Txheej txheem cej luam
Nrog peb cov thev naus laus zis thiab peb tus ntsuj plig ntawm kev tsim kho tshiab, kev sib koom tes, cov txiaj ntsig thiab kev loj hlob, peb yuav tsim kom muaj kev vam meej yav tom ntej ua ke nrog koj qhov kev ntseeg siab ruaj khov steel yeeb nkab, Peb tuav cov sij hawm xa tuaj raws sij hawm, tsim qauv tshiab, zoo tshaj plaws thiab pob tshab rau peb. cov neeg yuav khoom. Peb lub moto yuav tsum muab cov khoom zoo hauv lub sijhawm teev tseg.
Txais tos tuaj xyuas peb lub tuam txhab, lub Hoobkas thiab peb lub tsev rau khoom uas qhia peb cov Tshuag uas yuav ua tau raws li koj qhov kev cia siab. Lub caij no, nws yooj yim mus xyuas peb lub vev xaib, thiab peb cov neeg ua haujlwm muag yuav sim lawv qhov zoo tshaj plaws los muab cov kev pabcuam zoo tshaj plaws rau koj. Nco ntsoov tiv tauj peb yog tias koj xav tau cov ntaub ntawv ntxiv. Peb lub hom phiaj yog los pab cov neeg siv khoom paub lawv lub hom phiaj. Peb tab tom ua haujlwm zoo los ua kom tiav qhov xwm txheej yeej-yeej.
Hais txog carbon steel welded yeeb nkab, muaj ib tug zoo poeple hu ua MS yeeb nkab, uas txhais tau hais tias cov kav dej ua los ntawm cov hlau me me / qis carbon steel (carbon steel uas carbon cov ntsiab lus qis dua 0.25%). Cov yeeb nkab zoo no feem ntau yog siv rau hauv kev tsim qauv, scaffold thiab lwm yam. Cov yeeb nkab zoo no yog qhov muag muag, tsis tuaj yeem tiv taus ntau lub zog thiab siab, yog li kuj tuaj yeem siv rau hauv kev thauj cov kua siab tsawg. Vim tias cov hlau zoo li no muaj cov cuab yeej siv tshuab tsawg, yuav tsis siv rau hauvkev siv scenario uas muaj qhov yuav tsum tau muaj siab, yog li thaum tib neeg hais txog MS yeeb nkab, ib txwm txhais tau tias welded yeeb nkab.
Daim ntawv thov
Nws yog siv rau kev quab yuam thiab qhov siab, thiab rau lub hom phiaj dav dav, dej, roj thiab cov kav dej.
