al2o3 tube

Alumina Ceramic

Advantage

1. Material Composition: al2o3 tube is made of 99.3% alumina, so it is also known as alumina ceramic tube and possesses the excellent properties of alumina ceramics.

2. Operating Temperature: The alumina ceramic tube has excellent high - temperature resistance. It can be used stably for a long time at 1600℃. In a short period, it can even withstand a high - temperature environment of ≥1800℃.

3. Porosity: The porosity of the alumina ceramic tube is nearly zero. This characteristic makes its surface smooth, making it difficult for dirt to adhere, and it is very convenient to clean.

4. Customization Service: To meet the diverse needs of different customers, we provide custom - sizing services for alumina ceramic tube. We will do our best to meet any specification requirements.

Application

1. Alumina ceramic tubes can be used as material conveying pipelines to effectively prevent food from being contaminated. During the pharmaceutical production process, they can serve as reaction vessels or conveying pipelines to ensure the purity of drugs.

2. In the metallurgical industry, alumina ceramic tubes are commonly used for the diversion of high - temperature melts. In the chemical industry, they can be used as corrosion - resistant and high - temperature - resistant reaction tubes or heat - exchange tubes.

3. Whether it is a small precision instrument or a large - scale industrial equipment, a suitable alumina ceramic tube can be found.
