Q: Vim li cas nws thiaj haum rau LNG (Liquefied Natural Gas) daim ntawv thov?
A:Nws zoo heev uas tsis tshua muaj - qhov kub thiab txias ua rau nws zoo- haum rau kev thauj thiab khaws cia cov xov xwm cryogenic xws li LNG -3-4.
Q: Puas yog A333 Gr.6 siv hauv kev tsim hluav taws xob?
A:Yog lawm, nws yog siv los thauj cov dej qis qis, xws li cov kua nitrogen, uas txhawb nqa kev ua haujlwm ntawm qee yam khoom siv hluav taws xob -4.
Q: Cov khoom no puas tuaj yeem siv rau hauv nuclear fais fab nroj tsuag?
A:Yog lawm, SA333 Gr-6 steel yog siv nyob rau hauv cov qauv ntawm nuclear fais fab nroj tsuag, piv txwv li, raws li cov thawj tshav kub thauj yeeb nkab rau Heavy Water Gas-Cooled Reactors (HWGCR) -8. Txawm li cas los xij, cov txheej txheem vuam tshwj xeeb yuav tsum tsim nyog kom ua tau raws li cov cai nruj xws li ASME IX thiab III -8.
Q: Dab tsi yog qhov kev tsim tshwj xeeb rau ASTM A333 Qib 6 yeeb nkab?
A:Cov txheej txheem tsim khoom yuav tsum muaj kev tswj hwm nruj, suav nrog kev siv cov ntaub ntawv pov thawj los ntawm cov hlau loj loj, cov txheej txheem kev kho cua sov tshwj xeeb, thiab nruj tsis yog{0}} kev ntsuas kev puas tsuaj kom ntseeg tau tias qhov ua tau zoo ntawm qhov kub thiab txias -1.
Q: Vim li cas ho tsis muaj qhov toughness tseem ceeb rau cov yeeb nkab no?
A:Notch toughness yog lub peev xwm ntawm cov khoom siv los nqus lub zog thiab tiv thaiv kev puas tsuaj ntawm qhov muaj qhov tsis zoo lossis qhov ntsuas kub qis, uas yog qhov laj thawj tseem ceeb rau qhov kev qhia tshwj xeeb no.
