DNV / DH40 steel phaj

DNV / DH40 steel phaj muaj cov yam ntxwv thiab kev siv hauv qab no:

 

Mechanical Properties

 

Lub zog

Yield zog: DH40 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 390 MPa. Qhov no siab yield zog ua rau cov hlau tiv taus qhov tseem ceeb static thiab dynamic loads yam tsis tau dhau mus tas li deformation. Piv txwv li, nyob rau hauv kev tsim kho ntawm cov nkoj loj los yog offshore platforms, cov tswv cuab tsim los ntawm DH40 steel tuaj yeem txhawb nqa qhov hnyav thiab sab nraud tsis muaj buckling lossis deforming.

Tensile zog: Lub zog tensile ntawm DH40 feem ntau yog nyob rau hauv thaj tsam ntawm 510 - 650 MPa. Cov cuab yeej no muab cov hlau uas muaj peev xwm tiv thaiv tau rub tawm los ntawm kev nro, uas yog qhov tseem ceeb hauv cov ntawv thov uas cov hlau raug rau lub zog tensile, xws li nyob rau hauv cov kab mooring lossis cov tswv cuab ntawm cov qauv sab nrauv.

Toughness

DH40 steel phaj muaj zoo heev toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub. Qhov no txhais tau tias nws tuaj yeem nqus tau ntau lub zog ua ntej tawg. Cov cuab yeej no yog qhov tseem ceeb rau kev siv hauv qhov chaw txias lossis qhov chaw muaj kev pheej hmoo ntawm kev cuam tshuam. Piv txwv li, nyob rau hauv Arctic shipping los yog offshore ua hauj lwm nyob rau hauv dej txias, lub toughness ntawm DH40 steel xyuas kom meej tias cov qauv muaj peev xwm tiv taus qhov cuam tshuam ntawm icebergs los yog floating khib nyiab yam tsis muaj kev puas tsuaj loj.

 

 

 

Cov ntawv thov hauv Marine thiab Offshore Industries

 

Shipbuilding

Lub hull ntawm lub nkoj yog ib qho chaw siv loj. DNV / DH40 steel daim hlau muab cov qauv txheej txheem uas muab lub nkoj nws cov duab thiab lub zog. Ntau qhov chaw ntawm lub nkoj, xws li hauv qab, sab, thiab lawj, yog tsim los ntawm qib steel.

Cov txheej txheem sab hauv xws li bulkheads, thav duab, thiab decks kuj yog ua los ntawm DNV / DH40 steel daim hlau los xyuas kom meej tag nrho kev nyab xeeb thiab ruaj khov ntawm lub nkoj.

Offshore Structures

Offshore platforms, drilling rigs, thiab lwm yam marine installation kuj tseem siv tau DNV / DH40 steel daim hlau. Cov qauv no raug cuam tshuam rau cov dej hiav txwv hnyav, thiab cov hlau phaj yog siv los tsim cov qauv tseem ceeb nrog rau ntau yam khoom.

 

 

Specification peb muab:

Thickness	2-200 hli
Dav	1000-4000 hli
Ntev	5000-15000 hli

 

 

Muaj ntau qhov hloov pauv rau DNV steel phaj AH40 / DH40, suav nrog:

 

EH40 steel phaj: Qhov no yog cov qib high-strength steel siv nyob rau hauv shipbuilding thiab offshore daim ntaub ntawv. Nws muaj qhov sib piv txhua yam khoom ntawm lub zog thiab toughness. EH40 kuj ua tau raws li qhov yuav tsum tau ua rau kev xav tau cov qauv hauv hiav txwv thiab sab nrauv, ua rau nws yog qhov tsim nyog rau ntau qhov xwm txheej3.

ASTM A131 AH40 Hlau Phaj: Hauv tus qauv ASTM A131 / A131M, ASTM A131 AH40 yog qib zoo sib npaug steel rau DNV AH40. Nws muaj cov yam ntxwv zoo sib xws thiab kev ua haujlwm zoo, uas tso cai rau nws siv los hloov pauv hauv cov ntawv thov cuam tshuam.

Lwm cov High-Strength Shipbuilding Steel Qib: Qee lwm cov qib high-strength shipbuilding steel qib los ntawm cov kev faib pawg sib txawv, xws li ABS qib AH40, LR qib AH40, NK qib AH40, thiab BV qib AH40, kuj tseem raug suav hais tias yog hloov pauv mus rau qee yam. Cov qib no muaj cov kev xav tau ntawm lub zog zoo sib xws thiab tau lees paub los ntawm cov koom haum sib txawv, tab sis lawv tuaj yeem muab cov kev ua tau zoo sib xws hauv kev tsim khoom hauv nkoj thiab marine engineering.

 

Txawm li cas los xij, thaum xaiv qhov hloov pauv rau DNV steel phaj AH40 / DH40, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov, xws li lub zog, toughness, weldability, thiab corrosion kuj, los xyuas kom meej tias qhov kev xaiv hloov tuaj yeem ua tau raws li tus qauv tsim thiab kev ua tau zoo ntawm cov qauv.
