Qhov txawv ntawm X52 thiab X65 yeeb nkab yog dab tsi

Hauv kev lag luam xws li roj thiab roj tsheb thauj mus los, API 5L X52 thiab X65 kav dej muaj qhov sib txawv loj.
Hais txog cov tshuaj muaj pes tsawg leeg, cov ntsiab lus carbon ntawm X52 tsuas yog txwv rau qee qhov, thiab cov ntsiab lus manganese tsawg dua lossis sib npaug li 1.40%. Cov ntsiab lus carbon cov ntsiab lus ntawm X65 zoo ib yam li X52, tab sis cov ntsiab lus manganese tuaj yeem ncav cuag 1.65% thiab muaj ntau cov ntsiab lus alloying xws li vanadium, niobium, thiab titanium.
Nyob rau hauv cov nqe lus ntawm txhua yam khoom, qhov tsawg kawg nkaus yield zog ntawm X52 yog 360MPa thiab tensile zog yog 460MPa; Qhov tsawg kawg nkaus tawm lub zog ntawm X65 yog 450MPa thiab lub zog tensile yog 535MPa. X65 muaj lub zog ntau dua thiab tuaj yeem tiv taus siab dua thiab thauj khoom. Nws muaj peev xwm tuav tau zoo toughness nyob rau hauv uas tsis muaj kub los yog complex ib puag ncig, thiab yog tsim nyog rau cov roj thiab roj pipelines uas muaj tej yam toughness yuav tsum tau.
Yog li ntawd, hauv daim ntawv thov, X52 yog siv rau kev thauj mus los ntawm cov roj thiab roj thiab cov kua dej thiab cov khoom siv cuam tshuam txog kev ua haujlwm hauv kev lag luam tshuaj, kev tsim kho, thiab lwm yam; X65 feem ntau yog siv rau kev thauj mus los ntev thiab qhov loj ntawm txoj kab nruab nrab ntawm cov roj thiab cov roj hauv lub cev, thiab nws lub zog siab thiab tawv tawv hloov mus rau kev ua haujlwm hnyav.
Nyob rau hauv cov nqe lus ntawm vuam kev ua tau zoo, X52 muaj zoo weldability. Txawm hais tias X65 tuaj yeem welded, vim nws cov ntsiab lus carbon thiab manganese siab, cov txheej txheem yuav tsum tau tswj nruj me ntsis thaum vuam.
