With the development of new materials and conveying technologies, they have gradually been replaced by the latest wear-resistant materials such as special ceramics. Wear-resistant ceramic pipes are composite pipe materials formed by organically combining ceramics and metals using an aluminothermic-centrifugal method. The aluminothermic-centrifugal method for preparing inner-lined ceramic steel pipes utilizes the high temperature generated by the self-heat of the reaction to melt the reaction products and separate them under centrifugal force, forming a steel pipe with an inner lining of alumina ceramics. This method boasts low energy consumption and fewer processes.
Ceramic pipes combine the high hardness, good chemical inertness of alumina, and the advantages of steel, exhibiting excellent wear resistance, corrosion resistance, heat resistance, and resistance to thermal and mechanical shock. Their lifespan is more than 15 times longer than ordinary steel pipes. The pipes are generally white.
The inner lining ceramic layer of the wear-resistant ceramic elbow is made of wear-resistant engineering ceramics, with a hardness (HRA) ≥84. Its wear resistance is more than 10 times that of high-chromium wear-resistant cast iron alloy pipe fittings. Using a 5mm thick ceramic layer, its actual wear-resistant service life will be equivalent to that of a 50mm thick wear-resistant cast steel.
Wear-resistant ceramic pipes themselves have the ability to withstand temperatures above 1200 degrees Celsius. Through reasonable design and the use of different composite methods, wear-resistant ceramic pipe fittings can operate for extended periods within a temperature range of -50℃ to 800℃, making them particularly suitable for high-temperature burners, etc.
