alumina ceramics tube insulation aluminum content 95% corrosion-proof long lifetime
product name:alumina ceramic tube
Introduction of alumina ceramics:
Alumina ceramic tube is formed by isostatic pressing process. It has regular size, complete specifications and strong weather resistance. It has strong adaptability to the external climate and is resistant to sunlight. It has the characteristics of high purity, good compactness, good wear resistance, corrosion resistance, good high temperature resistance, low wear and no abrasive pollution. The alumina content can be 99 %, 95 % and 92 %. It is mainly used in pharmaceutical production lines, laboratory heat treatment, chemical machinery manufacturing and so on. Alumina ceramic tube models have a variety of specifications, which can be customized to meet a variety of purposes.
