Qhov sib txawv ntawm DNV E36 thiab DNV E32 - Kev Paub

DNV E36 yog ib qho muaj zog, siab tshaj -yield steel dua DNV E32, siv rau kev xav tau ntau cov qauv marine, muab lub zog ntau dua (ib puag ncig 360 MPa tawm los) thiab cuam tshuam rau qhov kub thiab txias, thaum E32 yog cov hlau uas muaj zog (nyob ib ncig ntawm 315 MPa yield) rau kev tsim nkoj dav dav, nrog rau kev ua haujlwm qis dua (E36) -20℃vs . -30℃lossis qis dua rau E32). Lub "36" thiab "32" hais txog qhov tsawg kawg nkaus lub zog (hauv MPa), thiab "E" qhia txog qhov tsim nyog rau qhov kub tsis tshua muaj, nrog E36 muaj cov khoom zoo tshaj plaws rau kev siv harsher offshore / Arctic.

Daim ntawv thov:
E32: General nkoj tsim, bulkheads, decks.
E36: Lub zog xav tau ntau dua hauv kev tsim cov nkoj, cov chaw sab nrauv, cov chaw txawb, qhov chaw hnyav.
Toughness (Charpy Impact):
E36: Zoo dua qis- qhov kub thiab txias cuam tshuam (feem ntau kuaj ntawm -20℃lossis qis dua) rau cov mob txias dua, raws li DNV cov cai.
E32: Tus qauv qis-kub toughness (xws li -30℃).
Kev faib tawm: Ob qho tib si yog ib feem ntawm DNV tsev neeg (tam sim no tau koom ua ke nrog GL, feem ntau VL/DNV-GL), nrog rau tsab ntawv ua ntej (A, D, E, F) qhia tias tsim nyog rau cov ntawv thov sib txawv, tab sis tus lej yog qhov sib txawv ntawm qhov tseem ceeb.
Hauv Cov Ntsiab Lus Yooj Yim: Xav txog E36 yog qhov hnyav dua, muaj zog dua tus kwv tij rau E32, ua kom tiv taus txias dua, xav tau ntau dua ntawm ntug dej hiav txwv lossis Arctic hauv nkoj thiab cov qauv.
