LSAW Steel Pipe

　　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 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 ...

　　Alloy steel pipe is a kind of seamless steel pipe , its performance is much higher than the general seamless steel pipe , because this steel pipe inside containing Cr, high temperature resistance, low temperature, corrosion-resistant performance of other non-pipe joints not match, so the more extensive use of alloy tube in the petroleum, aerospace, chemical, electric power, boiler, military, and other industries. 　　The main use of alloy steel pipe used in power plants, nuclear power, high-pressure boiler, high temperature superheater and re-heater high pressure and high temperature piping and equipment, it is made ??of high quality carbon steel, alloy structural steel and heat-resistant stainless steel material, hot-rolled (extrusion, expansion) or cold-rolled (pull) made??. 　　The biggest advantages of alloy steel pipe 　　Can be 100% recycled, environmentally friendly, energy-saving, resource conservation, national strategy, national policy to encourage the expansion of the fiel...
