Cov kav hlau hlau tuaj yeem raug cais raws li cov txheej txheem dov, seb puas muaj cov seams los yog tsis, thiab cov duab ntawm seem. Raws li kev faib tawm ntawm cov txheej txheem dov, cov yeeb nkab steel tuaj yeem muab faib ua cov kav dej kub-dov hlau thiab cov kav dej txias-dov hlau; Raws li seb cov kav hlau puas muaj seams, cov kav hlau tau muab faib ua cov kav hlau tsis sib haum thiab cov kav hlau welded, cov uas feem ntau siv welded steel kav tuaj yeem muab faib ua cov kav dej ntau zaus raws li hom vuam. , ncaj seam submerged arc welded yeeb nkab, kauv submerged arc welded yeeb nkab, thiab lwm yam.
Phab ntsa thickness ntawm seamless steel yeeb nkab yog tuab thiab txoj kab uas hla thickness yog me me. Txawm li cas los xij, txoj kab uas hla ntawm cov yeeb nkab yog txwv, nws daim ntawv thov kuj raug txwv, thiab cov nqi tsim khoom, tshwj xeeb tshaj yog cov nqi tsim khoom ntawm cov kav dej loj seamless steel, kuj yog siab heev.
Lub high-frequency welded yeeb nkab muaj zoo raj zoo thiab niaj hnub phab ntsa thickness. Cov burrs sab hauv thiab sab nrauv tsim los ntawm vuam yog smoothed los ntawm cov cuab yeej siv, thiab qhov zoo ntawm cov vuam seam yog nruj me ntsis tswj los ntawm kev sim online tsis muaj kev puas tsuaj. Lub degree ntawm automation yog siab thiab tus nqi ntau lawm yog tsawg. Txawm li cas los xij, cov phab ntsa tuab yog nyias nyias thiab cov yeeb nkab txoj kab uas hla yog me me, uas yog tshwj xeeb tshaj yog haum rau ua cov yeeb nkab truss qauv hauv steel qauv.
Qhov ncaj seam submerged arc welded yeeb nkab txais cov txheej txheem ob-sided submerged arc vuam txheej txheem, uas yog welded nyob rau hauv zoo li qub, qhov vuam zoo yog siab, qhov vuam yog luv, thiab qhov tshwm sim ntawm qhov tsis xws luag yog me me. Cov yeeb nkab steel tau nthuav dav los ntawm tag nrho qhov ntev, cov yeeb nkab zoo zoo, qhov loj yog qhov tseeb, cov yeeb nkab phab ntsa thickness ntau thiab cov yeeb nkab txoj kab uas hla yog dav, qhov degree ntawm automation yog siab, thiab cov nqi ntau lawm yog qis dua piv nrog seamless steel yeeb nkab, haum rau cov tsev, txuas hniav, dams, thiab offshore platforms sib npaug steel qauv bearing kab, super-span lub tsev cov qauv thiab cov ncej hlau tiv thaiv.
Lub vuam seam ntawm kauv submerged arc welded yeeb nkab yog muab kauv faib, thiab vuam seam ntev. Tshwj xeeb tshaj yog thaum welding nyob rau hauv dynamic tej yam kev mob, lub vuam seam tawm ntawm txoj kev taw tes ua ntej txias, thiab nws yog heev yooj yim los tsim vuam kub tawg. Yog li ntawd, nws cov dabtsi yog khoov, tensile, compressive thiab torsional zog yog nyob deb inferior rau cov LSAW kav, thiab nyob rau tib lub sij hawm, vim muaj kev txwv ntawm vuam txoj hauj lwm, lub eeb-puab thiab ntses-ridge-shaped welds ua rau cov tsos. Tsis tas li ntawd, thaum lub sij hawm kev tsim kho, txoj kab sib tshuam weld ntawm lub pob ntawm cov kauv welded niam txiv yeeb nkab phua lub kauv seam, uas ua rau muaj kev ntxhov siab loj vuam, yog li ua rau muaj kev ruaj ntseg zoo ntawm cov khoom siv. Yog li ntawd, qhov kev ntsuam xyuas tsis muaj kev puas tsuaj ntawm cov kauv welded yeeb nkab vuam yuav tsum tau ntxiv dag zog. Xyuas kom cov vuam zoo, txwv tsis pub cov kauv submerged arc welded yeeb nkab yuav tsum tsis txhob siv nyob rau hauv lub sij hawm tseem ceeb steel qauv.
