Alumina Ceramic Tube | Wear Resistance

Alumina Ceramic

Advantages of Alumina Ceramic Tube

1. The hardness level of alumina ceramic tubes is close to diamond(Hardness Mohs 9), which can withstand significant wear and ensure a long service life even under harsh conditions.Alumina ceramic tubes are resistant to various chemicals and corrosive environments, making them suitable for corrosive media.

2. Alumina ceramic tubes maintain their strength and wear resistance at high temperatures(1600℃ for long-term use and 1800℃ for short-term use）, and maintain performance in environments involving thermal cycling or extreme high temperatures.

3. The smooth surface of the alumina ceramic tube reduces friction, further improving the wear resistance of dynamic systems with moving parts.

Applications of Alumina Ceramic Tube

1. A tube lining, chute, and conveying system used to transport abrasives such as sand, cement, and minerals.

2. In mining equipment, alumina ceramic tubes are used to protect components that are constantly subject to friction from abrasive ores and rocks.

3. Alumina ceramic tubes are used in pneumatic conveying systems, where abrasive particles are transported through pipelines under high pressure.
