Ang casing ay isang malaking diameter na tubo na nagsisilbing structural retainer para sa mga dingding ng mga balon ng langis at gas, o well bore. Ito ay ipinapasok sa isang well bore at sementado sa lugar upang maprotektahan ang parehong subsurface formations at ang well bore mula sa pagbagsak at sa hayaang umikot ang likido sa pagbabarena at maganap ang pagkuha.Ang Steel Casing Pipe ay may makinis na pader at pinakamababang lakas ng ani na 35,000 psi.

Nagsisilbi rin ang Well Casing sa sidewall.Mga Pamantayan at Teknikal na Kundisyon para sa Supply:API Spec 5CT ISO13680 Grade: J55, K55, N80-1,N80-Q, L80-1, L80-9Cr,L80-13Cr,C95, P110.Mga uri ng tread: NUE, EUE, VAM, STC, LTC, BTC, espesyal na clearance, XC,VAM TOP,NEW VAM.

Oil Casing Pipe: Ang mga casing ay ginagamit para sa pag-aayos ng well wall o down hole, na may malawak na diameters, ay maaaring nahahati sa conductor casings, technical casings at Oil casings.

Mga Gamit: Nagsisilbi rin ang Well Casing sa sidewall.
