Hot Rolled Seamless Steel Tube 28 Inch Water Well Casing Oil And Gas Carbon Seamless Steel Pipe

Cold drawing (rolling) carbon steel seamless steel tube: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → water pressure test (flaw detection) → marking → storage
Cold rolled precision seamless steel pipe (GB3639-2000) is used for precision mechanical structure, hydraulic equipment or steel sleeve of high dimensional accuracy and good surface finish of a seamless steel pipe.
