Cov yeeb nkab hlau tuaj yeem muab faib ua pawg raws li cov txheej txheem dov, seb puas muaj cov seams lossis tsis muaj, thiab cov duab ntawm seem. Raws li kev faib tawm ntawm cov txheej txheem dov, cov yeeb nkab hlau tuaj yeem muab faib ua cov yeeb nkab hlau kub dov thiab cov yeeb nkab hlau txias dov; raws li seb cov yeeb nkab hlau puas muaj seams, cov yeeb nkab hlau raug muab faib ua cov yeeb nkab hlau tsis muaj seamless thiab cov yeeb nkab hlau welded, ntawm cov yeeb nkab hlau welded feem ntau siv tuaj yeem muab faib ua cov yeeb nkab welded zaus siab raws li hom vuam., ncaj seam submerged arc welded yeeb nkab, kauv submerged arc welded yeeb nkab, thiab lwm yam.
Lub phab ntsa tuab ntawm cov yeeb nkab hlau seamless yog qhov tuab thiab lub thickness ntawm txoj kab uas hla yog qhov me me. Txawm li cas los xij, lub yeeb nkab txoj kab uas hla yog txwv, nws daim ntawv thov kuj txwv, thiab tus nqi tsim khoom, tshwj xeeb tshaj yog tus nqi tsim khoom ntawm cov yeeb nkab hlau seamless loj, yog qhov siab.
Cov yeeb nkab vuam uas muaj zaus siab muaj cov duab zoo thiab cov phab ntsa tuab sib npaug. Cov burrs sab hauv thiab sab nraud uas tsim los ntawm kev vuam raug ua kom du los ntawm cov cuab yeej sib xws, thiab qhov zoo ntawm cov xov vuam raug tswj hwm nruj me ntsis los ntawm kev sim tsis puas tsuaj hauv online. Qib ntawm kev ua haujlwm tsis siv neeg siab thiab tus nqi tsim khoom qis. Txawm li cas los xij, cov phab ntsa tuab yog nyias thiab lub yeeb nkab txoj kab uas hla me me, uas yog qhov tshwj xeeb tshaj yog rau kev ua cov qauv yeeb nkab truss hauv cov qauv hlau.
Cov yeeb nkab ncaj ncaj uas tau muab tso rau hauv qab arc welded siv cov txheej txheem vuam ob sab uas tau muab tso rau hauv qab arc welding, uas tau muab tso rau hauv qab cov xwm txheej zoo li qub, qhov zoo ntawm kev vuam yog siab, qhov vuam luv luv, thiab qhov tshwm sim ntawm qhov tsis zoo yog me me. Cov yeeb nkab hlau tau nthuav dav thoob plaws hauv qhov ntev, cov duab yeeb nkab zoo, qhov loj me yog qhov tseeb, cov yeeb nkab hlau phab ntsa tuab thiab cov yeeb nkab txoj kab uas hla dav, qib ntawm kev ua haujlwm tsis siv neeg yog siab, thiab tus nqi tsim khoom qis dua piv rau cov yeeb nkab hlau tsis muaj seamless, tsim rau cov tsev, choj, pas dej, thiab cov chaw ua haujlwm hauv hiav txwv. Cov qauv hlau sib npaug uas muaj cov kem, cov qauv tsev super-span thiab cov qauv mast uas xav tau kev tiv thaiv cua thiab av qeeg.
Lub vuam seam ntawm cov yeeb nkab uas muaj kauv submerged arc welded yog spirally faib, thiab lub vuam seam ntev. Tshwj xeeb tshaj yog thaum vuam nyob rau hauv cov xwm txheej dynamic, lub vuam seam tawm ntawm qhov chaw ua ntej txias, thiab nws yooj yim heev rau kev tsim cov kab nrib pleb kub vuam. Yog li ntawd, nws cov khoom khoov, tensile, compressive thiab torsional tsis zoo li cov yeeb nkab LSAW, thiab tib lub sijhawm, vim muaj kev txwv ntawm txoj haujlwm vuam, cov saddle-puab thiab ntses-ridge-puab welds tsim cuam tshuam rau qhov tsos. Tsis tas li ntawd, thaum lub sijhawm tsim kho, cov kab sib tshuam ntawm qhov node ntawm cov yeeb nkab niam txiv spiral welded faib cov spiral seam, ua rau muaj kev ntxhov siab vuam loj, yog li ua rau kev ua haujlwm kev nyab xeeb ntawm cov khoom tsis muaj zog. Yog li ntawd, kev sim tsis puas tsuaj ntawm cov yeeb nkab spiral welded yuav tsum tau ua kom muaj zog. Xyuas kom meej qhov zoo ntawm kev vuam, txwv tsis pub lub yeeb nkab spiral submerged arc welded yuav tsum tsis txhob siv rau hauv cov sijhawm tseem ceeb ntawm cov qauv hlau.
