Alloy steel pipes are mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. They are made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. , by hot rolling (extrusion, expansion) or cold rolling (drawing).

It is mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless and heat-resistant seamless steel pipes for steam boiler pipes with high pressure and above.

The material of the 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.

The big gest advantage of alloy steel pipe can be 100% recycled, 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, my country's consumption of alloy pipes accounts for only half of the total steel volume in developed countries. The expansion of the use of alloy pipes provides a broader space for industry development. According to the research of the expert group of the Alloy Pipe Branch of the China Special Steel Association, the demand for high-pressure alloy pipe long products in my country will increase by 10-12% annually in the future. Alloy pipe is defined by steel pipe according to the production material (that is, material), as the name suggests, is pipe made of alloy; while seamless pipe is defined by steel pipe according to the production process (seamless and seamless), the difference from seamless pipe is Seam pipes, including longitudinal welded pipes and spirals.

Seamless steel pipes are perforated from a whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes.
