We manufactures custom technical ceramics, covering a wide range of customer requirements .We make use of several forming and machining techniques to process components made from alumina Ceramics, This material may be used in applications that require High elevated temperatures ,High dielectric strength, excellent electrical resistance, wear or corrosion resistance, high temperature capability, high Electrical insulation.
The alumina ceramic tube is molding in one, so slurry couldn’t permeate it.
Moreover, the technology of isostatic pressing is good for uniformity of ceramic
crystal structure, then its wear resistance is superior to ceramic tiles in same
material.

Product Advantages
1. Molding: Isostatic pressing
2. Wear-Resisitance: Approx 10times stronger than common pipes under same
conditions
3. Corrosion resistance: Strong acid or alkali resistant
4. Scouring abrasion resistance: Can bear scouring abrasion by large grain
material without damage
5. Good fluidity : Smooth surface ensure the free flow of material without
blocking
6. Low maintenance cost: Super wear-resistance reduce the maintenance
frequency and also the maintenance cost.
