Lub liquefaction kub ntawm cov roj ntuj yog -162 degree, thiab qhov ntim ntawm liquefied natural gas (LNG luv luv) yog 1/600 ntawm lub xeev gaseous, uas tso siab rau cov khoom ntawm LNG cia tso tsheb hlau luam. Feem ntau hais lus, cov phab ntsa sab nrauv yog ua los ntawm cov pob zeb ua kom muaj zog, thiab cov phab ntsa hauv lub tank yuav tsum tau tiv taus qhov kub thiab txias, thiab feem ntau yog ua los ntawm cov ntaub ntawv xws li 9Ni steel lossis aluminium alloy. Ntawm lawv, feem ntau ntawm cov txhuas alloys siv hauv LNG cia tso tsheb hlau luam yog 5 series 5083 txhuas daim hlau. Yog vim li cas 5083 txhuas daim hlau tuaj yeem "ua haujlwm tseem ceeb" yog vim nws muaj cov yam ntxwv hauv qab no:
5083 txhuas phaj belongs rau AL-Mg series alloy, nrog tsawg ntom, siab zog, zoo qaug zog kev ua tau zoo thiab vuam kev ua tau zoo, thiab zoo kuj rau marine atmospheric corrosion. Lub zog tensile nyob nruab nrab ntawm 290-345Mpa thiab lub zog tawm los yog nruab nrab ntawm 145-283Mpa. 5083 txhuas phaj yog siv rau hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv corrosion, zoo weldability thiab nruab nrab lub zog, xws li nkoj thiab tsheb. Nws tseem tuaj yeem siv rau hauv cov hlab ntsha siab, chav tub yees, TV yees, cov khoom siv drilling, thiab cov khoom siv thauj mus los uas yuav tsum tau muaj kev tiv thaiv hluav taws nruj heev. tos.
Raws li cov ntaub ntawv los ntawm National Development thiab Reform Commission, kuv lub teb chaws kev siv roj av txuas ntxiv, nrog qhov nruab nrab txhua xyoo kev loj hlob ntawm kwv yees li 15%. Kev txwv los ntawm tag nrho cov khoom siv hluav taws xob hauv tsev thiab cov peev txheej mining, lub neej yav tom ntej hauv kev xav tau cov pa roj carbon monoxide feem ntau yuav raug sau los ntawm LNG ntshuam. Nws tuaj yeem pom tau tias qhov kev thov rau LNG cia tso tsheb hlau luam yav tom ntej yuav tsis tuaj yeem kwv yees. Raws li cov khoom siv raw los ua LNG cia tso tsheb hlau luam, "yav tom ntej" ntawm 5083 txhuas daim hlau tsis muaj kev txwv.
