API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries. Casing and Tubing is a kind of OCTG pipe.
API 5CT Tubing is used to carry petroleum from the well’s depths to the surface. This is the third phase of the wellbore process. Oil and gas occasionally self-elevate to the surface; however, pumps are typically required to bring the fluids to the surface. Besides the 4 1/2-inch diameter, tubing is normally smaller in diameter than the casing. Consequently, the tubing must be affixed to external support structures, such as a rig or platform, in order to prevent collapse due to pressure differentials.
