2. Ntau hom kav hlau dub sib txawv
Raws li cov txheej txheem tsim khoom sib txawv, cov kav hlau dub feem ntau yog muab faib ua cov kav hlau welded thiab cov kav hlau seamless.
Cov Yeeb Nkab Hlau Welded:Cov yeeb nkab hlau uas vuam yog ua los ntawm kev vuam cov hlau phaj lossis cov strips uas dov rau hauv ib lub raj. Nws tseem hu ua ERW (Electric Resistance Welded) yeeb nkab. Hom yeeb nkab no feem ntau muaj lub zog zoo thiab tawv. Cov txheej txheem tsim cov yeeb nkab hlau uas vuam yog qhov yooj yim, thiab nws tuaj yeem tsim cov yeeb nkab ntev dua ntawm tus nqi qis dua.
Cov Yeeb Nkab Hlau Tsis Muaj Qhov Txuas:Cov yeeb nkab hlau tsis muaj qhov sib txuas yog tsim los ntawm kev dov kub lossis txias yam tsis muaj cov seams welded. Hom yeeb nkab no muaj zog dua thiab muaj kev nyab xeeb dua nyob rau hauv kev kub siab thiab cov xwm txheej hnyav vim nws tsis muaj qhov tsis muaj zog (xws li welds).
3. Cov yeeb nkab dub yog siv rau dab tsi?
Cov yeeb nkab dub siv dav hauv ntau yam kev siv, suav nrog kev siv kav dej, kev faib roj, thiab kev txhawb nqa cov qauv.
Cov yeeb nkab hlau tsis muaj qhov txuasyog tsim tsis muaj cov seams lossis welds, uas ua rau nws lub zog ntxiv thiab ua rau nws yog ib qho kev xaiv zoo dua rau kev thauj cov roj thiab cov kua dej hauv qab qhov siab siab. Hom yeeb nkab no yog qhov tseem ceeb hauv cov ntawv thov uas qhov kev ua tiav ntawm cov qauv tseem ceeb, xws li hauv cov kav dej roj thiab roj av.
Nyob rau sab tes tod,dub welded hlau yeeb nkabfeem ntau siv rau ntau yam kev siv, suav nrog cov kav dej, kev xa roj thiab cov tshuab txau dej tua hluav taws. Nws cov yam ntxwv tiv taus hluav taws ua rau nws tsim nyog rau cov tshuab zoo li no, qhov twg kev ntseeg siab thiab kev nyab xeeb yog qhov tseem ceeb.
