Casing is used for lining the complete borehole which has been dug into the ground to procure olil Similar to the drill ipe, the oil well casing pipe is also subjected to axial tension, therefore they are required to be made from high-quality strong steel material. OCTG casing is large diameter pipe which are held in place in the borehole using cement.
