What is the difference between wear-resistant ceramic pipes and wear-resistant metal pipes ?

1.Comparison of structure and performance

The wear-resistant ceramic pipeline adopts Wear resistant metal pipes as the external support structure, and the wear-resistant ceramic layer is lined to withstand the impact and wear of the medium, which has excellent wear resistance and corrosion resistance. In contrast, ordinary Wear resistant metal pipelines are usually not equipped with lining anti-wear materials inside. Although the exterior is consistent with the wear-resistant ceramic pipes using paint as an anti-corrosion coating, the interior has a significant disadvantage in wear resistance and corrosion resistance. Based on the above differences, in the cement, thermal power, steel and other industries with high requirements for anti-wear, wear-resistant ceramic pipelines have become the preferred choice for transportation system pipelines.  

2.Structural difference analysis  

From the perspective of pipeline structure, Wear resistant metal pipe are generally composed of only one or two layers of steel structures. In the process of transporting materials, the inner wall is susceptible to material impact and wear, and then wear-through occurs. The structural design of the wear-resistant ceramic pipe is more complex, including three layers of external steel structure, intermediate wear-resistant ceramic adhesive transition layer and internal corundum ceramic wear-resistant material. Among them, the internal corundum ceramic wear-resistant material is fired at more than two thousand degrees Celsius to form a dense corundum ceramic structure. Its Mohs hardness can reach 9.0, and it has excellent wear resistance. From the analysis of chemical properties, the chemical composition of the material is Al 2O 3, which is a neutral substance. Even at high temperature, it is not easy to react with steel, air, acid and alkali, so it has good corrosion resistance. In addition, its smooth inner wall also gives the pipeline a certain anti-scaling characteristics.  

3.Application fields and performance advantages  

Wear-resistant ceramic pipes have a wide range of media adaptability and can be used to transport various solid, liquid and gas media. They have successful application cases in cement, steel, thermal power, metallurgy, mining, coal, lithium and other industries. It has been verified by practical engineering applications that the wear resistance time of the wear-resistant ceramic pipe can reach more than ten times that of the quenched steel, fully demonstrating its significant advantages as an efficient wear-resistant pipe.
