Thaum nws los txog raukev tsim cov kav dejCov khoom siv no yog qhov tseem ceeb heev rau kev ua kom lawv cov khoom ruaj khov thiab tiv taus corrosion.Cov kav hlau LSAW carbon, tseem hu ua Longitudinal Submerged ArcCov kav dej vuam, yog ib qho kev xaiv nrov vim lawv lub zog siab thiab kev ntseeg siab. Txhawm rau txhim kho lawv txoj kev tiv thaiv xeb, cov kav dej no tuaj yeem coated nrog peb txheej qauv polyethylene tiv thaiv xeb hu ua 3PE. Hauv blog no, peb yuav tshawb nrhiav cov txiaj ntsig ntawm kev sivCov kav hlau carbon LSAW coated 3PEthiab vim li cas lawv thiaj yog qhov kev xaiv zoo heev rau ntau yam lag luam.
Cov txheej txheem tiv thaiv xeb 3PE yog ib qho kev daws teeb meem zoo uas tiv thaiv cov kav hlau LSAW carbon los ntawm kev xeb thiab ua kom lawv lub neej ntev dua. Cov qauv 3PE muaj peb txheej, pib nrog txheej hmoov epoxy uas muab kev nplaum zoo heev thiab kev sib txuas rau ntawm qhov chaw ntawm cov kav dej. Qhov no ua raws li txheej nplaum, uas ua kom muaj zog ntxiv rau kev sib txuas ntawm epoxy thiab txheej kawg - polyethylene tiv thaiv xeb. Cov txheej polyethylene ua haujlwm ua ib qho thaiv, tiv thaiv dej, tshuaj lom neeg, thiab lwm yam tshuaj corrosive kom tsis txhob mus txog sab hauv ntawm cov kav dej. Ntxiv mus, nws tuaj yeem tiv taus qhov kub txog li 80 ° C, ua rau nws haum rau ntau yam kev siv.
Piv rau 2PE txheej, qhov ntxiv ntawm cov hmoov epoxy txheej hauv 3PE coated LSAW carbon steel kav dej ua rau muaj kev ua haujlwm zoo ntawm cov khoom tiv thaiv xeb. Cov txheej ntxiv no ua rau muaj kev ruaj khov thiab tiv taus kev hnav thiab tsim kua muag, ua kom cov kav dej tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav. Cov xim feem ntau ntawmCov kav dej 3PE coatedyog xim dub, thiab lawv ua raws li cov qauv thoob ntiaj teb xws li DIN30670, CAN/CSA Z245.21, thiab ISO21809. Cov qauv nruj no ua kom ntseeg tau tias cov kav dej ua tau raws li qhov yuav tsum tau ua thiab cov qauv kev ua tau zoo, ua rau lawv yog qhov kev xaiv txhim khu kev qha rau ntau yam lag luam.
Ntawm Botop Steel, peb tshwj xeeb hauv kev muab cov kav hlau LSAW carbon zoo nrog 3PE txheej tiv thaiv xeb. Peb cov kav dej muaj ntau qhov ntau thiab tsawg, qib, thiab cov lus qhia kom tau raws li cov kev xav tau tshwj xeeb ntawm peb cov neeg siv khoom. Nrog peb txoj kev cog lus rau kev ua tau zoo thiab kev saib xyuas kom meej, peb xyuas kom meej tias peb cov kav dej ua tau raws li cov qauv kev lag luam siab tshaj plaws. Tsis tas li ntawd, peb cov kav dej tau coated nrog FBE tiv thaiv xeb los ntawm sab hauv, ntxiv txhim kho lawv txoj kev tiv thaiv xeb. Lub txheej FBE sab hauv tsis muaj tshuaj lom thiab pab tiv thaiv xeb thaum txhim kho qhov ntws ntawm roj thiab kua hauv.cov kav dejQhov no ua rau peb cov kav dej hlau LSAW uas muaj 3PE coated yog qhov kev xaiv zoo rau kev lag luam xws li roj thiab roj av, kev muab dej, thiab kev tsim kho.
Xaus lus,Cov kav hlau carbon LSAW coated 3PEmuaj ntau yam txiaj ntsig, suav nrog cov khoom tiv thaiv xeb zoo tshaj plaws, ua haujlwm tau ntev, thiab tiv taus kev hnav thiab tsim kua muag. Kev sib xyaw ua ke ntawm cov hmoov epoxy, txheej nplaum, thiab txheej polyethylene tiv thaiv xeb ua kom cov kav dej tuaj yeem tiv taus cov xwm txheej hnyav, ua rau lawv haum rau ntau yam kev siv. Ntawm Botop Steel, peb muaj kev txaus siab rau kev muabcov kav dej zoouas ua tau raws li cov qauv thoob ntiaj teb thiab ua tau ntau tshaj qhov cov neeg siv khoom xav tau. Nqis peev rau hauv cov kav dej hlau LSAW uas muaj 3PE txheej rau kev daws teeb meem kav dej uas ntseeg tau thiab siv tau ntev.
