Product content
Composite ceramic steel pipe is a new type of composite material with international advanced level that has been successfully developed and firstly industrialized in the national "863" high-tech technology plan. The product is manufactured by the self-propagating high temperature synthesis method (SHS), using the aluminothermic reaction itself to exothermic melting reactants, and the separation principle of Al2O3 and Fe under the action of centrifugal force. The composite tube is corundum ceramic (AL2O3) layer from the inside to the outside. Transition layer and steel tube layer. The corundum ceramic layer is a dense corundum ceramic formed at a high temperature above 2000 °C to form a firm metallurgical bond with the steel pipe through the transition layer. It has good corrosion resistance, wear resistance, high strength, toughness, and strong resistance to mechanical shock and thermal shock. comprehensive performance. And can be turned, grinding and welding and other processing. So far, no composite material has such excellent comprehensive properties.
The ceramic layer contains more than 90% AL2O3, and the acid resistance is 96-98%, which is the same as the acid resistance of high corundum porcelain. The corrosion resistance is ten times higher than that of stainless steel, and the wear resistance is equivalent to that of tungsten-cobalt cemented carbide, which is more than ten times higher than that of steel, and can work for a long time below 900 ºC.

Note: 1.The thickness of the seamless steel pipe is 8mm, the total thickness of the ceramic layer and the transition layer is 2.5~3.5mm, the strength when the MPa ceramic inside the tube is crushed from the outside of the tube.
2.The strength when the ceramic layer is pressed out of the seamless steel pipe in the axial direction of the ceramic steel pipe.
3.The temperature range is -30~500ºC.
Ceramic lining composite Y type is used for power plant coal powder, ash slag, mine powder, tailings, backfill, coal from coal mines, concentrators, coking plant coke particles, and sintering plant materials. The service life is 15 times longer than ordinary steel pipes. Above, it can also be used for the transportation of molten aluminum and corrosive media. The thermite-centrifugal method prepares the ceramic-lined steel pipe using the high temperature generated by the reaction itself to melt the reaction products and separate them under the action of centrifugal force to form a steel pipe lined with alumina ceramics, with low energy consumption and fewer processes.
