Crush Resistance Alumina Ceramic Tube
basic characteristics of Crush Resistance Alumina Ceramic Tube
Alumina ceramics (mainly composed of α-Al₂O₃) as the inner lining material of pulp and pneumatic conveying pipelines is one of the ultimate solutions to extreme wear conditions. Crush resistance alumina ceramic tube extremely high hardness and excellent wear resistance make it perform exceptionally well when conveying materials with high hardness and high abrasiveness.
Why choose Crush Resistance Alumina Ceramic Tube
1. Ultimate wear resistance
Crush resistance alumina ceramic tube with a Mohs hardness of up to 9 (second only to diamond), Crush resistance alumina ceramic tube can resist the cutting wear of hard particles such as quartz sand, iron ore and slag.
Lifespan comparison
It is 10 to 20 times longer than ordinary steel pipes
It is 5 to 8 times longer than that of high-chromium alloy steel
It is more resistant to puncture and wear from sharp particles than rubber /UHMWPE.
2. Chemical stability
It is resistant to strong acids (except hydrofluoric acid and hot concentrated sulfuric acid), strong alkalis and salt solutions, and is suitable for pulp containing chemical agents or corrosive dust.
3. High-temperature adaptability
The long-term temperature resistance is ≥1600℃ (the inner lining layer itself), but the actual use is limited by the metal casing (generally used in working conditions ≤300℃).
4. Smooth surface & low resistance
The surface roughness is only Ra 0.4μm, reducing flow resistance and saving energy and reducing consumption.
