Alloy steel pipe is mainly used in power plant, nuclear power, high pressure boiler, high temperature superheater and reheater and other high pressure and high temperature pipeline and equipment, it is made of high quality carbon steel, alloy structure steel and stainless heat-resistant steel material, by hot rolling (extrusion, expansion) or cold rolling (pull).
The biggest advantage of Alloy Steel pipe is that it can be recycled 100%, which is in line with the national strategy of environmental protection, energy saving and resource saving. The national policy encourages the expansion of the application field of high pressure Alloy pipe.At present, the alloy tube consumption in China accounts for only half of the total steel consumption in developed countries. The expansion of the alloy tube use field provides a broader space for the development of the industry.According to the research of the expert group of alloy Pipe Branch of China Special Steel Association, the demand for high pressure alloy pipe in China will increase by 10-12% annually in the future.Alloy pipe is steel pipe according to the production of material (that is, material) to define, as the name implies is alloy pipe;And seamless pipe is steel pipe according to the production process (seam seamless) to define, distinguished from seamless pipe is seam pipe, including straight seam welding pipe and spiral pipe.
The material of alloy tube is roughly as follows:
16-50Mn, 27SiMn, 40Cr, 12-42CrMo, 16Mn, 12Cr1MoV, T91, 27SiMn, 30CrMo, 15CrMo, 20G, Cr9Mo, 10CrMo910, 15Mo3, 15CrMoV, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo, etc.
