Hauv kev thauj mus los roj thiab roj av niaj hnub no thiab cov haujlwm txuag dej, lub zog thiab kev ntseeg tau ntawm cov kav dej hlau yog qhov tseem ceeb tshaj plaws. Txais tos rau lub ntiaj teb ntawm cov kav hlau carbon uas tau vuam ua ke - cov thev naus laus zis tshiab no tab tom hloov pauv cov toj roob hauv pes ib txwm muaj ntawm kev vuam cov kav hlau. Los ntawm kev dov cov hlau carbon qis-carbon rau hauv cov kav dej ntawm cov ces kaum tshwj xeeb thiab tom qab ntawd ua qhov vuam meej, peb tsim cov khoom zoo uas muaj zog, ruaj khov, thiab ntau yam.
Ntawm ntau hom kav dej hlau,X60 SSAW Kab Yeeb NkabthiabX70 SSAW Kab Yeeb Nkabyog ob yam khoom ua tau zoo uas nyiam heev hauv kev ua lag luam.
Cov Yeeb Nkab X60 SSAW muaj lub zog tsawg kawg nkaus zoo heev (415 MPa) thiab tsim nyog rau cov kav dej roj thiab roj nruab nrab thiab siab. Nws tuaj yeem tiv taus lub zog sab hauv loj thiab cov khoom thauj sab nraud thaum tswj hwm qhov ruaj khov thiab weldability zoo, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ob qho tib si onshore thiab offshore ntev pipeline systems.
Lub X70 SSAW Kab Yeeb Nkab mus ntxiv, nrog rau qhov tsawg kawg nkaus ntawm 485 MPa, ua rau nws tsim nyog rau cov haujlwm thauj mus los hauv qab qhov siab dua thiab qhov chaw xav tau ntau dua. Nws lub zog siab dua tso cai rau kev siv cov phab ntsa nyias dua, yog li txo qhov hnyav ntawm cov kav dej, txo cov nqi thauj mus los thiab kev teeb tsa, thaum tswj hwm qhov zoo tiv thaiv kev hloov pauv thiab tawg.
Ob yam khoom no yog tsim los ntawm kev siv cov txheej txheem vuam kauv. Qhov zoo ntawm kev vuam ruaj khov, kev ua haujlwm zoo, thiab lawv tuaj yeem tsim cov kav hlau loj thiab cov kav hlau tuab, ua tau raws li qhov xav tau tshwj xeeb ntawm ntau yam haujlwm.
Ua ib lub tuam txhab muag khoom, Cangzhou Spiral Steel Pipe Group Co., Ltd. yog ib lub tuam txhab ua cov kav hlau kauv thiab cov khoom siv txheej kav hlau hauv Suav teb. Lub tuam txhab tau tsim tsa xyoo 1993 thiab nyob hauv Cangzhou City, Hebei Province. Nws npog thaj tsam ntawm 350,000 square meters, muaj tag nrho cov cuab tam ntawm 680 lab yuan, thiab tam sim no muaj 680 tus neeg ua haujlwm. Lub tuam txhab tsim tau 400,000 tons ntawm cov kav hlau kauv txhua xyoo thiab muaj tus nqi tsim tawm txhua xyoo ntawm 1.8 billion yuan.
Txawm koj xaiv X60 SSAW Kab Yeeb Nkab rau cov phiaj xwm kev thauj mus los, lossis xaiv X70 SSAW Kab Yeeb Nkab los daws cov teeb meem siab dua, Cangzhou Spiral Steel Pipe Group tuaj yeem muab cov khoom lag luam txhim khu kev qha thiab kev txhawb nqa kev tshaj lij rau koj. Peb cog lus tias yuav siv cov kav hlau zoo los txuas lub zog yav tom ntej ntawm lub ntiaj teb.
Yog tias koj xav paub ntxiv txog cov khoom lossis tau txais cov kev cai, thov koj xav tiv tauj peb txhua lub sijhawm.
