Cov kev qhia tshwj xeeb ntawm API 5L X52 feem ntau yog raws li hauv qab no:
Tube txoj kab uas hla:
Seamless yeeb nkab: Sab nraud txoj kab uas hla feem ntau yog nyob nruab nrab ntawm 21.3 hli thiab 1067 hli (xws li 1/2 "mus rau 42" hauv nti).
Hluav taws xob tsis kam welded yeeb nkab (ERW): Lub taub sab nraud tuaj yeem ncav cuag li 609.6 hli (24 ntiv tes).
Ntev seam submerged arc welded yeeb nkab (LSAW): Lub taub sab nraud tuaj yeem ncav cuag li 1422.4 hli (56 ntiv tes).
Kauv submerged arc welded yeeb nkab (SSAW): Cov kab sab nraud tuaj yeem ncav cuag li 2540 hli (100 nti).
Phab ntsa thickness:
API 5L X52 tuaj yeem tsim ntau yam ntawm phab ntsa thickness specifications, feem ntau ntawm 2 hli mus rau 150 hli. Cov phab ntsa tshwj xeeb siv yuav tsum tau txiav txim siab raws li qhov sib txawv ntawm daim ntawv thov scenarios. Piv txwv li, kev siv cov kav dej zoo tib yam tuaj yeem siv cov phab ntsa tuab dua, thaum cov kav hlau tuab tuab yog xav tau rau lub sijhawm uas muaj lub zog siab thiab kev ua haujlwm siab.
Ntev:
Muaj ob hom kev ruaj khov ntev thiab qhov ntev sib txawv. Ntev ntev ntev xws li 6.1 meters (20 feet), 12.2 meters (40 ko taw), thiab lwm yam; qhov tsis-taw ntev yog txiav txim siab raws li qhov xav tau tiag tiag thiab kev tsim khoom.
Daim ntawv kawg:
Qhov kawg tuaj yeem yog qhov kawg, lossis nws tuaj yeem ua tiav rau hauv qhov kawg bevel, threaded kawg lossis lub qhov (socket) kawg raws li qhov yuav tsum tau ua kom tau raws li qhov sib txawv thiab kev teeb tsa.
Qib steel thiab qib zoo:
Qib steel: Qhov tsawg kawg nkaus tawm lub zog yog 52200 phaus ib square inch (txog 360 MPa), uas belongs rau cov qib steel tshwj xeeb hauv API 5L tus qauv.
Qib zoo: suav nrog PSL1 thiab PSL2. PSL2 feem ntau yog nruj dua PSL1 hais txog cov tshuaj muaj pes tsawg leeg, txhua yam muaj zog, toughness, thiab lwm yam. Piv txwv li, cov ntsiab lus ntawm sulfur, phosphorus thiab lwm yam ntsiab lus yog nruj dua los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov yeeb nkab steel.
