DNV DH36 Marine Steel Phaj

DNV steel phaj DH36 txawv ntawm lwm qib ntawm steel phaj nyob rau hauv ntau txoj kev:

 

Mechanical Properties:Lub zog:

Yield zog: Lub zog tawm los ntawm DH36 yog qhov siab, feem ntau tsawg kawg yog 355 MPa. Qhov no yog siab tshaj ntau qib ntawm cov hlau, tso cai rau nws kom zoo dua tiv thaiv cov loads thiab kev ntxhov siab nyob rau hauv marine thiab offshore daim ntawv thov yam tsis tau dhau deformation ntau dhau. Piv txwv li, piv rau cov hlau me me nrog lub zog qis dua, DH36 tuaj yeem tuav qhov hnyav thiab lub zog muaj zog ntawm lub nkoj loj lub nkoj los yog lub platform offshore zoo dua.

Tensile zog: Nws muaj lub zog tensile nyob rau hauv thaj tsam ntawm 490 - 620 MPa, qhia tias nws muaj peev xwm tiv thaiv tau rub tawm los yog tawg hauv qhov nro. Lub zog tensile siab no yog qhov tseem ceeb rau kev tiv thaiv ntau lub zog uas tau ntsib nyob rau hauv marine ib puag ncig, xws li kev cuam tshuam yoj, cua loads, thiab cov kev ntxhov siab thaum lub sij hawm ua hauj lwm ntawm ships los yog offshore lug.

Toughness: DH36 paub txog nws zoo toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub. Nws tuaj yeem nqus tau ntau lub zog ua ntej tawg, uas yog qhov tseem ceeb rau kev siv hauv qhov chaw txias dej hiav txwv lossis qhov chaw muaj kev pheej hmoo ntawm kev cuam tshuam. Qhov no yog qhov sib piv rau lwm qib ntawm cov hlau uas tuaj yeem ua rau qhov kub thiab txias thiab tsis haum rau qhov xav tau ib puag ncig.

Tshuaj muaj pes tsawg leeg:

Alloying Elements: DH36 muaj cov ntsiab lus alloying tshwj xeeb hauv kev tswj xyuas kom zoo kom ua tiav nws cov khoom xav tau. Piv txwv li, nws muaj cov ntsiab lus manganese nyob rau hauv thaj tsam ntawm 0.90 - 1.60%, uas ua rau nws lub zog thiab tawv. Lub xub ntiag ntawm lwm cov ntsiab lus xws li carbon, silicon, phosphorus, thiab leej faj kuj raug tswj nyob rau hauv cov kev txwv tshwj xeeb los xyuas kom meej cov hlau zoo thiab kev ua tau zoo.

Cov cheeb tsam thov:

Marine thiab Offshore Industry Focus: DH36 tshwj xeeb yog tsim los siv rau hauv kev lag luam marine thiab offshore. Nws yog feem ntau siv rau hauv kev tsim cov nkoj hulls, offshore roj drilling platforms, platform yeeb nkab pob qij txha, thiab lwm yam khoom uas yuav tsum tau muaj zog, toughness, thiab corrosion kuj nyob rau hauv marine ib puag ncig.

Kev siv hnyav hnyav: Vim nws lub zog siab thiab kev ua haujlwm zoo, DH36 yog qhov tsim nyog rau cov ntawv thov uas muaj cov khoom hnyav thiab cov kev xav tau tam sim no. Piv txwv li, nws yog siv rau hauv cov nkoj loj hauv hiav txwv nrog kev hloov pauv ntau dua 10, 000 tons, qhov twg cov qauv kev ncaj ncees ntawm lub nkoj yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm ntawm lub nkoj.

Certification thiab Standards: DH36 yog tsim nyob rau hauv kev pom zoo thiab ntawv pov thawj ntawm DNV (Det Norske Veritas), ib pawg neeg saib xyuas hauv kev lag luam marine thiab offshore. Qhov no txhais tau hais tias cov hlau ua tau raws li cov qauv kev ua tau zoo thiab kev ua tau zoo los ntawm DNV, ua kom nws txoj kev ntseeg siab thiab tsim nyog rau kev siv hauv kev siv marine thiab offshore. Lwm qib ntawm cov hlau tuaj yeem raug lees paub los ntawm cov koom haum sib txawv los yog yuav tsis ua raws li cov qauv nruj raws li DH36.
