Nkag siab txog cov txheej txheem thiab cov qauv ntawm cov kauv welded steel kav raws li EN10219

Muab kauv welded yeeb nkabPuas yog ib qho tseem ceeb ntawm ntau yam kev lag luam suav nrog cov roj thiab roj av, tsim kho thiab cov dej vaj tse. Cov kav dej yog tsim siv cov txheej txheem tshwj xeeb hu ua muab kauv vuam, uas muaj feem cuam tshuam nrog cov hlau los tsim cov qauv txuas ntxiv. Txoj kev tsim khoom no muaj ntau yam zoo, suav nrog lub zog siab, ua rau lub zog thiab cov txiaj ntsig zoo. Tsis tas li ntawd xwb, muab kauv welded kav ua tiav nrog cov qauv thoob ntiaj teb xws li EN10219 kom ntseeg tau tias lawv qhov ua tau zoo thiab ua tau zoo.

E10219yog cov txheej txheem European uas qhia txog cov txheej txheem kev ua haujlwm rau cov kab kev ua kom zoo welded cov kab ntawm cov hlau tsis-alloy thiab nplua-nplej. Cov qauv qhia cov qauv no rau cov txheej txheem tsim khoom, cov khoom siv thiab seem thiab qhov tsis txaus ntseeg ntawm kev sib tw steel kav hlau kom paub meej tias lawv cov ntawv thov kev tsim qauv.

Zus tau tsim cov muab kauv weld txiav cov kav hlau welded thawj xaiv cov coils zoo, thiab tom qab ntawd uncoils thiab pub rau hauv cov kauv vuam tshuab. Lub tshuab siv cov txheej txheem vuam txuas ntxiv mus koom nrog cov npoo ntawm cov hlau sawb, tsim kom muaj kauv sab nrauv raws qhov ntev ntawm cov yeeb nkab. Cov cuab yeej hauv Welds tau txais kev kuaj tsis yog kev ua kom peb txoj kev ncaj ncees thiab lub zog. Tom qab vuam, cov kav dej dhau ntau cov txheej txheem ua tiav, suav nrog sizing, ncaj thiab tshuaj xyuas, kom tau raws li qhov yuav tsum tau ua ntawm EN10219.

Ib qho ntawm qhov zoo ntawm cov kauv welded steel yeeb nkab yog nws muaj peev xwm tiv thaiv lub siab sab hauv thiab sab nraud thauj khoom thiab roj av hauv ntau yam kev lag luam. Ib qho ntxiv, cov kauv vuam cov txheej txheem tuaj yeem tsim cov kav dej tsim cov dej hauv ntau qhov diameters thiab tuab, muab cov qauv siv thiab kev tsim kho. Cov kav dej no tseem tiv taus corrosion, uas ntxiv txhim kho lawv lub sijhawm ntev thiab ua tau zoo hauv kev xav tau ib puag ncig.

Ua raws li EN10219 yog qhov tseem ceeb kom ntseeg tau tias yog qhov zoo thiab kev ntseeg tau ntawm muab kauv welded steel kav hlau. Tus qauv uas cuam tshuam cov khoom siv rau cov khoom siv, cov khoom siv neeg siv tshuab thiab seem tsis tu ncua kom ntseeg tau tias cov kav dej tau ua tiav cov qauv kev ua tau zoo.

Ib qho ntxiv, EN10219 tseem qhia cov txheej txheem kuaj thiab cov txheej txheem pov thawj uas cov kws ua lag luam yuav tsum ua raws li, suav nrog kev kuaj cov neeg siv tshuab thiab kev tshuaj xyuas tshuab. Los ntawm adhering rau cov qauv nruj no, cov chaw tsim khoom tuaj yeem muab cov neeg siv khoom zoo thiab ua tau zoo ntawm cov kauv yeeb nkab welded steel.

Hauv cov ntsiab lus, kev tsim khoom thiab cov qauv rau cov kauv welded steel kav tau hais txog kev ntseeg tau thiab ua haujlwm ntawm cov khoom tseem ceeb no. Los ntawm kev siv kauv vuam cov txheej txheem thiab cov qauv tsim kho kom nruj nruj qauv, cov chaw tsim khoom tuaj yeem tsim cov yeeb nkab zoo uas tau ua rau cov kev lag luam zoo ntawm ntau yam kev lag luam. Raws li qhov tshwm sim, EN10219 dhau los ua ib lub moj khaum tseem ceeb rau kev tsim khoom, kev sim thiab kev siv ntawv pov thawj ntawm cov kauv vauv loj dua qub thiab cov phiaj xwm kev tsim kho thoob ntiaj teb.
