Ceramic-lined steel pipes are a new line of wear-resistant products produced by the self-propagating
thermite-centrifugal technique. The research and development of the pipes were emphasis projects of the Eighth and Ninth Five-year Plan Periods. So far, only China manufactures the ceramic-lined steel pipes on an industrial scale.
The composite pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500℃. The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3spreads on the inside wall of the steel pipe under the influence of a centrifugal force, then solidifies, so the ceramic layer has high density and smooth surface and bonds to the steel pipe.
The ceramic-lined steel pipes have numerous exceptional properties including good resistance to abrasion, heat, mechanical and thermal shocks. The pipes are easy to weld and fixing. They are very suitable for the transport of abrasive materials and thus can replace cast ceramic pipes, alloy pipes, and resin-lined steel pipes. They have a wide variety of application in mining, power plants, water conservation and metallurgical, coal, petroleum, and building material industries. In actual use in mining, power plants, and the metallurgical factories in recent years, the service life of the composite pipes is more than 20 times longer than common steel pipes.
The scientists of our companies began their research work on ceramic-lined steel pipes in 1989, which was the frist in China. The Ministry of Metallurgical Industry and the Ministry of Light Industry appraised our study work in 1992, and National Council of Light Industry evaluated the trial-production in 1994. As a project supported by the National Advanced Materials Committee (subject No. 715-24-2103-04), our work was examined and accepted by the Committee in 1995, and received the highest grade "A". The Committee reported that our work on ceramic-lined steel pipes "made this technique reach advanced international level for the 90's". We continue to have the support from the "863" Plan during the Ninth Five-year Plan Period (subject No. 715-009-0130).
Our product won the first-grade prize for excellence of a new product and a second-grade prize for science & technology progress awarded by National Council of Light Industry in 1995 and 1996, respectively.
