Alloy steel pipe is mainly used in power plant, nuclear power plant, high pressure boiler, high temperature superheater and reheater, etc. Alloy steel pipe in English (Alloy steel pipe) the greatest advantage can be 100% recovery, in line with the national strategy of environmental protection, energy saving, resource saving, national policy to encourage the expansion of high-pressure alloy pipe applications. At present, the proportion of alloy pipe consumption in total steel in China is only half of that in developed countries, and the expansion of alloy pipe use field provides a broader space for the development of the industry. According to the research of the expert group of the alloy pipe branch of China Special Steel Association, the demand for high pressure alloy pipe long material in China will increase by 10-12% per year in the future. Alloy pipe is defined by steel pipe according to production material (that is, material), as the name implies is alloy pipe, and seamless pipe is defined by steel pipe according to production process (seamless), which is different from seamless pipe is sewn pipe. Including straight seam welded pipe and spiral pipe. Alloy pipes have hollow sections and are used in large quantities to transport fluids, such as oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel pipe has light weight when bending and torsion strength is the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with alloy steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve and so on. At present, steel pipe has been widely used to manufacture. Alloy steel pipe is also an indispensable material for all kinds of conventional weapons, barrel, barrel and so on must be made of steel pipe. Alloy steel pipe can be divided into circular pipe and special-shaped pipe according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most of the steel pipe is a circular pipe.
