Ceramic Pipe Lining Composition for Ash Slurry Operation
Ceramic tube pipe introduction
Chemshun alumina ceramic lined composite steel pipe not only has steel pipe characters of high-strength,good toughness, impact resistance, good weld-ability, but also has corundum ceramics characters of high hardness, high wear resistance, corrosion resistance, heat resistance. It overcome disadvantages of steel low hardness, poor wear resistance and ceramics poor toughness, therefore, ceramic lined pipes have comprehensive property of excellent wear resistance , hear resistance , corrosion resistance, mechanical shock and thermal shock, etc. It is the ideal pipeline of conveying sand, stone, coal, ash, molten aluminum etc particles and corrosive medium, Chemshun Ceramics offers sophisticated design and engineering capabilities of both standard and custom wear linings, installation and project management, as well as abrasion audits of used wear linings.
Chemshun alumina ceramic lined pipe advantage
- Long lifetime and maintenance free operation
- No operation interruption or production losses
- No contamination of the conveyed materials due to abrasion, mixture or oxidation
- Physiologically harmless, suitable for food products
- Smooth surface to achieve good flowability and to avoid plugs
- No spilled material to clean up
