Ceramic lined composite steel pipe is a new composite material developed under the national high-tech technology '863' plan, leading the industrialization with international advanced level. The pipe consists of ceramic, transition layer, and steel layer from inside to outside. The ceramic layer is formed at a temperature above 2000 ℃, creating a dense steel jade porcelain through the transition layer, which forms a solid metallurgical bond with the steel pipe. It exhibits excellent corrosion resistance, wear resistance, high temperature and high strength, high toughness, comprehensive resistance to mechanical shock and thermal shock. It can also undergo turning, grinding, welding, and other processing.
