High frequency welding,hot stretch reducing,full body heat treatment and high temperature straightening"process was adopted to produce BSG-110 TT high collapse resistance oil casing.The evolution of microstructure and property of casing steel at different process stage was analyzed.The mechanical properties and corrosion resistance properties of BSG-110 TT were also tested.The results show that the dimensional accuracy,residual stress and collapse resistance of BSG-110 TT are much better than high collapse resistance seamless oil casing tube.Moreover,the used production process benefits to solve the problems of low impact toughness and poor corrosion resistance of weld zone.
