Nyob rau hauv lub tshav pob ntawm cov roj thiab roj tsheb thauj mus los, kauv yeeb nkab qhia tshwj xeeb zoo duaLSAW tub, uas yog feem ntau ntaus nqi rau cov yam ntxwv kev coj los ntawm nws tshwj xeeb tsim thiab ntau lawm txheej txheem.
Ua ntej ntawm tag nrho cov, txoj kev tsim ntawm kauv yeeb nkab ua rau nws muaj peev xwm siv nqaim steel sawb los tsimloj txoj kab uas hla steel yeeb nkab, uas yog ib qho tseem ceeb tshwj xeeb hauv kev thauj cov roj thiab cov roj av uas xav tau cov kav dej loj. Piv nrog rau LSAW kav, kauv kav yuav tsum tau tsawg raw khoom rau tib txoj kab uas hla, yog li txo nqi ntau lawm. Tsis tas li ntawd, cov kav dej kauv yog welded nrog helical welds, uas tuaj yeem cuam tshuam qhov kev ntxhov siab ntau dua thaum raug quab yuam, txhim kho lub siab-kev muaj peev xwm thiab kev ruaj ntseg ntawm cov yeeb nkab.
Thib ob,kauv cevyog feem ntau welded nrog tsis siv neeg submerged arc vuam tshuab, uas muaj qhov zoo ntawm seam zoo, ceev vuam ceev thiab siab ntau lawm efficiency. Submerged arc vuam tuaj yeem ua kom muaj qhov ntom ntom thiab lub zog ntawm cov vuam seam thiab txo qhov kev pheej hmoo ntawm kev xau los ntawm vuam tsis xws. Nyob rau tib lub sijhawm, lub vuam seam ntawm kauv cov yeeb nkab tau muab faib ua ib lub voj voog, tsim ib lub kaum ntse ntse nrog lub axis ntawm cov yeeb nkab, thiab qhov kev teeb tsa no ua rau cov vuam seam zoo dua tuaj yeem tiv thaiv tawg thaum cov yeeb nkab muaj kev ntxhov siab, thiab txhim kho kev ua haujlwm ntawm cov yeeb nkab.
Tsis tas li ntawd,cev sstuaj yeem raug kuaj xyuas hauv online ultrasonic flaw thiab lwm yam kev kuaj tsis muaj kev puas tsuaj thaum lub sijhawm tsim khoom los xyuas kom meej tias qhov zoo ntawm txhua cov yeeb nkab ua tau raws li cov qauv. Cov kev tswj xyuas nruj zoo li no ua rau cov kav hlau kav muaj kev nyab xeeb dua thiab txhim khu kev qha hauv thaj chaw muaj kev pheej hmoo siab xws li roj thiab roj tsheb thauj mus los.
Thaum kawg, kauv yeeb nkab kuj muaj qhov zoo corrosion thiab hnav tsis kam. Nyob rau hauv cov txheej txheem ntawm kev thauj mus los ntawm roj thiab roj, cov yeeb nkab yuav tsum tau tiv thaiv corrosion thiab scouring nyhuv ntawm ntau yam xov xwm. Kauv cov yeeb nkab tuaj yeem txhim kho nws cov kev tiv thaiv corrosion thiab ua kom nws lub neej ntev kev pab cuam los ntawm kev kho deg xws li tshuaj tiv thaiv corrosion los yog kub-dip galvanizing thiab lwm yam kev ntsuas. Nyob rau tib lub sijhawm, cov yam ntxwv ntawm cov yeeb nkab kauv kuj ua rau nws muaj qee yam hnav tsis kam, tuaj yeem tiv taus cov khoom hauv nruab nrab ntawm cov phab ntsa sab hauv ntawm cov yeeb nkab scouring.
Nyob rau hauv cov ntsiab lus, qhov zoo ntawm kauv yeeb nkab nyob rau hauv cov roj thiab roj tsheb thauj mus los pipeline yog feem ntau xav txog nyob rau hauv nws loj txoj kab uas hla ntau lawm muaj peev xwm, siab muaj peev xwm, zoo heev vuam zoo, nruj zoo tswj ntsuas thiab zoo corrosion thiab hnav tsis kam. Cov yam ntxwv ntawm cov txheej txheem no ua rau cov kav dej kav ntev dhau los ua ib qho ntawm cov khoom tseem ceeb thiab tseem ceeb hauv kev thauj mus los ntawm cov roj thiab roj.
