Cov tshuaj muaj pes tsawg leeg ntawm X42 yog dab tsi?
Cov tshuaj muaj pes tsawg leeg ntawm X42 qib yuav tsum ua raws li API 5L tus qauv yuav tsum tau ua. Cov ntsiab lus carbon feem ntau tswj tau qis dua 0.28%, manganese cov ntsiab lus raug kho nyob rau hauv thaj tsam ntawm 0.90-1.35% nyob ntawm phab ntsa tuab, thiab cov ntsiab lus ntawm cov khoom tsis zoo xws li sulfur thiab phosphorus yuav tsum tau tswj nruj me ntsis. Tus qauv kuj qhia meej meej cov kev cai rau cov pa roj carbon sib npaug (CEIIW) thiab PCM qhov tseem ceeb los xyuas kom muaj kev sib tw.

Dab tsi yog Mechanical Properties ntawm X42?
Cov khoom siv ntawm X42 seamless kab yeeb nkab feem ntau suav nrog lub zog tawm los, lub zog tensile, thiab elongation. Raws li API 5L, qhov kev xav tau ntawm lub zog yuav tsum tsis pub tsawg dua 290 MPa, lub zog tensile yuav tsum nyob rau hauv thaj tsam ntawm 415-565 MPa, thiab qhov yuav tsum tau elongation txawv nyob ntawm qhov ntsuas qhov ntev. Tus qauv kuj tseem qhia txog qhov yuav tsum tau ua kom muaj zog, feem ntau xav tau Charpy cuam tshuam lub zog kom ua tau raws li qhov tseem ceeb ntawm 0 degree.

API 5L X42 Specification yog dab tsi
Sab nraud txoj kab uas hla ntawm X42 seamless kab yeeb nkab yog qhov dav heev, nrog cov kev qhia tshwj xeeb xws li 1/8 nti txog 26 ntiv tes. Qhov tshwj xeeb qhov ntev yuav tsum raug xaiv raws li kev tsim qauv engineering. Phab ntsa tuab feem ntau tau teev tseg raws li lub rooj loj hauv API 5L, nrog rau ntau yam xws li cov qauv phab ntsa tuab, cov phab ntsa muaj zog ntxiv, thiab cov phab ntsa hnyav ntxiv. Kev sib xyaw ntawm sab nraud thiab phab ntsa tuab txiav txim siab cov yeeb nkab lub siab- cov kabmob muaj peev xwm, uas yuav tsum tau muab xam raws li qhov tsis xws li kev xa khoom siab thiab kev faus neeg.
Ib qhov ntev ntawm X42 seamless kab yeeb nkab feem ntau yog 6-12 meters, tab sis nws tseem tuaj yeem txiav - rau-ntev ua raws li cov neeg siv khoom xav tau. Kev txiav txim siab ntawm qhov ntev yuav tsum xav txog kev txwv kev thauj mus los, kev tsim kho ntawm qhov chaw, thiab kev ua haujlwm vuam, thiab lwm yam. API tus qauv muaj cov kev cai meej ntawm qhov sib txawv ntawm qhov ntev, feem ntau xav kom qhov sib txawv ntawm qhov ntev tsis tshaj +100mm/-0mm.
