Features:
1. The core material adopts DC arc welding to ensure various technical indicators such as surface load and resistance difference.
2. Heat-resistant insulating porcelain parts have good thermal shock resistance, high temperature resistance and long life. There are optional specifications for high, medium and low temperature furnaces and special atmosphere furnaces. The outer casing adopts seamless high-temperature resistant alloy pipe and coiled pipe, centrifugal cast pipe, non-metallic anti-carburizing casing, etc. Installation, testing, and maintenance are convenient, all performed outside the furnace.
3. The structure is compact, the performance is stable, the single power is large, and the service life is several times that of the ordinary electric heating tube.
Precautions for use:
1. When heating air, the components should be arranged crosswise and evenly, so that the components have good heat dissipation conditions, so that the air flowing through can be fully heated.
2. Safety measures should be considered when heating nitrate to prevent accidents.
3. The wiring part should be placed outside the insulation layer to avoid contact with corrosive, sexual media, and moisture; the lead wire should be able to withstand the temperature and heating load of the wiring part for a long time, and excessive force should be avoided when tightening the wiring screws.
4. The components should be stored in a dry place. If the insulation resistance is lower than 1MΩ due to long-term storage, they can be dried in an oven at about 200°C, or the voltage can be reduced and heated until the insulation resistance is restored.
5. Oxidation of the outlet end of the electric heating tube, avoid the infiltration of pollutants and moisture in the place of use, and prevent the occurrence of leakage accidents
