  Oil casing pipe is a seamless steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion. Each well will use several layers of casing according to different drilling depths and geological conditions. After casing is run down, cement is used to cement the well. It is different from tubing and drill pipe and cannot be reused. It is a disposable material. Therefore, the casing consumption accounts for more than 70% of all oil well pipes. The casing can be divided into: casing, surface casing, technical casing and oil layer casing according to the usage.
  L80 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and transaxial pressure placed on it while running downhole.
