Kauv welded kav (SSAW) rau cov dej txuag dej yog feem ntau muab kauv welded steel kav nrog cov diameters loj, vim tias cov dej dhau los ntawm ib lub sij hawm loj, uas tuaj yeem txhim kho kev ua haujlwm zoo.Txij li cov phab ntsa sab hauv ntawm cov kauv steel yeeb nkab yog niaj hnub ntxuav los ntawm dej, cov phab ntsa sab hauv feem ntau tsis kho nrog kev tiv thaiv corrosion, tab sis sab nrauv feem ntau yog nyob rau hauv daim ntawv ntawm nyiaj siv ua haujlwm, yog li kev tiv thaiv corrosion yuav tsum tau ua los tiv thaiv. los nag yaig thiab tshav ntuj, yog li qhov yuav tsum tau rau cov txheej txheem tiv thaiv corrosion yog siab dua.

Ua ntej anticorrosion ntawm kauv steel kav rau cov dej txuag dej, qhov saum npoo ntawm cov kav hlau yuav tsum tau sandblasted, thiab qib yuav tsum ncav cuag st2.5.Tom qab sandblasting, thov cov tshuaj tiv thaiv corrosion primer tam sim ntawd.Cov tshuaj tiv thaiv corrosion feem ntau yog epoxy zinc-nplua nuj xim nrog zinc cov ntsiab lus ntawm 70% lossis ntau dua, nruab nrab yog epoxy mica xim, thiab txheej txheej sab nraud yog tiv thaiv oxidation thiab corrosion.Polyurethane xim.

Ua ntej tawm hauv lub Hoobkas, cov kav hlau kav yuav tsum tau kuaj xyuas cov khoom siv kho tshuab, flattening thiab flaring, thiab yuav tsum ua kom tau raws li cov qauv kev cai.Kauv welded steel kav muaj qhov yooj yim dua nyob rau hauv ntau txoj kab uas hla thiab phab ntsa thickness specifications, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov high-qib tuab-walled kav, tshwj xeeb tshaj yog me me thiab nruab nrab-inch tuab-walled kav.Muaj ntau qhov yuav tsum tau ua nyob rau hauv cov nqe lus ntawm kauv steel yeeb nkab specifications.Txoj kab uas hla thiab qhov luaj li cas ntawm cov kauv steel yeeb nkab yuav tsum tau tswj tau yooj yim.

Kev siv los tiv thaiv corrosion engineering yuav tsum ua raws li cov hauv qab no ua ntej nws tuaj yeem siv tau:

Ua ntej, cov phiaj xwm thiab lwm cov ntaub ntawv kev ua tiav tiav, thiab cov duab kos yuav tsum tau sib koom ua ke los tshuaj xyuas.Thib ob, kev tshaj tawm kev tshaj tawm ntawm txoj kev npaj tsim kho tiav, thiab kev qhia txog kev nyab xeeb thiab kev cob qhia tsim nyog tau ua tiav.Thib peb, tag nrho cov khoom siv, cov yeeb nkab fittings thiab fittings yuav tsum muaj daim ntawv pov thawj Hoobkas, lossis daim ntawv pov thawj ntawm tus account.Plaub, cov ntaub ntawv, machinery, khoom siv thiab chaw ua haujlwm tau zoo.Qhov thib tsib, yuav tsum muaj cov cuab yeej tiv thaiv kev ruaj ntseg thiab txhim khu kev qha, thiab kev tsim kho dej, hluav taws xob, thiab roj yuav tsum muaj peev xwm ua tau raws li kev tsim kho txuas ntxiv.
