Product Description
The alumina ceramic sleeve is a high-performance wear-resistant composite pipeline designed for severe abrasion conditions in pneumatic conveying systems. The product adopts a three-layer structure consisting of stainless steel pipe, high-strength adhesive, and 95% alumina ceramic lining. This design provides superior wear resistance, corrosion resistance, and stable operation under medium-temperature environments.
It is particularly suitable for lithium battery raw material conveying, cement powder transport, and mining material handling where pipelines suffer from rapid wear, frequent replacement, and high maintenance costs.
