1. Hot-rolled (extrusion seamless steel pipe): round tube perforation → → heating → three-roll rolling, rolling or extrusion → detached → sizing (or reducing) → cooling → straightening → hydrostatic test (or testing) → mark → storage of raw material is rolled seamless round tube, tube embryos to go through a cutting machine cutting a length of about 1 meter blank, and by conveyor belt to the furnace heating. The billet is fed into the furnace is heated to a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is the key issue. After a round tube came out to go through the pressure punching machine wear air. Generally more common punch is tapered roller punching machine, punching machine such high production efficiency, product quality, perforated expanding capacity, can be worn a variety of steels. After perforation, round tube has been three-roll rolling, rolling or extrusion. To post extrusion detached sizing. Sizing high-speed rotary cone drill bit through the perforated steel embryo formed steel.

2. Cold drawn (rolled) seamless steel pipe: round tube perforation → heating → → → annealing → pickling → Heading oiled (copper) → multi-pass cold drawn (cold) → blank tube → heat treatment → straightening → hydrostatic test (testing) → mark → storage. Cold drawn (rolled) seamless steel pipe rolling method than hot-rolled (extrusion seamless steel pipe) complex. The first three steps of their production process is basically the same. Differs from the fourth step begins, round tube empty after playing, to begin with, annealing. After annealing to use a special acidic pickling liquid. Pickled, oiled. Then followed through many times of cold drawn (cold) and then blank tube, special heat treatment. After the heat treatment, it must be straightened.
