Maintenance before use:
1. Stainless steel electric heating pipe should be stored in a dry warehouse. If the surface is tidy due to long-term placement, the insulation resistance is measured using the application megohmmeter. If less than 1 mega / 500 volts, the electric heating pipe should be dried in 200 degrees.
2. Stainless steel electric heating pipe should read in detail before installing, especially stainless steel electric heating tube heating tube media, should have no erosion of stainless steel electric heating tube materials. To avoid damage to the error.
Maintenance in use:
1. Stainless steel electric heating pipe terminals should be kept clean, dry, and it will reduce the insulation performance and is short-circuited. If there is a chemical corrosion, flammable, explosive liquid or gas, the electric heating pipe wiring should be used. It is strictly protected by an insulating seal to prevent accidents. The application of 2 nuts is relatively fastened when wiring, and it is not necessary to force the screw to prevent the electric heating tube damage.
2. Stainless steel electric heating pipes should be immersed in the heating medium, avoiding heat dissipation of the heat and exceeding the allowable heating temperature to damage the electric heating tube. In addition, the wiring lead portion should expose the insulation layer or heater in the heater, so that this portion should not be damaged.
3. When the stainless steel electric heating is heated, such as sodium nitrate, stearic acid, stone, etc., should reduce the supply voltage when heating is heated to reduce the heat of electric heating pipe, when all melts become liquid, then To the rated voltage (the voltage should not exceed 10% of the rated voltage indicated by the various electric heating pipes, if applicable to the amount of heat generated below the rated voltage, the heat generated by the electric heating tube will also decrease.) A heating.
4. The lonind the stainless steel electric heating tube, and if the surface is aggregated, but the scale should be cleaned regularly, otherwise it will reduce the heat transfer performance of the electric heating tube and cause the tube surface heat load to exceed the rated permission.
