Casing is a large diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore in oil drilling field.
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Steel Casing Pipes have smooth wall & minimum yield strength of 35,000 psi.
