Roj Pipe Kab API 5L Steel Kab Yeeb Nkab Plate
Lus piav qhia luv luv:
Pipeline steel yog ib hom hlau phaj siv rau cov kav dej, feem ntau yog siv hauv kev tsim cov kav dej rau cov roj thiab cov nkev, nrog rau cov thee thiab cov khoom siv hauv tsev slurries.Cov hlau tsis tsuas yog yuav tsum tau muaj zog compressive, tab sis kuj yuav tsum muaj qhov kub thiab txias toughness thiab zoo weldability.
Rau qhov yog theem ntawm kev npau suav ntawm peb cov neeg ua haujlwm!Txhawm rau tsim kom muaj kev zoo siab, sib koom ua ke thiab ntau tus neeg ua haujlwm tshaj lij!Txhawm rau kom ncav cuag kev sib koom ua ke ntawm peb cov kev cia siab, cov neeg xa khoom, cov zej zog thiab peb tus kheej rau Roj Yeeb KabAPI 5L Steel Kab Yeeb Nkab Plate, Nco ntsoov tias koj yuav tsum tsis txhob yig hu rau peb yog tias koj txaus siab rau peb cov khoom.Peb ntseeg tau tias peb cov khoom yuav ua rau koj txaus siab.
Rau qhov yog theem ntawm kev npau suav ntawm peb cov neeg ua haujlwm!Txhawm rau tsim kom muaj kev zoo siab, sib koom ua ke thiab ntau tus neeg ua haujlwm tshaj lij!Txhawm rau kom muaj kev sib koom ua ke ntawm peb lub zeem muag, cov neeg xa khoom, lub zej zog thiab peb tus kheej rauAPI 5L Steel Kab Yeeb Nkab Plate, Peb tau txaus siab los muab peb cov khoom thiab cov kev daws teeb meem rau txhua tus kiv cua pib thoob plaws ntiaj teb nrog peb cov kev pabcuam hloov tau yooj yim, ceev nrawm thiab cov txheej txheem tswj hwm nruj tshaj plaws uas ib txwm pom zoo thiab qhuas los ntawm cov neeg siv khoom.
Niaj hnub nimno pipeline steel yog cov pa roj carbon tsawg lossis ultra-low-carbon microalloyed steel, uas yog cov khoom lag luam nrog cov ntsiab lus siab thiab cov nqi ntxiv.Feem ntau ntawm kev ua tiav thev naus laus zis tshiab hauv thaj chaw metallurgical hauv 20 xyoo dhau los tau siv rau kev tsim cov raj xa dej.Txoj kev loj hlob ntawm pipeline engineering yog cov yeeb nkab loj txoj kab uas hla, high-pressure nplua nuj roj tsheb thauj mus los, siab txias, siab corrosion siv ib puag ncig, thiab subsea pipeline phab ntsa thickness.Yog li ntawd, niaj hnub pipeline steel yuav tsum muaj lub zog siab, tsis tshua muaj Bauschinger nyhuv, siab toughness thiab brittleness kuj, tsawg weld carbon cov ntsiab lus thiab zoo weldability, thiab kuj rau HIC thiab H2S corrosion.
Cov yeeb nkab steel phaj yog siv los tsim cov welded kab kav, vim seamless kab yeeb nkab yog ua los ntawm puag ncig bar, tsis steel daim hlau.Qhov nruab nrab tuab phaj feem ntau yog siv los tsim cov phab ntsa tuab ncaj seam welded yeeb nkab, thiab cov hlau coil yog siv los tsim hluav taws xob tiv thaiv welded (ERW) yeeb nkab thiab spirally submerged arc welded (SSAW) yeeb nkab.Niaj hnub no, ntau thiab ntau tus neeg xav tau cov kav dej steel phaj los tsim cov kav dej vim tias cov phaj hlau tuaj yeem siv los tsim cov kav dej loj dua, ntxiv rau, tus nqi ntawm cov kav dej feem ntau qis dua cov kav dej seamless.
Kab yeeb nkab steel phaj yog cov khoom siv tseem ceeb rau kev tsim cov ERW kab yeeb nkab, LSAW kab yeeb nkab, SSAW kab yeeb nkab, uas yog siv rau hauv cov yeeb nkab kab kev tsim kho hauv cov roj, roj thiab dej thauj, nws tuaj yeem siv rau hauv kev tsim cov kua dej sib kis.
Tsis tshua muaj kub ntawm arctic, kev kub ntxhov hauv dej hiav txwv sib sib zog nqus, cov kua qaub tshaj tawm: txawm tias qhov kev mob hnyav tshaj plaws tsis muaj qhov tsis zoo rau peb cov kab hluav taws xob.Linepipe daim hlau tuaj yeem ua haujlwm hauv qhov tob txog li 2,800 meters hauv qab dej hiav txwv.
Peb kuj muab yob-bonded clad offshore qauv steel phaj nrog corrosion-resistant cladding rau qhov xav tau siab tshaj plaws hauv qaub-gas daim ntawv thov.Raws li ib tug kws tshaj lij nyob rau hauv niaj hnub thermo mechanical dov tshuab nrog ceev cua txias, peb yog cov thawj coj hauv ntiaj teb kev lag luam.
