Seamless steel pipes are generally made by hot rolling or cold rolling of high quality carbon-bonded steel 16Mn, 5MnV or alloy steel 40Cr, 30CrMnSi, 45Mn2 and 40MnB. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transmission pipelines. Seamless tubes made of medium carbon steel, such as 45, 40Cr, are used to manufacture mechanical parts,such as stress parts of automobiles and tractors.Hot-rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
