API 5CT standardizes casingthiab tubing rau cov roj qhov dej hauv kev lag luam roj thiab roj, thiab teev cov txheej txheem kev xa khoom rau cov kav dej steel, coupling blanks, coupling cov ntaub ntawv thiab cov khoom siv ntxiv.
Ntawm lawv, N80 qib yog ib hom API 5CT roj casing, uas yog tsuas yog siv nyob rau hauv cov roj qhov dej nrog ntau yam kawg kev sib txuas, xws li tsis-thickened xaus los yog sab nraud thickened xaus. N80 qib oilfield casing muaj ob hom: N80-1 hom thiab N80-Q hom. Ob hom muaj tib yam tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab, tab sis muaj qhov sib txawv ntawm txoj kev kho cua sov. N80-1 steel yeeb nkab txais yuav normalizing + tempering kho, thaum N80-Q steel yeeb nkab txais quenching + tempering kho. Vim muaj qhov sib txawv ntawm txoj kev kho cua sov, lub zog tawg thiab lub zog sab hauv ntawm N80-Q yog sib npaug siab dua li ntawm N80-1.
N80 roj av casing muaj cov cuab yeej zoo heev, nws lub zog tensile tsis tsawg dua 689MPa, thiab nws lub zog tawm los ntawm 552 thiab 758MPa. Raws li API cov cai, muaj peb hom N80 roj casing ntev, xws li R-1 (4.88 ~ 7.62m), R-2 (7.62 ~ 10.36m) thiab R-3 (10.36. m rau ***).
