Shipbuilding Steel Phaj

 

Shipbuilding steel phaj yog ib qho tshwj xeeb, siab -cov hlau zoo tsim los tsim cov nkoj hauv hiav txwv, muab qhov tshwj xeeb lub zog, tawv, thiab corrosion tsis kam tiv taus dej hiav txwv hnyav, cov nthwv dej loj, thiab cov dej qab ntsev ib puag ncig, nrog rau cov qib zoo li A, B, D, E, AH36, DH36, thiab EH36 ntsib cov qauv nruj ntawm cov qauv tsim tawm.

 

 

Shipbuilding steel phaj yog ib hommarine structural hlautshwj xeeb tsim rau nkoj hulls thiab offshore qauv. Piv nrog cov qauv hlau zoo tib yam, nws nta:

• Siab tensile zog
• Zoo heev low -kub tej yam toughness
• Zoo weldability
• Resistance rau seawater corrosion thiab qaug zog

Cov khoom no ua rau lub nkoj tsim cov hlau phaj haum rau ntev - kev pabcuam hauv qabdynamic loads, qis kub, thiab corrosive marine tej yam kev mob.

 

Shipbuilding Steel Classification:

Shipbuilding steel phaj tuaj yeem muab faib ua lub zog dav dav hlau thiab lub zog muaj zog steel raws li nws qhov tsawg kawg nkaus qhov taw qhia lub zog.

 

GNEE Steel cov khoom siv thiab xa tawm 2 hom nkoj steel, nruab nrab lub zog shipbuilding phaj thiab siab zog shipbuilding phaj. Tag nrho cov hlau phaj khoom tuaj yeem tsim tau raws li Society LR, ABS, NK, GL, DNV, BV, KR, RINA, CCS, thiab lwm yam.

 

 

 

Shipbuilding Steel Phaj Development

Shipbuilding yuav tsum muaj ntau ntawm cov qauv steel phaj los tsim rau lub nkoj hull. Nkoj steel tau tsim rau hauv 2 series: siab zog thiab corrosion resistant steels rau niaj hnub shipbuilding, uas yuav txo tau lub nkoj nyhav raws li zoo raws li cov nqi tu. GNEE Steel muaj peev xwm muab lub zog siab steel phaj rau loj ntim nkoj tsim.

 

 

 

 

Shipbuilding ib txwm siv cov txheej txheem steel phaj los tsim cov nkoj hulls. Niaj hnub nimno steel phaj muaj zog tensile ntau dua li lawv cov neeg ua ntej, ua rau lawv zoo dua rau kev tsim kho ntawm cov thawv loj loj. Ntawm no yog qhov zoo ntawm Shipbuilding Phaj Siab corrosion resistant steel phaj yog zoo meej steel hom rau cov roj tso tsheb hlau luam, thiab thaum siv nyob rau hauv shipbuilding, lub nkoj nyhav tsawg dua rau tib lub peev xwm ships, roj nqi thiab CO2 emission yuav txo tau.

 

Cov shipbuilding steel kuj tseem siv tau rau cov qauv sab nrauv, yog tias koj tab tom nrhiav shipbuilding steel phaj lossis offshore qauv steel phaj, Hu rau ANSON tam sim no rau cov lus tshaj tawm.

1. Cov ntsiab lus tseem ceeb ntawm Nkoj Hull Structures

Qhov no yog thawj daim ntawv thov scenario ntawm shipbuilding steel phaj, npog cov qauv tseem ceeb ntawm sab nrauv mus rau sab hauv ntawm lub nkoj:

Cov phaj hauv qab: High-lub zog AH32/AH36 qib steel phaj raug xaiv los tiv thaiv hydrostatic siab thiab cuam tshuam los ntawm seabed reefs. Lawv yuav tsum tau muaj zog yield zog thiab corrosion kuj, nrog ib tug raug thickness ntawm 12mm-30mm;

Hull sab phaj: Tiv thaiv lateral yoj cuam tshuam thiab seawater corrosion. DH32 / DH36 qib steel daim hlau yog siv rau lawv lub zog sib npaug thiab tawv, haum rau qhov hnyav navigation ib puag ncig ntawm dej hiav txwv - mus nkoj;

