HR：hot rolled CW：cold worked SR：stress relieved A：annealed N：normalized HF：hot rolling Seamless steel pipe manufacturing process. According to its manufacturing process, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold drawn seamless steel pipes, punching and drawing seamless steel pipes, vertical extrusion seamless steel pipes. The first two processes are to produce general diameter seamless steel pipes, with a diameter generally between 8-406 and a wall thickness generally between 2-25; The latter two are the production of large-diameter thick walled seamless steel pipes. The diameter of seamless steel pipes is generally between 406-1800 and the wall thickness is between 20mm and 220mm. According to its purpose, it can be divided into seamless steel pipes for structural use, seamless steel pipes for fluid use, seamless steel pipes for boilers, seamless steel pipes for petroleum pipelines.
