Ncaj seam submerged arc welded (LSAW) pipelines, nrog rau lawv cov kev ua tau zoo tshaj, tau dhau los ua qhov kev xaiv tseem ceeb rau kev thauj mus los ntev - roj thiab roj, kev tsim hluav taws xob sab nraud, thiab kev thauj mus los ntawm cov dej. Cov txiaj ntsig tseem ceeb ntawm LSAW cov kav dej nyob hauv lawv lub zog thiab lub zog siab -cov kabmob muaj peev xwm. Cov khoom siv high-zoo qis- alloy structural steel thiab carbon steel, ua raws li cov qauv thoob ntiaj teb. Advanced ncaj seam submerged arc vuam thev naus laus zis yog ua haujlwm thaum lub sijhawm tsim khoom, ua rau cov vuam tuab tuab, sib xyaw ua ke, thiab muaj zog sib txuas. Piv nrog rau lwm hom welded pipelines, LSAW pipelines siv txuas txuas mus ntev welds, zam cov teeb meem kev ntxhov siab cuam tshuam nrog cov welds circumferential, yog li muab kev tiv thaiv zoo rau sab hauv siab los nag thiab lwm yam cuam tshuam. Lawv tuaj yeem tiv taus qhov chaw ua haujlwm hnyav xws li kev kub siab, qhov kub thiab txias, thiab cov xov xwm corrosive, txo qhov kev pheej hmoo ntawm cov kav dej xau thiab kev puas tsuaj.
LSAW pipelines ua raws li cov qauv tsim khoom nruj me ntsis txog qhov raug thiab qhov zoo ntawm qhov chaw. Los ntawm steel phaj txiav, dabtsi yog khoov, thiab sib sau rau vuam thiab tom qab-weld kho cua sov, tag nrho cov txheej txheem ntau lawm yog ua tib zoo tswj kom ntseeg tau tias qhov tseem ceeb qhov ntev xws li txoj kab uas hla, phab ntsa thickness, thiab ovality raws li tus neeg yuav tsum tau muaj. Lub raj xa dej siv cov khoom siv tshuaj tiv thaiv kev tiv thaiv- kev kho corrosion, nrog rau sab nraud 3PE / 3LPE los tiv thaiv-corrosion txheej thiab sab hauv epoxy hmoov txheej, thiab lwm yam kev xaiv. Cov tshuaj tiv thaiv no -corrosion coatings muaj cov adhesion zoo heev, abrasion tsis kam, thiab corrosion kuj, zoo cais cov kav dej los ntawm cov xov xwm corrosive xws li av, dej, thiab roj thiab roj, ua kom ntev lub raj xa dej. Txawm tias nyob rau hauv ib puag ncig hnyav xws li dej hiav txwv, suab puam, thiab permafrost, lub raj xa dej tiv thaiv{10}} kev ua haujlwm corrosion tseem nyob ruaj khov rau lub sijhawm ntev.
LSAW pipelines muaj ntau yam kev pab cuam kho kom haum raws li cov neeg siv khoom xav tau. Nyob rau hauv cov nqe lus ntawm specifications, pipeline txheej diameters li ntawm 457.2mm mus rau 1422.4mm, thiab phab ntsa thicknesses los ntawm 8mm mus rau 50mm, flexibly kho raws li kev ntsuas siab thiab daim ntawv thov scenarios. Hais txog cov khoom siv qib, qib sib txawv ntawm cov khoom siv kav dej, suav nrog cov pa roj carbon zoo tib yam, cov hlau tshwj xeeb, thiab qis- alloy steel, tuaj yeem muab tau raws li qhov yuav tsum tau ua. Tsis tas li ntawd, kev kho tshwj xeeb xws li qhov kawg beveling, xov ua, thiab flange kev sib txuas tuaj yeem ua tau raws li cov neeg siv khoom xav tau, txhim kho kev tsim kho.
LSAW pipeline cov khoom yog tsim nyob rau hauv raws li kev lag luam cov qauv, nrog nruj zoo tswj. Lub caij no, cov qauv kev ruaj ntseg siab thiab zoo heev corrosion kuj ntawm LSAW pipelines tuaj yeem txo cov nqi kho tom qab ntawm cov kav dej. LSAW pipelines txhawb nqa kev thauj mus los thiab kev teeb tsa tus qauv, thiab tuaj yeem hloov kho raws li kev tsim kho ntawm ntau lub teb chaws. Txawm hais tias nws yog segmented nteg ntawm qhov ntev - cov kav dej nyob deb lossis cov kav dej hauv qab hiav txwv docking ntawm cov chaw sab nrauv, cov txheej txheem kev sib koom ua ke tsim thiab kev teeb tsa tuaj yeem txhim kho kev tsim kho kom zoo thiab txo cov neeg ua haujlwm thiab cov nqi sijhawm ntawm - qhov chaw tsim kho.
