Product Description

High-purity Big Caliber Alumina Ceramic Tube
Top One Product
It is widely used in some special parts which require high strength,high hardness,heat-resistance,corrosion resistant and wear-resistant.

(1) Big caliber ceramic tube made of 92% alumina is widely used in industry of minning,power,metallurgical,coal,chemical and so on.it works as lining in pipe for transport of powder material and corrosive material, such as sand,ash, slag and chemical.
In some special site where wear plates can not service well, ceramic tube is a perfect substitute. It is a solution to problem of partial wear plate dropping off and has been enjoying high reputation.

(2) Big caliber ceramic tube made of 95% alumina is used as lining of hydraulic cyclone for paper-making and mineral separation.And most ofthe textile ceramic components are made of alumina 95%.

(3) Most of the ceramic spools,structural ceramic components are made of alumina 99%.The future is bright and the consumption quantity is increasing year by year.
