The void inside the electric heating tube is filled with magnesia, and magnesia oxide at the outlet end of the electric heating pipe group is very easy to be polluted by the environment due to the penetration of residue and water, so it is necessary to pay attention to the outlet end of the electric heating pipe group during actual operation to prevent the resulting electrical safety accidents. When the electric heating tube is used for air heating, pay attention to the uniform ordering of the electric heating pipe, the benefit of that is to ensure that the electric heating tube has a more sufficient and uniform heat exhaust indoor space, and try to ensure the air circulation, improve the heating efficiency of the electric heating tube.
The electric heating tube has no special requirements for the temperature of the working environment, but the ambient humidity of the air in the environment should not exceed 95%, and flammable and explosive materials or corrosive vapors should not be stored. The storage and discharge part of the electric heating tube is the same as that of platinum rhodium thermocouples and other components, it is necessary to maintain dry and moderate insulation resistance, if the insulation resistance of the storage and discharge environment of the electric heating tube is found to be too small, it can be applied again after low-voltage power supply is repaired. The electric heating pipe needs to be moderately fixed before application, and part of the wiring should be placed on the outside of the insulation layer to prevent contact corrosion
