X42 seamless kab yeeb nkab yog ib qib uas tau teev tseg raws li API 5L tus qauv, cais raws li PSL1, thiab tsim nyog rau kev thauj mus los dav dav.
Lub npe ntawm X42 seamless kab yeeb nkab ua raws li API 5L tus qauv. Ntawm no, "X" qhia tias cov yeeb nkab yog ua los ntawm cov hlau, thiab "42" sawv cev rau nws qhov kev ua haujlwm tsawg kawg nkaus, ntsuas hauv kilopounds ib square inch (ksi), uas yog kwv yees li 290 megapascals (MPa) hauv International System of Units. Qib no xav kom cov kab yeeb nkab tsis yog tsuas yog lub zog xwb tab sis kuj zoo weldability thiab formability kom tau raws li cov kev xav tau ntawm qhov ntev - kev tsim kho kav dej.
X42 seamless kab yeeb nkab yog muaj nyob rau hauv ntau yam ntawm sab nraud diameters, feem ntau los ntawm 1/8 nti mus rau 26 ntiv tes, nrog rau tej qhov ntau thiab tsawg yuav raug xaiv raws li engineering tsim. Phab ntsa tuab feem ntau tau teev tseg raws li API 5L tus qauv, nrog rau cov series xws li cov qauv phab ntsa tuab, ntxiv - phab ntsa tuab, thiab cov phab ntsa tshwj xeeb. Kev sib xyaw ntawm sab nraud txoj kab uas hla thiab phab ntsa tuab txiav txim siab cov yeeb nkab lub siab- cov kabmob muaj peev xwm, uas yuav tsum tau suav thiab xaiv raws li qhov tsis xws li kev thauj khoom siab thiab kev faus neeg.
Tus qauv ntev ntawm X42 seamless kab yeeb nkab feem ntau yog nruab nrab ntawm 6 mus rau 12 meters, tab sis nws tseem tuaj yeem ua rau kev cai ntev raws li cov neeg siv khoom xav tau. Kev txiav txim siab ntev yuav tsum xav txog yam xws li kev txwv kev thauj mus los, ntawm - qhov chaw tsim kho, thiab kev ua haujlwm vuam. API tus qauv muaj cov kev cai meej ntawm qhov sib txawv ntawm qhov ntev, feem ntau yuav tsum muaj qhov ntev ntev tsis pub tshaj +100mm/-0mm.
