Liquefaction kub ntawm cov nkev yog -162 ° C, Aluminium rau kev lag luam thiab qhov ntim ntawm liquefied natural gas (LNG rau luv) yog 1/600 ntawm lub xeev gaseous, Aluminium rau kev lag luam uas ua rau cov khoom xav tau rau LNG cia tso tsheb hlau luam ntau dua. Feem ntau hais lus, sab nrauv tank phab ntsa yog prestressed reinforced ua vaj tse, Txhuas rau kev lag luam thiab lub tank tank sab hauv yuav tsum kub tsis tshua muaj kev ua haujlwm.
Feem ntau, Txhuas rau cov khoom siv kev lag luam xws li 9Ni steel lossis aluminium alloy siv. Ntawm lawv, feem ntau ntawm cov txhuas alloys siv rau LNG cia tso tsheb hlau luam yog 5 series 5083 txhuas phaj. Vim li cas 5083 txhuas phaj tuaj yeem" coj lub luag haujlwm no" feem ntau yog vim muaj cov yam ntxwv hauv qab no:
5083 txhuas ntawv yog cov AL-Mg series alloy, nrog cov ntom ntom, Aluminium rau kev lag luam siab lub zog, ua haujlwm zoo ntawm lub cev thiab vuam kev ua tau zoo, Aluminium rau kev lag luam thiab zoo tsis kam mus rau marine atmospheric corrosion.
Lub zog tensile yog nruab nrab ntawm 290-345Mpa thiab qhov tawm ntawm lub zog yog li ntawm 145-283Mpa. 5083 txhuas ntawv yog siv qee zaus uas yuav tsum muaj cov tshuaj tiv thaiv corrosion, Aluminium rau kev lag luam zoo weldability thiab nruab nrab lub zog, Aluminium rau kev lag luam xws li nkoj thiab tsheb, thiab tseem tuaj yeem siv rau hauv cov nkoj siab, cov tub yees, TV yees, Txhuas rau kev lag luam drilling. cov cuab yeej siv, thiab cov khoom siv thauj khoom uas xav tau kev tiv thaiv hluav taws nruj Tos.
