Ceramic-lined pipe is the use of SHS – Manufacturing centrifugation, the melting point of alumina ceramic pipe in 2045 ℃, alumina layer and the steel layer structure due to process special reasons, the stress field is also special. At room temperature ceramic layer compressive stress, tensile stress by steel layer, the two opposites, into a balanced whole. Only the temperature rises above 400 ℃, both due to the thermal expansion coefficient is not the same, the new stress field generated by the thermal expansion of the ceramic and steel in the presence of the original stress field cancel each other, so that both the ceramic layer and the steel layer is in free equilibrium. When the temperature rises to 900 ℃ Ling ceramic lined steel pipe placed inside the water, repeated immersion times, the composite layer does not crack or split, showing ordinary ceramic unparalleled thermal shock resistance. This performance in the construction of great use, because of its outer layer is made of steel, coupled with the inner temperature does not crack in the construction of the flange, purge port, explosion-proof doors can be welded directly to the welding method can also be used connection, than wear and cast stone pipe, wear steel pipe, wear-resistant steel rare, double metal composite pipe, steel pipe, steel rubber tube in the construction can not be easily welded or soldered better. Ceramic Lined resistance to mechanical shock resistance or, in between the transportation, installation and beat two brackets weight bending deformation, not broken off the composite layer.
Ceramic-lined pipe with traditional steel, wear-resistant alloy steel pipe, cast stone and steel-plastic pipe, steel pipe and other rubber has essential difference. Ceramic outer layer is steel pipe inner corundum. Corundum layer up to 100-1500 Vickers hardness (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 adhesive wheel made of corundum performance. Now is still a variety of corundum grinding wheel grinder cut hardened steel main wheel. Ceramic pipe layer in the corundum corundum grinding wheel wear out. Wear-resistant ceramic pipe corundum mainly by a few millimeters thick inner layer, the Mohs hardness of 9, second only to diamond and silicon carbide, oxide in all, it is the highest hardness.
Ceramic-lined pipe with high wear resistance, anti-erosion ability fluid. In a wind pipe, pipe wear fastest, ceramic-lined steel pipe elbow thick abrasion wear resistance than steel elbow is more than 5 times.
