Qhov sib txawv ntawm LR EH62 thiab LR EH69 steel phaj - Kev Paub

LR EH69 yog qhov siab dua - lub zog, ntxiv - lub zog shipbuilding steel (Yield zog nyob ib ncig ntawm 315-390 MPa ntau, tab sis siab dua EH62) piv rau EH62, tsim los rau ntau xav tau cov qauv siv nyob rau hauv cov hlab ntsha, thaum EH62 (zoo li ib tug laus lub npe los yog qis dua 6 series) nyob rau hauv uas ze rau 4 tier. kev ua tau zoo rau kev dav dav shipbuilding, ob qho tib si ua tau raws li Lloyd's Register (LR) cov qauv tab sis catering rau txawv load yuav tsum.

LR EH69: Qhov no yog qib siab dua -qib, ntxiv- lub zog steel phaj (feem ntau tsuas yog 'EH69'), muab cov txiaj ntsig zoo tshaj plaws los tuav cov khoom tseem ceeb hauv cov qauv hull tseem ceeb, feem ntau siv qhov sib dua thiab lub zog siab dua.

LR EH62: Qhov no yog ib qho muaj zog, dav dav - lub hom phiaj shipbuilding steel, ib feem ntawm 'EH' series tab sis ntawm lub zog qis dua EH69, haum rau kev tsim kho dav dav tab sis tsis yog qhov xav tau ntawm EH69.

Xav txog qhov zoo li no: EH69 zoo li lub log tsheb hnyav - lub luag haujlwm tsheb, thaum EH62 yog lub log tsheb zoo, txhim khu kev qha; ob qho tib si yog cov log tsheb (steel), tab sis ib qho tau tsim rau cov mob hnyav dua.

Key Takeaway: Yog tias koj qhov project xav tau ntau dua load-cov kabmob muaj peev xwm lossis cov khoom siv sib dua, koj yuav xaiv EH69 dhau EH62; rau kev xav tau lub zog dav dav, EH62 yog qhov txaus thiab pheej yig dua.
