Alumina ceramic tubes have become a high-performance alternative to metal tubes, rubber tubes and ordinary ceramic tubes. With stable material structure and excellent comprehensive properties, alumina ceramic tubes significantly extend equipment service life and reduce operation and maintenance costs, making them the mainstream choice for purchasers.
Ⅰ、Core Advantages of Alumina Ceramic Tubes
1.Ultra-high hardness and excellent wear resistance
Alumina ceramic tubes have a Mohs hardness of 9, second only to diamond. Their wear resistance is several to more than ten times that of ordinary steel pipes.In the conveying of coal powder, slag, ash, and granular materials, the tube wall is not easily eroded, thinned, leaked, or ruptured, greatly extending the service life of the pipeline.
2.High temperature resistance, thermal shock resistance, and no deformation at high temperatures
They can work stably in environments of 1200℃–1600℃ for a long time, and withstand even higher temperatures in short-term use.
They do not soften, deform, or shed particles at high temperatures, nor do they release harmful substances. They are suitable for harsh working conditions such as furnace tubes, thermocouple protection tubes, high-temperature air ducts, and kiln accessories.
3.Excellent acid and alkali corrosion resistance, strong chemical stability
It has good resistance to acid, alkali, salt spray and organic solvent corrosion. In the transportation of corrosive media such as chemical industry, electroplating and sewage treatment, it will not rust, dissolve out or pollute materials.
4.High Electrical Insulation, Safe and Reliable
With high resistivity and stable dielectric properties, it is an ideal insulating protective tube for high-voltage, high-frequency and high-temperature environments, and is widely used in electronic appliances, insulating sleeves, electric heating devices and other fields.
5.Smooth inner wall, no scaling, low flow resistance
High density and smooth surface ensure low resistance in material conveying, no material adhesion and no scaling, improving conveying efficiency and reducing energy consumption and cleaning costs.
6.Stable dimension, high precision, long service life
Formed by high-temperature sintering with low linear expansion coefficient, no deformation or aging during long-term use, reducing replacement frequency and lowering overall procurement and maintenance costs.
7.Eco-friendly and clean, wide application range
No heavy metal precipitation, meeting the clean conveying requirements of food, pharmaceutical, high-purity gas and other industries, suitable for standardized and customized demands in various fields.
Ⅱ、Applicable industries and typical scenarios
