API 5CT K55 Carbon OCTG Steel Pipe Tube Oil Casing Tube

API 5CT K55 Carbon OCTG Steel Pipe Tube Oil Casing Tube The Oil casing is used to support the well bore of oil and gas wells to ensure the normal operation of the whole well after drilling and completion. Each well should use several layers of casing according to different drilling depth and geological conditions. Cement cementing is used after casing goes down. It is different from tubing and drill pipe. It can not be reused. It belongs to disposable consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well tubes. Casing can be divided into: conduit, surface casing, technical casing and reservoir casing.
