Ceramic Lined Pipes - Alumina Composite Steel, High-density Smooth Surface | Abrasion And Corrosion Resistant, Thermal Shock Resilient, Innovative Centrifugal Thermite Process

The Manufacturing Process of Ceramic Lined Pipes:
SHS (Self-propagating High-temperature Synthetic process) ceramic lined steel pipe and elbow create a new generation of abrasion and corrosion resistant engineering pipeline.The composite steel pipe is composed of three layers: ceramic, intermediate, and steel layers. The ceramic layer is formed by molten alumina at a temperature above 2500 degree. The molten alumina produced from the reaction Fe2O3+2Al=2Fe+Al2O3 spreads 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.
Abrasion Resistant Ceramic Lined Pipes have been uniformly produced by a thermite reaction induced under the influence of a centrifugal force (a Centrifugal Thermite Processa ) without any high-temperature furnace facilities. The characteristic feature of the present process for forming uniform ceramic layers is in its reaction propagation as well as the reaction heat and centrifugal force. It is very important in improving the quality of the ceramic lined pipes to find the proper conditions of the reactant and centrifugal force; the former mainly determines the produced ceramic layer quality and the latter the achievement of layer separation and the mechanical properties of the pipes. Ceramic lined tube has great resistance against corrosion, abrasion and thermal shock.
