    Thaum xav txog cov lus qhia tshwj xeeb rau cov kav hlau txuas txuas, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus tseem ceeb xws li txoj kab uas hla, phab ntsa thickness thiab cov khoom qib.Txoj kab uas hla ntawm cov yeeb nkab txiav txim siab nws lub peev xwm los thauj cov kua los yog roj, thaum lub phab ntsa tuab ua lub luag haujlwm tseem ceeb hauv nws cov qauv kev ntseeg siab thiab kev ua haujlwm siab.Tsis tas li ntawd, cov khoom siv qib sawv cev rau qhov zoo thiab muaj pes tsawg leeg ntawm cov hlau siv thiab yog qhov tseem ceeb hauv kev ua kom lub neej ntev thiab kev ua haujlwm ntawm cov yeeb nkab hauv ib daim ntawv thov.

    Hauv kev tsim kho ntawmcov kav dej loj, kauv seam kav muaj ntau yam zoo.Lawv lub zog tensile siab thiab corrosion kuj ua rau lawv zoo tagnrho rau kev thauj cov dej hla kev deb, thaum lawv yooj yim tso cai rau yooj yim installation nyob ib ncig ntawm obstacles thiab nyob rau hauv cov struts struts.Tsis tas li ntawd, kev siv cov kav hlau txuas hauv cov kav dej hauv cov kav dej ua kom muaj kev nyab xeeb thiab muaj txiaj ntsig kev thauj mus los ntawm cov pa roj, muab cov peev txheej tseem ceeb rau thaj chaw, kev lag luam thiab kev lag luam.

    kauv steel yeeb nkab

    Nyob rau sab hauv tsev, kauv seam yeeb nkab specifications yog tswj hwm los ntawm kev lag luam cov qauv thiab cov kev cai los xyuas kom meej lawv zoo thiab kev ua tau zoo.Piv txwv li, lub koom haum American Petroleum (API) tau tsim cov qauv rau kev tsim thiab siv cov kauv-seam yeeb nkab uas qhia txog qhov yuav tsum tau muaj rau qhov loj, lub zog, thiab cov txheej txheem kuaj.Tsis tas li ntawd, American Society for Testing and Materials (ASTM) muab cov khoom muaj pes tsawg leeg thiab cov cuab yeej cuab tam tshwj xeeb rau cov kav hlau txuas txuas ntxiv kom ntseeg tau tias lawv muaj kev ntseeg siab thiab ua raws li cov qauv kev lag luam.

    Nyob rau hauv cov ntsiab lus, cov kauv welded yeeb nkab specification yog ib qho tseem ceeb rau lawv lub luag hauj lwm nyob rau hauv kev tsim kho vaj tse.Seb siv rau cov dej mains los yoggas kab, cov kav dej no muaj lub zog tsis sib xws, durability thiab versatility, ua rau lawv indispensable nyob rau hauv niaj hnub ntiaj teb no.Los ntawm kev ua raws li cov qauv kev lag luam thiab cov kev cai, kev siv cov kav hlau txuas txuas ua kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm cov txheej txheem tseem ceeb, ua rau txoj kev txhim kho kom ruaj khov thiab kev vam meej hauv zej zog.
