Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore.It is inserted into a well bore and cemented in place to protect both subsurface formations and the well bore 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.

Well Casing serves as well sidewall. Standards and Technical Conditions for Supply:API Spec 5CT ISO13680 Grade: J55, K55, N80-1,N80-Q, L80-1, L80-9Cr,L80-13Cr,C95, P110. Tread types: NUE, EUE, VAM, STC, LTC, BTC, special clearance, XC,VAM TOP,NEW VAM.

Oil Casing Pipe: Casings are used for fixing the well wall or down hole, which have wide diameters, can be divided into conductor casings, technical casings and Oil casings.
