Abrasion resistant alumina ceramic lining bend is manufactured by the high-tech production process-from Self-propagating. Abrasion resistant alumina ceramic lining bend create a new generation of abrasion and corrosion resistant engineering pipeline. The Abrasion resistant alumina ceramic lining bend is composed of three layers: ceramic, intermediate, and steel layers.
The composite pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500 degree. The molten alumina produced from the reaction
Fe2O3+2Al=2Fe+Al2O3
spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the steel pipe. They are widely used to convey highly abrasive material such as fly ash and any other fine powder material in mine, thermo power generating, coal processing plant, metallurgy, construction, etc. The service life is 10 to 20 times longer than the normal steel pipe.
It is the ideal product instead of steel or rubber lined pipe and elbow.

Advantages:
Good abrasion resistance
The liner is High quality wear ceramic with 95% Al2O3 which are sintered under 1700 ℃and the hardness are up to 85HRA which is 271.5 times of manganese steel or 1700 times of chrome steel plate. Special composite method and toughening formula ensure the ceramic not being too fragile to resist the impact of normal blocks.
Little loss during running
Low project cost
Light weight and longer lifetime to save the cost of support structure and handling charges. The charges is similar to basalt piping project, or 20-30% less than wear steel piping project.
Good thermal stability
-50 ~600 degree C is the ideal temperature.
Easy and fast to fix on site
Welding, flange, flexible joint are available.
