Tej zaum koj yuav xav tsis thoob yuav ua li cas xaiv cov yeeb nkab steel hauv koj qhov project vim tias muaj ntau hom yeeb nkab steel rau koj xaiv hauv khw. Txhawm rau xaiv qhov project ntawm ntau hom steel yeeb nkab lossis raj zoo li ib txwm muaj teeb meem mob taub hau ntawm feem ntau ntawm cov neeg siv kawg hauv lub neej.
Hauv kev lag luam steel, peb tuaj yeem pom ob yam loj ntawm cov kav hlau: welded yeeb nkab thiab seamless yeeb nkab. Feem ntau, muaj ntau tus neeg muas zaub nug peb txog yuav ua li cas xaiv ntawm ob hom yeeb nkab no. Pom tseeb, qhov sib txawv ntawm cov txheej txheem tsim khoom yog los ntawm lawv cov npe. Seamless yeeb nkab yog extruded thiab kos los ntawm ib tug billet thaum welded yeeb nkab yog tsim los ntawm ib tug sawb uas yog yob tsim thiab welded los tsim ib lub raj. Feem ntau hais lus, muaj qhov sib txawv ntawm cov yeeb nkab steel nqi ntawm ob hom steel yeeb nkab vim muaj ntau txoj kev tsim khoom hauv ib lub zeb. Ntawm qhov tod tes, txawm hais tias kev ua haujlwm siab ntawm cov yeeb nkab welded yog 20% tsawg dua li qhov zoo sib xws rau cov yeeb nkab seamless, kev ua haujlwm siab tsis yog qhov kev txiav txim siab rau xaiv cov yeeb nkab seamless tshaj welded yeeb nkab rau cov qauv ntsuas kab. Qhov txawv ntawm qhov muaj peev xwm impurities, uas txo cov corrosion kuj ntawm cov yeeb nkab tiav, yog vim li cas seamless yeeb nkab tau teev.
Tsis tas li ntawd, nrog cov txheej txheem sib txawv, yuav muaj cov khoom sib txawv. Qhov ntawd tuaj yeem ua kom pom tseeb hauv cov yeeb nkab sib txawv ntawm cov kav hlau steel. Vim cov nqi siab, kub dipped galvanized steel yeeb nkab muaj tus nqi siab dua li ntawm cov yeeb nkab electro-galvanized steel. Ntawm qhov tod tes, kub dipped galvanized steel yeeb nkab muaj ntau yam kev siv ntau dua li cov yeeb nkab electro-galvanized steel. Niaj hnub no, cov yeeb nkab electro-galvanized steel tau tawm ntawm kev lag luam steel vim yog lub teb chaws txwv tsis pub lub hom phiaj tiag tiag. Tsis tas li ntawd, los ntawm cov kws tshaj lij pom, muaj qhov sib txawv tseem ceeb ntawm ob lub kav dej los ntawm qhov pom. Ob txoj kev ua haujlwm sib txawv yuav tsis tsuas yog cuam tshuam rau daim ntawv thov tshwj xeeb hauv kev siv tswv yim, tab sis kuj yuav ua rau muaj qhov sib txawv ntawm cov yeeb nkab steel. Raws li yuav luag tag nrho cov yeeb nkab steel manufacturers paub, kub dipped galvanized steel yeeb nkab muaj ib tug tuab zinc txheej tshaj cov electro-galvanized yeeb nkab. Tsuav peb ua tib zoo saib, nws yog ib qho yooj yim los ua qhov sib txawv ntawm ob hom kav dej.
