Seamless steel pipe manufacturing process. According to its manufacturing process, seamless steel pipes are divided into hot-rolled seamless steel tubes, cold-drawn seamless steel tubes, punched, drawn seamless steel tubes, and vertical extruded seamless steel tubes. The caliber is generally 8-406, and the wall thickness is generally 2-25; the latter two are the production of large-diameter thick-walled seamless steel pipes, which are generally 406-1800, and the wall thickness is
20mm-220mm. According to its use, it can be divided into seamless steel tubes for structural use and seamless steel tubes for fluid
