Korpus
Korpus on suure läbimõõduga toru, mis toimib nafta- ja gaasipuuraukude seinte või puurkaevude konstruktsioonihoidjana. See sisestatakse puurauku ja tsementeeritakse kohale, et kaitsta nii maa-aluseid moodustisi kui ka puuraugu kokkuvarisemise ja lase puurimisvedelikul tsirkuleerida ja ekstraheerida.Terasest korpusega torudel on sile sein ja minimaalne voolavuspiir on 35 000 psi.
Kaevu korpus toimib ka külgseinana.Tarnestandardid ja tehnilised tingimused: API Spec 5CT ISO13680 Hinne: J55, K55, N80-1, N80-Q, L80-1, L80-9Cr, L80-13Cr, C95, P110.Turvise tüübid: NUE, EUE, VAM, STC, LTC, BTC, erikliirens, XC, VAM TOP, UUS VAM.
Õlikorpuse toru: Kaevu seina või põhjaava kinnitamiseks kasutatakse laia läbimõõduga korpuseid, mida saab jagada juhtmekesteks, tehnilisteks korpusteks ja õlikesteks.
Kasutusalad: Kaevu korpus toimib ka külgseinana.
