Corundum ceramic wear-resistant pipe, also known as corundum ceramic composite pipe, is essentially different from traditional steel pipes, wear-resistant alloy cast steel pipes, cast stone pipes, steel-plastic, steel-rubber pipes, etc.
The outer layer of corundum ceramic wear-resistant pipe is steel pipe and the inner layer is corundum. The Vickers hardness of the corundum layer is as high as 100-1500 (Rockwell hardness is 90-98), which is equivalent to tungsten-cobalt hard gold. The wear resistance is more than 20 times higher than that of carbon steel pipes, and its performance is much superior to that of commonly bonded corundum grinding wheels. The corundum layer in the ceramic steel pipe can wear away the corundum grinding wheel. The wear resistance of the ceramic steel pipe mainly relies on the corundum layer a few millimeters thick in the inner layer. Its Mohs hardness is 9, second only to diamond and silicon carbide. Among all oxides, it has The hardness is the highest.
Because the inner lining of the corundum ceramic wear-resistant pipe is corundum wear-resistant ceramic (a-AL2O3), the Mohs hardness can reach 9.0, which is equivalent to HRC90 or above. Therefore, it has high wear resistance to the abrasive media transported in metallurgy, electric power, mining, coal and other industries. It has been confirmed by industrial operation that its wear-resistant life is ten times or even dozens of times that of quenched steel.
The inner surface of corundum ceramic wear-resistant pipe is smooth and will never rust. It does not have convex spirals on the inner surface of seamless steel pipes. After testing of the inner surface roughness and clean water resistance characteristics by relevant testing units, the inner surface smoothness is better than that of any metal pipe, and the clean resistance coefficient is 0.0193, which is slightly lower than that of seamless pipes.
