    Qhov zoo ntawm kauv welded kav hauv cov kav dej loj:

    1. Muaj zog thiab kav ntev:

    Cov kauv vuam tshuab siv nyob rau hauv cov kav dej no tsim ib qho kev nruam, seamless qauv nrog superior zog thiab tsis kam mus rau siab sab hauv thiab sab nraud.Tsis tas li ntawd, nruj fitting kauv seams txhim khu kev ncaj ncees tag nrho ntawm cov yeeb nkab, txo qhov kev pheej hmoo ntawm kev xau los yog tawg.Qhov kev ua haujlwm ntev no ua kom lub neej ua haujlwm ntev rau koj cov dej hauv dej, txo kev tu thiab hloov cov nqi.

    2. Corrosion kuj:

    Cov kab dej tseem ceeb raug cuam tshuam rau ntau yam ntawm ib puag ncig, nrog rau cov dej noo, tshuaj thiab av.Kauv welded kav feem ntau yog tsim los siv cov khoom siv corrosion-resistant xws li stainless hlau, kom ntseeg tau zoo heev tiv thaiv xeb, yaig, thiab lwm yam corrosion.Qhov kev tiv thaiv no txuas ntxiv lub neej ntawm cov kav dej, tiv thaiv kev degradation thiab tswj dej zoo.

    3. Tus nqi-zoo:

    Kev nqis peev hauv kauv welded kav raucov kav dej lojstuaj yeem ua pov thawj los ua qhov kev xaiv them nqi hauv lub sijhawm ntev.Nws cov qauv ruaj khov thiab kev tiv thaiv corrosion txo qhov zaus ntawm kev kho thiab hloov, yog li txuag cov nqi kho tseem ceeb.Tsis tas li ntawd, lawv yooj yim rau nruab, lub teeb yuag, thiab txo qhov xav tau kev txhawb nqa ntxiv, ua rau lawv yooj yim thiab siv tau zoo rau cov kav dej loj.

    4. Flexibility thiab Versatility:

    Kauv welded yeeb nkab muaj qib siab ntawm kev hloov pauv thiab ntau yam hauv nws cov ntawv thov.Lawv tuaj yeem tsim nyob rau hauv ntau txoj kab uas hla, qhov ntev thiab thicknesses, tso cai rau lawv los kho kom haum raws li qhov project tshwj xeeb.Qhov kev hloov pauv no tso cai rau lawv hloov mus rau qhov sib txawv thiab cov av sib txawv, ua rau lawv muaj kev xaiv zoo tshaj plaws rau cov kav dej loj hauv nroog thiab nyob deb nroog.

    5. Environmental sustainability:

    Ntxiv nrog rau lawv cov txiaj ntsig zoo, cov kav dej welded kauv kuj ua rau muaj txiaj ntsig zoo rau ib puag ncig kev ruaj ntseg.Cov ntaub ntawv siv nyob rau hauv nws cov kev tsim kho yog recyclable, txo tag nrho cov pa roj carbon hneev taw.Tsis tas li ntawd, nws txoj kev tsim seamless minimizes dej poob vim qhov xau, yog li tiv thaiv cov peev txheej tseem ceeb no.

    ib.Txoj kev deoxidation yog tsim raws li hauv qab no:

    FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al).

    b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb.

    Hauv kev xaus:

    Ua kom ntseeg tau qhov ua tau zoo thiab kav ntev ntawm koj cov kav dej tseem ceeb yog qhov tseem ceeb los xyuas kom muaj kev ntseeg tau dej.Kev siv cov kauv welded yeeb nkab hauv cov nocev kabmuaj ntau yam zoo, nrog rau muaj zog, corrosion kuj, nqi-zoo, yooj thiab ib puag ncig sustainability.Raws li peb ua hauj lwm los tsim kom muaj kev ruaj ntseg thiab zoo dej infrastructure, kev nqis peev nyob rau hauv advanced technologies xws li kauv welded yeeb nkab yog qhov tseem ceeb.
