Dab tsi yog qhov tuab ntawm API 5CT casing

API tag nrho ntawm cov tubing thiab casing feem ntau yog hais txog cov kav hlau uas ua raws li American Petroleum Institute's API SPEC 5CT tus qauv, feem ntau yog siv rau kev rho tawm cov peev txheej xws li roj thiab nkev. Cov tubing yog siv los rho cov roj los yog cov pa roj los ntawm cov roj qhov dej. Lub casing ua hauj lwm raws li phab ntsa wellbore rau roj thiab roj qhov dej.
