API 5CT Tubing Applications
OCTG Tubing in API 5CT is mainly used to transport oil and gas well drilling and oil and gas. It includes oil drilling pipe, oil casing, pump tubing. Oil drill pipes are mainly used to connect the drill collar and drill and pass drilling power. Oil casing is mainly used to support the borehole when drilling and after completion, to ensure that the conduct and completion of the drilling process after the normal operation of the entire oil wells. The pipeline is mainly used in pumping oil and gas at the bottom transported to the ground.
