China Shandong Baote metal products Co., Ltd. specializes in producing steel pipe diameter: 6mm-1200mm!
The main production processes of large-diameter seamless steel pipe in China are hot-rolled large-diameter seamless steel pipe and hot expanded seamless steel pipe. The specification of hot expanded seamless steel pipe is 325mm-1220mm, and the maximum thickness is 200mm.
Hot expanded seamless steel pipe can produce non-national standard dimensions. Hot expanded seamless pipe is what we often call hot expanded pipe. For steel pipes with low density but strong shrinkage, it is a kind of blank pipe finishing rolling process to expand the pipe diameter by cross rolling method or drawing method. It is the development trend in the international pipe rolling field to make the steel pipe thicker in a short time and produce non-standard and special seamless pipes with low cost and high production efficiency.
Application of thick wall steel pipe thick wall steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. For liquid transportation: water supply and drainage. For gas transmission: gas and steam. For structure: as pile driving pipe and bridge; Pipes for wharf, road, building structure, etc. The materials of thick walled steel pipes commonly used in China are: 10#, 20Mn, 42CrMo, 36crmo, 40Cr, 20Cr, 15CrMo, 12Cr1MoV, Q235A, Q235B, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, 16Mn, 20#, 45#, Q345, L245, L290, X42, X46, X70, X80
The company was founded in 2003. It abides by the contract and reputation. While continuously improving the competitiveness of customers through service, it has also won market praise for ourselves.
