Why are wear-resistant alumina ceramic pipes more wear-resistant than high-chromium cast iron pipes?
High chromium cast iron pipes use high chromium cast iron as the main body of the pipe, and high chromium cast iron as structural support and wear resistance. The wear-resistant ceramic tube uses a metal outer tube as the structural support and high-purity alumina wear-resistant ceramics as the wear-resistant lining. It not only exerts the high hardness and wear resistance of the alumina wear-resistant ceramics, but also exerts the advantages of metal materials. It has the characteristics of high strength and toughness, and its wear resistance is greatly improved.
Theoretical research and experiments have shown that the wear resistance of pipelines mainly depends on the hardness of the anti-wear material. The Rockwell hardness of the alumina wear-resistant ceramic lining reaches HRA80-90, second only to diamond and 30% higher than high chromium cast iron. Above, this is the fundamental reason why its wear resistance far exceeds that of high chromium cast iron.
In addition, the ceramic lining of the wear-resistant ceramic pipe surpasses high-chromium cast iron in terms of strength and smoothness, which can also increase its wear resistance to a certain extent.
