Covcev steelmuaj ntau heev nyob rau hauv marine engineering.Ob lub tshuab ntawm nkoj thiab marine engineering xav tau roughly nyob rau hauv peb hom steel yeeb nkab: steel yeeb nkab nyob rau hauv cov pa system, tsim nrog steel kav thiab tshwj xeeb lub hom phiaj steel kav.

steel yeeb nkab nyob rau hauv cov pa system.
Txawv nkoj thiab marine engineering, ob qho tib si pa system muaj lub siab ua haujlwm.
Nkoj kev pab cuam lub neej ntawm 20 xyoo.Ntau yam ntawm cov pa system, bilge dej, ballast, dewater dej phwj, cua, ntsuas, txhaj tshuaj, dej hauv tsev, hluav taws, cargo roj stripping, breathable, inert gas, cua sov, ntxuav, ua npuas ncauj extinguishing sprinkler, vapor, kua theem telemetry, valve chaw taws teeb. tswj systems, tshwj xeeb ships kuj muaj xws li ib tug mob siab rau kev thauj mus los ntawm liquefied petroleum gas (LPG), liquefied natural gas (LNG).Marine engineering kev pabcuam lub neej txog li 30 xyoo, lossis ntev dua.Marine engineering ntxiv rau cov pa system, tshwj xeeb cov cuab yeej siv drilling, roj av / LPG / LNG ua haujlwm ua haujlwm, tshwj xeeb mooring system, flare system, thiab lwm yam.Nws tau raug txheeb cais, nkoj yeeb nkab txhua xyoo noj ntawm 450 lab tons, txog 440,000, nws cov qauv yog GB, YB, CB, 70% ntawm cov yeeb nkab steel txuas.Tsuas yog 30-tuj cov roj av loj heev rau cov nqi txog li kaum mais, tsuas yog siv cov yeeb nkab steel (xws li), muaj txog li 1,500 tons, tau kawg, qhov nyiaj ntawm 40,000 tons txheeb ze rau cov qauv hull lossis txwv.Tsis tas li ntawd, coj mus rau hauv tus account tib lub nkoj, mus rau kev tsim cov nkoj, nrog rau ntau lwm lub nkoj, yog li qhov kev siv ntau npaum li cas kuj yog ntau.Thiab 300,000 tons-chav kawm tus naj npawb ntawm cov yeeb nkab FPSO loj tshaj 30,000, ntau dua 90 km ntev, uas yog tib lub tonnage theem 2 txog 3 zaug.Yog li ntawd, kev lag luam shipbuilding tau dhau los ua tus neeg siv khoom loj ntawm kev lag luam steel yeeb nkab.

Hlau yeeb nkab hauv kev tsim
Steel raj marine engineering daim ntaub ntawv, ntxiv rau saum toj no cov pa system nrog ib tug mob siab rau system, muaj ntau tsim ib tug loj tus naj npawb ntawm steel kav, xws li lub tsho, underwater steel piles, Casing, mooring bracket, nyoob hoom qav taub platform, hluav taws xob ntauwd.Hom steel yeeb nkab, cov khoom specifications, nrog tib txoj kab uas hla, reducers, txawv phab ntsa thickness, raws li zoo raws li ib tug loj tus naj npawb ntawm Y, K, T-tswj nodes.Xws li lub tsho, steel pawg, lub tes tsho lub taub hau tsis zoo, feem ntau cov kab loj loj steel yeeb nkab loj, feem ntau yog ua los ntawm cov hlau dov.Lawv cov khoom siv rau E36-Z35, D36-Z35, E36, D36.Cov qauv steel yeeb nkab tsis muaj YB, CB, thiab feem ntau yog GB712-2000.Kev tsim cov yeeb nkab steel steel yeeb nkab raug xyaum SY / T10002-2000 tsim los ntawm Tuam Tshoj Petroleum Industry Standards and Technology Commission (CPSC).Txij li thaum Tuam Tshoj tsis muaj cov chaw lag luam tshwj xeeb, feem ntau yog kev yuav cov phaj steel los ntawm kev tsim kho, cov txheej txheem molding tus kheej.

Cov yeeb nkab steel rau lub hom phiaj tshwj xeeb
Lub hom phiaj tshwj xeeb steel tshwj xeeb steel yeeb nkab siv hauv qhov chaw ua haujlwm tshwj xeeb thiab nruab nrab ua haujlwm.Undersea pipeline yog cov tshwj xeeb steel yeeb nkab, qhov kev thov kom loj dua, siab zog, me me kam rau ua, zoo corrosion kuj.Tam sim no, cov kav dej ntau lawm tsuas yog nyob rau hauv nws cov me nyuam mos, vim hais tias cov khoom siv vuam, corrosion kuj los yog tsawg Specifications (inch thiab phab ntsa thickness), kim, thiab lwm yam .. Tuam Tshoj tus offshore crude roj xav tau kev thauj mus los.Yav dhau los, siv ob chav yeeb nkab rwb thaiv tsev qauv, muaj kev nyab xeeb thiab txhim khu kev qha.Tab sis raws li kev tiv thaiv cov yeeb nkab steel yeeb nkab yog kev lag luam zoo heev, thiab cov yeeb nkab tawm sab nrauv tso tawm dhau los, yuav tsum tau ua cov yeeb nkab txuas sab hauv thiab sab nraud, txo qhov ua tau zoo ntawm cov yeeb nkab tso, ua rau cov nqi installation nce exponentially.Nyob rau hauv lub xyoo pua 21st, nws tau launched ib tug pob zeb counterweight steel yeeb nkab.Nws cov qauv yog (los ntawm sab hauv mus rau sab nraud): anti-corrosion txheej steel, epoxy hmoov (FBE), polyurethane rwb thaiv tsev, polyethylene (PE) lub tsho tube, ntxiv dag zog rau pob zeb counterweight txheej (lub sab hauv configuration ntawm steel mesh).Hom hlau tshwj xeeb no, Tuam Tshoj tau tuaj ntawm txawv teb chaws, xws li Bohai Penglai 19-3 roj teb, ib qhov project siv Malaysian BREDEROPRICE tuam txhab cov khoom.Tuam Tshoj tom qab kev tshawb fawb thiab kev sim, thiab nyob rau hauv 2002 ua nyob rau hauv Tanggu, Tuam Tshoj tus thawj pob zeb nrog hnyav steel yeeb nkab ntau lawm kab, muaj ntau txhiab kilometers ntawm pipelines rau offshore oilfield khoom.Nws tau tshaj tawm tias, siv cov hlau no hauv ib kilometer subsea pipeline los txo tus nqi ntawm 50 lab mus rau 100 lab, thiab txo tus nqi ntawm kev loj hlob ntawm ntug dej hiav txwv zoo heev, yog li ntawd ntau cov roj marginal yuav raug nqi los tsim.
