The wear of industrial elbows has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials are also constantly innovating, and successively cast stone, cast steel, alloy, centrifugal cast composite ceramics and other materials. Among them, the pipeline-lined alumina ceramic has become the most widely used wear-resistant material due to its high wear resistance, high hardness, oxidation resistance, corrosion resistance and high resistance to high and low temperature strength, occupying the world's special ceramics. About 80% of the market share (abrasion resistant material).
Wear-resistant elbows are widely distributed in industries with severe wear such as thermal power, steel, smelting, cement, machinery, coal, mining, chemical, port terminals.
The ceramic composite pipe has a Mohs hardness of 9.0 equivalent to HRC90 or more because the inner liner is corundum ceramic (a-AL2O3). Therefore, the grinding media conveyed by the metallurgy, electric power, mining, coal and other industries have high wear resistance. It has been confirmed by industrial operation that its wear life is ten times or even several times that of hardened steel.
The ceramic composite tube is light in weight and suitable in price. It is 50% lighter than the inner diameter of the cast stone pipe; it is 20-30% lighter than the wear-resistant alloy pipe, and has good wear resistance and corrosion resistance, because of the long service life, thus the cost of the hanger, the handling fee, the installation fee, and Operating costs are reduced. According to the actual project budget and engineering actual comparison between the design institute and the construction unit, the cost of the pipe project is equivalent to that of the cast stone. Compared with the wear-resistant alloy pipe, the project cost is reduced by about 20%.
