Cov yeeb nkab steel tuaj nyob rau hauv ntau hom thiab ntau thiab tsawg.Seamless yeeb nkab yog ib qho kev xaiv tsis-welded, ua los ntawm hollowed steel billet.Thaum nws los txog rau welded steel kav, muaj peb txoj kev xaiv: ERW, LSAW thiab SSAW.
ERW kav dej yog ua los ntawm kev tiv thaiv welded steel daim hlau.LSAW yeeb nkab yog ua los ntawm longitudinal submerged arc welded steel phaj.SSAW yeeb nkab yog ua los ntawm kauv submerged arc welded steel phaj.
Cia peb ua tib zoo saib txhua hom yeeb nkab, sib piv lawv qhov sib txawv, thiab siv cov lus piav qhia kom raug li cas.
Seamless steel raj
Seamless raj yog ua los ntawm stainless hlau billet, uas yog rhuab thiab perforated los ua ib ncig hollow seem.Vim tias cov yeeb nkab tsis muaj seamless tsis muaj qhov chaw vuam, nws suav hais tias yog qhov muaj zog dua cov yeeb nkab welded thiab tsis tshua muaj corrosion, yaig thiab tsis ua haujlwm.
Txawm li cas los xij, tus nqi ib tuj ntawm seamless yeeb nkab yog 25-40% siab dua li ntawm ERW yeeb nkab.Seamless steel yeeb nkab qhov ntau thiab tsawg ntawm 1/8 nti mus rau 36 nti.
Resistance vuam (ERW) yeeb nkab
ERW (tsis kam vuam) steel yeeb nkab yog tsim los ntawm dov hlau rau hauv cov yeeb nkab thiab txuas ob kawg nrog ob lub tooj liab electrodes.Cov electrodes no yog disc-zoo li tus thiab tig raws li cov khoom hla ntawm lawv.Qhov no tso cai rau cov electrode kom muaj kev sib cuag nrog cov khoom siv rau lub sijhawm ntev ntawm kev sib txuas txuas ntxiv.Kev nce qib ntawm vuam tshuab txuas ntxiv txhim kho cov txheej txheem no.
ERW yeeb nkab yog ib qho kev lag luam thiab siv tau zoo rau cov yeeb nkab seamless steel, uas yog qhov ruaj khov dua SAW yeeb nkab.Piv nrog rau cov txheej txheem hnyav siv nyob rau hauv submerged arc welded yeeb nkab, qhov tsis xws luag kuj tsis zoo li tshwm sim, thiab qhov ncaj weld tsis xws luag tuaj yeem tshawb pom tau yooj yim los ntawm ultrasonic xav lossis pom kev.
Txoj kab uas hla ntawm ERW yeeb nkab yog li ntawm nti (15 hli) txog 24 ntiv tes (21.34 hli).
Submerged arc welded yeeb nkab
LSAW (ncaj seam welding) thiab SSAW (kauv seam vuam) yog txawv ntawm submerged arc welded yeeb nkab.Lub submerged arc vuam txheej txheem ua kom muaj qhov siab tam sim no kom tiv thaiv kev nrawm nrawm ntawm flux txheej thiab tsom rau hauv qhov chaw vuam.
Qhov sib txawv tseem ceeb ntawm LSAW thiab SSAW kav yog cov kev taw qhia ntawm cov vuam, uas yuav cuam tshuam rau lub peev xwm ntawm lub siab thiab qhov yooj yim ntawm kev tsim khoom.LSAW yog siv rau nruab nrab-voltage mus rau high-voltage daim ntaub ntawv, thiab SSAW yog siv rau cov kev siv hluav taws xob tsawg.LSAW kav yog kim dua SSAW kav.
Longitudinal submerged arc welded yeeb nkab
LSAW yeeb nkab yog tsim los ntawm kev ua kom kub dov coil steel pwm rau hauv lub tog raj kheej thiab txuas ob qhov kawg ua ke los ntawm cov kab vuam.Qhov no tsim ib tug longitudinally welded yeeb nkab.Cov kav dej no feem ntau yog siv rau cov kav xa mus ntev ntawm cov roj, cov nkev roj, cov thee ua kua, hydrocarbons, thiab lwm yam.
Muaj ob hom LSAW kav: ib leeg-ntev seam thiab ob chav seam (DSAW).LSAW steel yeeb nkab sib tw nrog seamless steel yeeb nkab thiab 16 mus rau 24 nti ERW steel yeeb nkab.Hauv kev lag luam roj thiab cov nkev, cov kav dej loj API 5L LSAW yog siv rau kev thauj mus los ntev thiab muaj txiaj ntsig zoo ntawm hydrocarbons.
Txoj kab uas hla ntawm LAW yeeb nkab feem ntau yog nruab nrab ntawm 16 ntiv tes thiab 60 ntiv tes (406 hli thiab 1500 hli).

SSAW tub
SSAW steel yeeb nkab yog tsim los ntawm dov thiab vuam steel sawb nyob rau hauv kauv los yog kauv kev taw qhia kom lub vuam mus rau hauv kauv.Cov txheej txheem kauv vuam ua rau nws muaj peev xwm tsim cov khoom loj-inch.Kauv steel kav tsuas yog siv rau kev sib kis ntawm cov kua dej tsis tshua muaj siab, xws li cov kav dej hauv cov chaw sab nrauv, cov nroj tsuag petrochemical lossis cov chaw tsim khoom, nrog rau cov vaj tse thiab cov piling.
Cov yeeb nkab txoj kab uas hla ntawm SSAW feem ntau yog 20 ntiv mus rau 100 ntiv tes (406 hli txog 25040 hli).
Yuav ua li cas xaj steel kav rau koj qhov project
Thaum xaj cov kav hlau steel, muaj ob qhov loj me: nominal yeeb nkab loj (NPS) thiab phab ntsa thickness (seem).Rau cov kav dej tsawg dua 4 ntiv tes, cov yeeb nkab ntev tuaj yeem yog ib qho random (SRL) 5-7 meters, lossis rau cov kav dej ntau dua 4 ntiv tes, cov yeeb nkab ntev tuaj yeem ua ob npaug (DRL) 11-13 meters.Kev cai ntev yog muaj rau cov kav dej ntev.Cov yeeb nkab kawg tuaj yeem yog bevel (be), dav hlau (pe), xov (THD) xov thiab coupling (T&C) lossis zawj.
Cov ntsiab lus ntawm kev txiav txim ib txwm:
Hom (seamless los yog welded)
Nominal yeeb nkab loj
Teem caij
Hom kawg
Cov ntaub ntawv qib
Kom muaj nuj nqis nyob rau hauv meters los yog taw los yog tons.
