Aluminium alloys nyob rau hauv daim ntawv thov ntawm offshore helicopter platforms
Hlau feem ntau yog siv los ua cov khoom siv tseem ceeb hauv cov roj av drilling platforms vim nws lub zog siab. Txawm li cas los xij, nws ntsib teeb meem xws li corrosion thiab lub neej luv luv thaum raug rau ib puag ncig marine. Hauv kev tsim kho vaj tse rau kev tsim kho cov roj av thiab roj av, qhov dav hlau tsaws dav hlau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa lub dav hlau ya dav hlau thiab tsaws, ua qhov tseem ceeb txuas rau thaj av loj. Aluminium-made helicopter lawj modules yog dav siv vim lawv hnav, muaj zog zoo thiab nruj, thiab ua tau raws li qhov tsim nyog ua haujlwm.
Aluminium alloy nyoob hoom qav taub platforms muaj ib lub thav duab thiab lub lawj ua los ntawm kev sib sau ua ke ntawm aluminium alloy profiles nrog tus ntoo khaub lig-sectional zoo li tsab ntawv "H," nrog ribbed phaj kab noj hniav nyob nruab nrab ntawm lub sab sauv thiab qis lawj daim hlau. Los ntawm kev siv lub hauv paus ntsiab lus ntawm mechanics thiab khoov lub zog ntawm aluminium alloy profiles, lub platform ua tau raws li qhov yuav tsum tau ua thaum txo nws tus kheej qhov hnyav. Tsis tas li ntawd, nyob rau hauv ib puag ncig marine, aluminium alloy nyoob hoom qav taub platforms yooj yim los tswj, muaj kev tiv thaiv corrosion zoo, thiab, ua tsaug rau lawv cov qauv tsim profile, tsis tas yuav vuam. Qhov tsis muaj vuam no tshem tawm qhov chaw kub ntxhov uas cuam tshuam nrog vuam, ua kom lub neej ntev ntawm lub platform thiab tiv thaiv tsis ua haujlwm.
Daim ntawv thov ntawm aluminium alloys hauv LNG (Liquefied Natural Gas) cargo nkoj
Raws li kev tsim cov roj av thiab roj av txuas ntxiv mus, ntau thaj chaw loj thiab cov chaw xav tau nyob deb deb thiab feem ntau sib cais los ntawm cov dej hiav txwv loj. Yog li ntawd, lub hom phiaj tseem ceeb ntawm kev thauj cov roj ntsha liquefied yog los ntawm cov nkoj mus hauv hiav txwv. Kev tsim ntawm LNG nkoj cia tso tsheb hlau luam yuav tsum muaj cov hlau uas muaj qhov ua tau zoo ntawm qhov kub thiab txias, nrog rau lub zog txaus thiab tawv. Aluminium alloy cov ntaub ntawv muaj lub zog ntau dua ntawm qhov kub thiab txias piv rau hauv chav tsev kub, thiab lawv cov khoom sib sib zog nqus ua rau lawv zoo tagnrho rau kev siv hauv marine cua, qhov chaw uas lawv tiv taus corrosion.
Hauv kev tsim cov nkoj LNG thiab LNG cia tso tsheb hlau luam, 5083 aluminium alloy yog dav siv, tshwj xeeb tshaj yog nyob rau hauv Nyiv, ib qho ntawm cov loj tshaj plaws importers ntawm liquefied natural gas. Nyiv tau tsim cov LNG tso tsheb hlau luam thiab thauj nkoj txij li xyoo 1950 thiab 1960s, nrog cov qauv ntawm lub cev tseem ceeb ua los ntawm 5083 txhuas alloy. Feem ntau aluminium alloys, vim lawv lub teeb yuag thiab corrosion-resistant zog, tau dhau los ua cov ntaub ntawv tseem ceeb rau cov qauv saum toj kawg nkaus ntawm cov tso tsheb hlau luam. Tam sim no, tsuas yog ob peb lub tuam txhab thoob ntiaj teb tuaj yeem tsim cov khoom siv hluav taws xob qis qis rau LNG thauj nkoj cia tso tsheb hlau luam. Nyiv lub 5083 txhuas alloy, nrog ib tug tuab ntawm 160 hli, exhibits zoo heev uas tsis muaj kub toughness thiab qaug zog kuj.
Kev siv cov aluminium alloys hauv cov khoom siv nkoj nkoj
Shipyard khoom xws li gangways, floating choj, thiab taug kev yog fabricated los ntawm 6005A los yog 6060 aluminium alloy profiles los ntawm vuam. Floating docks yog tsim los ntawm welded 5754 aluminium alloy daim hlau thiab yuav tsum tsis txhob pleev xim los yog tshuaj kho mob vim lawv cov dej tsis sib haum.
Aluminium alloy laum yeeb nkab
Aluminium Alloy Laum Kav yog lub zog qis, lub zog ua kom muaj zog, txo cov kev sib zog, thiab cov txhuam hniav tsis kam tiv thaiv cov phab ntsa zoo. Thaum lub tshuab drilling lub peev xwm tso cai, kev siv aluminium alloy laum kav dej tuaj yeem ua tiav qhov tob tob uas cov yeeb nkab steel laum tsis tuaj yeem. Aluminium alloy laum cov kav dej tau ua tiav hauv kev tshawb nrhiav roj av txij li xyoo 1960, nrog kev siv dav hauv lub qub Soviet Union, qhov chaw uas lawv mus txog qhov tob ntawm 70% mus rau 75% ntawm tag nrho qhov tob. Kev sib koom ua ke ntawm qhov zoo ntawm kev ua haujlwm siab aluminium alloys thiab tsis kam rau seawater corrosion, aluminium alloy laum kav dej muaj peev xwm tseem ceeb hauv marine engineering ntawm offshore drilling platforms.
