Application
ceramic tubes are widely applied across multiple fields. In the metallurgical industry, they serve as protective sleeves for thermocouples and high-temperature furnace components. In the chemical industry, they act as pipelines for transporting corrosive fluids and reaction vessels linings. In the electronic industry, they are used as insulating parts for electronic components and semiconductor manufacturing equipment. They also play an important role in new energy sectors like solar energy and nuclear energy, as well as in environmental protection equipment, demonstrating irreplaceable value in high-demand working conditions.
