Product Description

Alumina ceramic straight tube Corundum ceramic wear-resistant tube because the inner lining is corundum ceramic (a-AL2O3), the Mohs hardness can reach 9.0, which is equivalent to HRC90 or more. Therefore, it has high wear resistance to the abrasive media transported by metallurgy, electric power, mining, coal and other industries. It is confirmed by industrial operation that its wear life is ten times or even dozens of times that of quenched steel. The inner surface of corundum ceramic wear-resistant tube is smooth and never corrodes, unlike seamless steel pipe with convex spiral lines on the inner surface. The internal surface roughness and clear water resistance characteristics of the relevant testing units have been tested, and the internal surface smoothness is better than that of any metal pipe, and the clearing resistance coefficient is 0.0193, which is slightly lower than that of seamless pipes. Because the steel ceramic layer is (a-AL2O3), it is of neutral nature. Therefore, it has acid and alkali resistance and seawater corrosion resistance, and at the same time has anti-scaling properties. Because the corundum ceramic (a-AL2O3) is a single stable crystalline structure. Therefore, the composite pipe can operate normally for a long time in the temperature range of -50-700ºC. The coefficient of linear expansion of the material is 6-8×10-6/0C, which is about 1/2 of that of the steel pipe.
