Longitudinal Submerge-arc Welded pipes luv luv rau LSAW yeeb nkab yog ib hom steel yeeb nkab uas nws vuam seam yog longitudinally parallel rau steel yeeb nkab, thiab cov ntaub ntawv raw yog steel phaj, yog li cov phab ntsa thickness ntawm LSAW kav yuav hnyav dua piv txwv li 50 hli. , thaum sab nraud txoj kab uas hla txwv rau 1420mm utmost.LSAW yeeb nkab muaj qhov zoo ntawm cov txheej txheem tsim khoom yooj yim, kev ua haujlwm siab ntau lawm, tus nqi qis.
Ob chav Submerged Arc Welded (DSAW) yeeb nkab yog ib hom kauv vuam seam steel yeeb nkab ua los ntawm steel kauj raws li raw khoom, feem ntau sov extrusion thiab welded los ntawm tsis siv neeg ob-sided submerged arc vuam txheej txheem.Yog li ib qhov ntev ntawm DSAW yeeb nkab tuaj yeem yog 40meters thaum tib qhov ntev ntawm LSAW yeeb nkab tsuas yog 12 meters.Tab sis qhov siab tshaj plaws phab ntsa thickness ntawm DSAW kav yuav yog 25.4 hli nkaus xwb vim muaj kev txwv ntawm cov kub dov coils.
Ib qho tseem ceeb ntawm kauv steel yeeb nkab yog qhov sab nraud tuaj yeem ua tau loj heev, Cangzhou Spiral Steel Pipes Group Co.ltd tuaj yeem tsim cov kav dej loj nrog sab nraud 3500mm utmost.Thaum lub sij hawm tsim cov txheej txheem, cov hlau kauj yog deformed tusyees, cov residual kev nyuaj siab yog me me, thiab nto tsis khawb.Cov txheej txheem kauv steel yeeb nkab muaj qhov yooj yim dua nyob rau hauv qhov loj ntawm txoj kab uas hla thiab phab ntsa thickness, tshwj xeeb tshaj yog nyob rau hauv cov qib high-qib, loj phab ntsa thickness yeeb nkab, thiab me me txoj kab uas hla nrog loj phab ntsa thickness yeeb nkab, uas muaj incomparable zoo dua lwm yam txheej txheem.Nws tuaj yeem ua tau raws li cov kev xav tau ntau ntawm cov neeg siv hauv cov khoom siv kauv steel yeeb nkab specifications.Cov txheej txheem ob-sided submerged arc vuam txheej txheem tuaj yeem paub vuam ntawm txoj haujlwm zoo tshaj plaws, uas tsis yooj yim kom muaj qhov tsis xws luag xws li misalignment, vuam sib txawv thiab tsis tiav qhov nkag, thiab nws yooj yim los tswj cov vuam zoo.Txawm li cas los xij, piv nrog cov yeeb nkab ncaj seam nrog tib qhov ntev, qhov ntev vuam nce 30 ~ 100%, thiab cov khoom ceev yog tsawg.
