Alumina Industrial Ceramic Tube
My factory looking for distributors.
Advantages of alumina industrial ceramic tube
1. Alumina ceramic tubes have a high melting point and can withstand the high temperature environment inside the furnace, meeting the needs of various high-temperature processes.
2. Alumina ceramic tubes have good thermal stability and can maintain structural integrity during the heating and cooling process of furnace tubes.
3. Alumina ceramic tubes have high strength, ensuring the safety and reliability of furnace tubes during long-term use.
4. Alumina ceramic tubes have high hardness and can effectively resist particle wear and prolong the service life of furnace tubes when transporting materials or gases containing solid particles.
5. Alumina ceramic tubes have excellent chemical stability and are not easily corroded when in contact with various chemical media inside the furnace tube.
6. A dense layer of alumina film will form on the surface of the alumina ceramic tube, which can prevent oxygen from further reacting with the internal materials and thus has good oxidation resistance.
Applications of alumina industrial ceramic tube
1. Alumina ceramic tubes can operate reliably in some heat treatment furnaces that require periodic heating and cooling.
2. Alumina ceramic tubes can be used in heating furnaces with corrosive media in industries such as chemical and metallurgical.
3. Alumina ceramic tubes can be used in furnace tube applications that require electrical insulation, such as electric furnaces and electric heating furnaces, to avoid safety accidents caused by leakage and also help improve heating efficiency and control accuracy.
4. Alumina ceramic tubes accurate size control and good surface quality can meet the strict requirements of different furnace types and processes for furnace tube size and shape.
