats some adhesives and other substances, such as sodium nitrate, stearic acid, paraffin, etc., the power supply voltage should be lowered when heating, so as to reduce the heat generation of the electric heating tube. Rise to the rated voltage (the voltage should not exceed 10% of the rated voltage indicated on the various electric heating pipes. If it is lower than the rated voltage, the heat generated by the electric heating pipe will also decrease).
