Looking for some materials
Thread Content
I’m looking for some standards regarding pipe materials, as well as standards for various pipe substances. For example, what is P11, and what is 347.
At present, the proportion of P11 steel pipes in China’s total steel consumption is only half that of developed countries; the expansion of the areas where P11 steel pipes are used provides broader opportunities for the development of this industry. According to research by the P11 Steel Pipe Branch of the China Special Steel Association, the annual growth rate in demand for long P11 steel pipes for high-pressure applications in China is expected to reach 10–12% in the future. p11_Baidu Baike http://baike.baidu.com/link?url=2eKZ4VsG1rM0b6dM-KGubCpgpPJQZv5gzqxw_GSJ-bdHCVJh25REtDrEQDwOBVYk4YvwEdpTfNoPr-pHdJqtAq
Consult ASME Standard Volume 2, Section A. . .
A335 P11 is a material from abroad; it consists of 1.25Cr0.5Mo and is a chromium-molybdenum alloy steel. ASTM A335 corresponds to the standards A312 and 347, which pertain to stainless steels. 06Cr18Ni11Nb。 ASTM A312 is a standard. There is other stainless steel inside as well
