  • API 5CT Casing Pipe Application

    API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion well’s normal operation. Each well depending on the depth of drilling and geological conditions, use several layers of casing. After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, one-time consumable materials. Therefore, the casing consumption accounts for over 70% of all the oil well pipes. According to by usage can be divided into the sleeve pipe, surface casing, casing, and production casing.