Deck daim hlau: Dais qhov hnyav ntawm cov khoom thauj, khoom siv, thiab cov neeg ua haujlwm, yuav tsum tau hnav tsis kam thiab qaug zog. EH36 qib steel phaj feem ntau siv, nrog tuab txog 16mm-40mm nyob ntawm lub nkoj tonnage;

Bulkheads thiab keels: Raws li cov khoom thauj-cov kabmob thiab cov qauv sib faib dej tsis sib haum ntawm lub cev, kev sib xyaw ua ke ntawm lub zog siab thiab siab tawv (piv txwv li, EH36+FH36) tau txais los ua kom lub cev tsis muaj dej thiab ruaj khov.

 

2. Marine Engineering Equipment Manufacturing

Tshaj li ntawm cov nkoj, nkoj tsim steel phaj yog dav siv nyob rau hauv marine engineering lug, tshwj xeeb tshaj yog haum rau siab - kev nyuaj siab thiab siab -corrosion offshore ib puag ncig:

Offshore platforms: Nrog rau cov decks, ob txhais ceg, thiab lub tsho ntawm qhov drilling platforms thiab ntau lawm platforms. EH36/FH40 qib tuab daim hlau (thickness 50mm-150mm) raug xaiv los tiv thaiv cua, nthwv dej, thiab dej hiav txwv tam sim no cuam tshuam, nrog rau kev yaig dej hiav txwv ntev;

Subsea pipelines thiab risers: Tsawg- alloy shipbuilding steel daim hlau nrog kev txhim kho corrosion kuj yog siv, ua ke nrog los tiv thaiv -corrosion coatings, rau cov qauv kev txhawb nqa ntawm tob- hiav txwv roj thiab roj xa mus kav;

Offshore cua turbine foundations: Dais qhov hnyav ntawm cua turbines, cua loads, thiab yoj cuam tshuam. Siab - lub zog shipbuilding steel daim hlau yog siv los tsim cov pawg thiab cov kaus mom, kom ntseeg tau ntev - lub sij hawm kev ruaj ntseg.

 

3. Cov xwm txheej tshwj xeeb rau Customized Ships

Targeting tus kheej xav tau ntawm ntau hom nkoj, nkoj tsim steel phaj muab kev daws teeb meem:

LNG cab kuj: Txhawm rau thauj cov roj ntsha cryogenic liquefied ntawm -165 degree, FH36 / FH40 qib ultra-low kub toughness steel daim hlau raug xaiv los xyuas kom meej tias tsis muaj kev puas tsuaj hauv cov cheeb tsam cryogenic thiab zoo vuam nruj;

Icebreakers/polar nkoj: Kev khiav hauj lwm hauv cov dej khov nab kuab, FH40 qib ultra- siab zog steel daim hlau (yield zog Ntau dua los yog sib npaug rau 390MPa) yog siv nrog thickened tsim (thickness 30mm-60mm) los tiv thaiv dej khov extrusion thiab kev sib tsoo;

Thawv nkoj / bulk carriers: Ua raws li kev thauj khoom siab thiab roj efficiency, AH36 / EH36 qib sib sib zog nqus siab - lub zog steel daim hlau raug xaiv los txo lub cev hnyav thaum ua kom lub cev muaj zog, txhim kho lub peev xwm thauj khoom.

 

4. Chaw nres nkoj Machinery thiab Marine Auxiliary Equipment

Chaw nres nkoj cranes thiab thawv gantry cranes: Cov kab teeb tseem ceeb, ob txhais ceg, thiab lwm yam thauj khoom -cov kabmob yog tsim los ntawm cov nkoj tsim steel phaj, leveraging nws lub zog siab thiab qaug zog tiv thaiv kom haum rau qhov cuam tshuam ntawm kev nqa ntau zaus;

Nkoj spare qhov chaw thiab tu: Siv nyob rau hauv lub nkoj deck renovation, hull welding kho, alarm hloov, thiab lwm yam kev tu ncua scenarios. Cov qib steel thiab cov lus qhia tshwj xeeb sib piv rau thawj lub nkoj tau muab los ua kom cov txheej txheem sib xws tom qab kho.
