Kev xeem rau API 5CT N80 OCTG
Txhawm rau kom ua tau zoo thiab ua raws li, N80 tau dhau los ua ntau qhov kev sim:
Tshuaj ntsuam xyuas:Txheeb xyuas P, S, thiab cov khoom sib xyaw.
Tensile Test:Ua kom muaj txiaj ntsig thiab lub zog tensile poob hauv 80k-110k psi ntau.
Flattening Test:Kev tshuaj xyuas cov ductility thiab muaj peev xwm weld tsis xws luag (rau ERW yeeb nkab).
Hydrostatic Test:Txhua qhov sib koom ua ke yog nias kom ntseeg tau tias tsis muaj qhov xau.
NDT (Tsis yog -Kev Ntsuas Kev Ua Phem):
Ultrasonic (UT)los yogSib nqus Particle (MPI)nrhiav cov kab nrib pleb thiab phab ntsa thickness variations.
Hardness Test (Tshwj xeeb rau N80-Q):Txhawm rau txheeb xyuas qhov ua tiav ntawm Quench & Temper txheej txheem.
Impact Test (Charpy V-Notch):Yuav tsum tau rau N80-Q kom toughness; xaiv tau / ntxiv rau N80-1.
Drift Test:Hla ib lub mandrel los ntawm cov yeeb nkab kom ntseeg tau tias lub taub sab hauv yog qhov tseeb rau cov cuab yeej.

FAQ
Dab tsi yog qhov txawv ntawm N80 thiabL80?
N80 thiab L80 yog ob qib casing / tubing raws li API SPEC 5CT tus qauv, nrog qhov sib txawv tseem ceeb hauv kev tswj lub zog, kev tiv thaiv corrosion, thiab siv tau rau ib puag ncig. L80 muaj zog ruaj khov, muaj chromium, thiab muaj kev tiv thaiv rau hydrogen sulfide corrosion, ua rau nws haum rau cov av qaub; N80 yog siv nyob rau hauv cov pa nruab nrab - qhov tob tob, muaj tus nqi qis, tab sis tsis muaj zog corrosion kuj.
Dab tsi yog qhov tshiab ntawm API 5CT?
Qhov tsab xov xwm tshiab kawg ntawm API 5CT yog 11th Edition, luam tawm thaum Lub Kaum Ob Hlis 2023. Qhov tsab xov xwm no hloov kho tsis yog -kev kuaj kev puas tsuaj (NDT) cov cai, nthuav dav cov khoom lag luam, thiab tsim kom muaj cov qauv nruj dua rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev tswj xyuas zoo siv tau rau hauv cov roj thiab roj extraction.
