High Temperature 8 Inch Seamless Steel Pipe Astm A335 P11 P91 P12 St52 0


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.
