Seamless tube
Seamless steel pipe has a hollow cross section, a large number of used for conveying fluid pipelines, such as conveying oil, natural gas, gas, water and some solid materials pipelines. Is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used with steel pipe manufacturing annular parts, such as can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, etc., has been widely used to make steel pipe. Standing resource material: 10#, 20#, 35#, 45#, 16Mn, 27SiMn, 40Cr, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo, 45Mn2, etc.
