Ceramic lined composite steel pipe with conventional steel, wear-resistant alloy steel pipe, cast stone and plastic pipe, steel pipe and other rubber has the essential difference. Ceramic lined composite steel pipe is steel outer and inner corundum. Corundum layer Vickers hardness 1100-1500 (Rockwell hardness of 90-98), the equivalent of tungsten-cobalt hard gold. High wear resistance than carbon steel pipe more than 20 times, it is much more superior than the usual bonding together corundum wheel performance. Now it is still a variety of corundum grinding wheel grinder cut hardened steel main wheel. Ceramic lined composite steel pipe corundum corundum wheel wear layer can be put away. Wear resistant Ceramic lined composite steel pipe corundum layer may be formed mainly by a few millimeters thick, a Mohs hardness of 9, second only to diamond and silicon carbide, all oxides, which is the highest hardness. ¯ pipe and the component is only about 20% alumina, most of SiO2, SiO2 Mohs
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
