Ceramic pipe with conventional steel, wear-resistant alloy steel pipe, cast stone and plastic pipe, steel pipe and other rubber has the essential difference. Ceramic 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 carbon steel pipe corundum corundum wheel wear layer can be put away. Wear resistant ceramic 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 hardness of 7. Rare high chromium wear-resistant alloy tube or a Vickers hardness of about 400 (Rockwell hardness of about 50); lack of corundum hardness third. So wear-resistant alloy steel pipe, cast pipe wear both by composition and organization, but also by the thickness of the ceramic pipe abrasion resistance compared to them, has been a qualitative leap.
Ceramic-lined carbon steel pipe is the use of SHS - centrifugal method of manufacturing the ceramic pipe corundum melting point 2045 Centigrade, corundum layer and the steel layer structure due to process special reasons, the stress field is also special. Ceramic layer at room temperature compressive stress, steel layer subjected to tensile stress, the two opposites, into a balanced whole. Only the temperature rises above 400 Centigrade, since the thermal expansion coefficient between the two, the new stress field generated by the thermal expansion of the ceramic pipe and the stress field in the presence of the original offset each other, so that both the ceramic layer and the steel layer is free equilibrium. When the temperature rises to 900 Centigrade to ceramic-lined carbon steel pipe into the water Ling, repeated immersion times, the composite layer does not crack or crack, showing the common ceramic unparalleled thermal shock resistance. This performance would be useful in engineering construction, because of its outer layer of steel, coupled with the inner temperature is not cracked in the construction of the flanges, the purge port, explosion doors can be welded directly to the welding method can also be used connection, than wear and cast stone pipe, wear resistant steel pipe, rare earth abrasion steel, bi-metal composite pipe, steel pipe, steel rubber pipe in construction can not easily welded or soldered better. Ceramic-lined carbon steel pipe good resistance to mechanical shock resistance, while during transportation, installation and beat two weight bracket bent, not broken off the composite layer.
Ceramic-lined carbon steel pipe with high wear resistance, anti-erosion ability of the fluid. In a wind pipe, pipe wear fastest, ceramic-lined carbon steel pipe elbow abrasion wear resistance than thick steel elbow increased more than five times. In practice, the use of ceramic-lined carbon steel pipe 1-2 years after opening observe and measure, the composite layer no significant wear or fall off, the unit of the same size and length of the pipeline, the ceramic-lined carbon steel pipe weighs only wear resistant steel pipe or bimetallic composite pipe is about 1/2, its construction cost is per meter 30-40% lower, only cast stone weight steel pipe and rare wearable 2/5 or so per meter lower than 20% of the project cost. Ceramic-lined carbon steel pipe corrosion or high temperatures in use, its price is only stainless steel pipe, a fraction of the nickel-titanium tubes.
