Main advantages of P11 steel pipe

Recyclable, in line with the national strategy of environmental protection, energy conservation, and resource conservation, national policies encourage the expansion of high-pressure P11 alloy. At present, the consumption of P11 alloy pipes in China accounts for only half of the total steel consumption compared to developed countries. The expansion of the use of P11 alloy pipes provides a broader space for industry development. According to the research of the P11 Steel Pipe Branch of China Special Steel Association, the average annual growth rate of demand for high-pressure P11 steel pipes in China can reach 10-12% in the future.

Chemical composition of p11 steel pipe: c:0.05~0.15, mn:0.30~0.60, p:0.025, s:0.025, si: 0.50~1.00, cr:1.00~1.50, mo: 0.44~0.65

P11 steel pipe belongs to heat-resistant alloy structural steel and follows the material grade specified in ASTM A335/A335M-2015a (ferritic seamless source steel pipe for high temperature pipelines). The composition of this material is 1.25Cr-0.5Mo-Si
