Muab kauv cov yeeb nkab rau hluav taws cov kab
Lub ntsiab zoo ntawmMuab kauv welded yeeb nkabyog lub peev xwm los tsim cov kav hlau hlau ntawm cov kab sib txawv ntawm cov hlua khi ntawm tib qhov dav. Qhov no yog qhov tshwj xeeb tshaj plaws thaum nqaim ntawm cov hlau yuav tsum tau ua cov kab uas hla loj hlau hlau loj. Nrog rau qhov kev tsim cov khoom lag luam no, cov khoom lag luam muaj cov khoom seem tshaj plaws thiab hloov kom tau raws li cov kev xav tau ntawm cov haujlwm sib txawv thiab kev lag luam.
Tsis tas li ntawd, qhov ntev ntawm cov kauv welded kav yog heev. Feem ntau, txoj kab uas hla dhau ntau tshaj 0.12%, ua kom qhov loj me ntawm txhua cov yeeb nkab tsim tau raug thiab xwm yeem. Cov theem no ntawm qhov raug yog qhov tseem ceeb rau cov kev siv uas muaj kev ncaj ncees sab hauv yog qhov tseem ceeb.

Ntxiv rau qhov ntev ntev, muab kauv welded yeeb nkab muaj cov qauv kev cai zoo tshaj plaws. Txij li qhov deflection yog tsawg dua 1/2000, cov yeeb nkab qhia kev sib txawv me me los ntawm nws cov qauv muaj tseeb txawm tias hloov pauv tes thiab sab nraud. Qhov no ua kom ntseeg tau txhim khu kev qha thiab ua tau zoo, ua cov khoom tsim nyog rau cov ntawv thov tseem ceeb xws li cov raj hluav taws kub.
Ntxiv mus, lub ovality ntawm muab kauv welded yeeb nkab muaj tsawg dua 1%, ntxiv txhim kho nws txoj kev ua kom ruaj khov thiab kev ntseeg tau. Lub zes qe menyuam yog qhov tseem ceeb rau cov ntawv thov uas muaj cov khoom siv hluav taws xob sib zog yog qhov tseem ceeb rau cov kua dej txaus thiab kev ua tau zoo. Nrog rau kauv welded kav dej, qhov zoo thiab ua tau zoo ntawm cov kua lossis roj xa khoom tsis muaj kev cuam tshuam.
Tshwj xeeb, cov kauv welded yeeb nkab tsim cov txheej txheem tshem tawm cov kev xav tau tsoos sizing thiab ncaj cov txheej txheem. Qhov kev tshwm sim hauv lub sijhawm tseem ceeb thiab cov nqi kev txuag nyiaj, ua rau cov khoom lag luam tsis txaus siab thiab muaj txiaj ntsig. Los ntawm kev tshem tawm cov kauj ruam tsim khoom ntxiv, cov neeg lag luam txaus siab rau cov nqi ua kom muaj txiaj ntsig ntau, nce tag nrho cov phiaj xwm kev ua haujlwm.
Muab kauv welded yeeb nkab yog tshwj xeeb rauHluav Taws Hlau KabQhov uas yuav tsum muaj kev nyab xeeb thiab kev ua tau zoo yog qhov tseem ceeb. Nws cov kev zam tshwj xeeb yog qhov tseeb, kev tswj hwm kev ncaj ncees thiab kev tswj hwm rau kev thauj cov dej, ua npuas dej lossis lwm yam hluav taws kub ua kom tiv thaiv lub neej thiab vaj tse.
Tsis tas li ntawd, kauv welded yeeb nkab yog haum rau ntau cov ntawv thov, suav nrog cov roj thiab roj pipelines, cov qauv tsim qauv thiab cov phiaj xwm kev teeb tsa. Nws cov versatility thiab cov ua tau zoo dua ua rau nws cov kev xaiv txaus nyiam rau ntau qhov kev lag luam uas xav tau cov khoom lag luam steel zoo steel.
Txhawm rau suav, cov kauv welded yeeb nkab rau hluav taws yeeb nkab kab yog ib yam khoom nrog cov txiaj ntsig zoo dua thiab zoo. Nws muaj peev xwm tsim cov kav hlau hlau ntawm kev sib txawv, cov txheej txheem sib txawv, cov txheej txheem txuag tau zoo ua rau kev xaiv ntau yam thiab raug nqi. Txawm hais tias nws yog hluav taws xob piping lossis lwm yam ntaub ntawv tso cai, muab kauv welded cov yeeb nkab tuaj yeem muab cov khoom siv zoo thiab kev ntseeg tau ntawm cov haujlwm sib txawv thiab kev lag luam.
