In recent years, the application of wear-resistant ceramic pipes has become more and more common, especially in modern industry. Wear-resistant ceramic pipeline has excellent characteristics of heat resistance, corrosion resistance and wear resistance, and has been widely used in metallurgy, thermal power, steel, cement and other fields of pulverized coal transportation and other media transportation. Generally, the internal and external two-layer welding penetration technology is used, and the quality of the weld is also ensured. In the welding process, all kinds of defects, such as cracks, pores and scars can not appear. After the welding is completed, the strength of the weld must be able to continue to operate without leakage.
In order to improve the efficiency of pipeline transportation, wear-resistant ceramic elbows and nozzles can be applied in pulverized coal pipelines. The thermal expansion coefficient of these ceramic elbows and pipes is the same as that of powder pipes, and will not suffer from expansion and collapse problems due to temperature and flow washing. In addition, the installation of wear-resistant ceramics should be tightly fitted to the wall thickness to improve wear resistance. The smooth surface of the ceramic can reduce the resistance of the pipeline and improve the conveying capacity.
For large-diameter pipes, ceramic liner paste is generally used to install wear-resistant ceramic pipes, and the shape of the lining ceramic can be selected according to the actual working environment, such as selecting the patch wear-resistant ceramics or welding wear-resistant ceramics according to the temperature, to ensure that the temperature will not have too much impact on the pipeline. For small diameter pipes, ceramic rings can also be selected as pipe liners for easy installation.
In practical application, common wear-resistant ceramic pipes are mainly used in metallurgy, thermal power, steel, cement and other fields of equipment, especially subjected to strong powder washing or slurry abrasion serious equipment. For example, wear-resistant ceramic pipes can be selected for coal mill export pipes, smelter dust removal equipment, air pipe elbows, coal transport and ash transport systems. For equipment under high temperature conditions, wear-resistant ceramic pipes can also be used as a good high-temperature pipe lining.
Wear-resistant ceramic pipe is more and more common in modern industry, it has the characteristics of wear-resistant, corrosion resistance and heat resistance, which can significantly increase the service life of equipment and improve the efficiency of equipment transportation. With the development of technology, the research and application of wear-resistant ceramic pipes still have great prospects for development, and also bring more convenience and economic benefits to the industrial field.
