Nyob rau hauv niaj hnub shipbuilding thiab offshore engineering industries, cov khoom tsis ua hauj lwm tsis yog ib qho kev xaiv. Thaum tsim lub nkoj hulls, superstructures, los yog offshore platforms, shipyards yuav tsum tau cov ntaub ntawv uas muab siab zog, txhim khu kev qha weldability, thiab kiag li tsis kam mus rau dej ntsev corrosion.
Ntawm tag nrho cov marine{0}} qib alloys, 5083 H116 txhuas phaj sawv tawm raws li tus qauv thoob ntiaj teb. Txawm li cas los xij, muab cov khoom siv no xav tau ntau dua li kev sib ntsib tshuaj lom neeg; nws yuav tsum tau ua raws li txoj cai nruj thiab zoo. Ntawm GNEE, peb muab cov nqi hwm DNV tau ntawv pov thawj 5083 txhuas daim hlau tsim los ua kom tau raws li qhov xav tau nruj ntawm kev faib cov koom haum thiab cov neeg ua dej hiav txwv thoob ntiaj teb.
Hauv phau ntawv qhia dav dav no, peb yuav nthuav dav cov kev qhia tshwj xeeb, cov txiaj ntsig ua haujlwm, thiab cov ntawv pov thawj yuav tsum tau ua ntawm 5083 H116 marine aluminium phaj thiab vim li cas nws yog qhov kev xaiv kawg rau koj qhov kev tsim khoom tom ntej.
Dab tsi yog5083 H116 Marine Aluminium Phaj?
5083 aluminium alloy phaj belongs rau 5000 series (Aluminium-Magnesium alloys). Nws muaj cov ntsiab lus magnesium siab (4.0% -4.9%), uas muab lub zog tshwj xeeb yam tsis tas yuav tsum tau kho cua sov.
Txawm li cas los xij, siab -magnesium alloys tuaj yeem raug cuam tshuam rau intergranular corrosion thiab exfoliation corrosion thaum raug dej hiav txwv hnyav dhau sijhawm. Qhov no yog qhov uas 5083 H116 npau taws dhau los ua qhov tseem ceeb.
Tsis zoo li tus qauv tempers, 5083 H116 txhuas ntawv hlau yog ib qho tshwj xeeb marine temper. Nws qhia tau hais tias 5083 H116 marine aluminium ntawv tau raug strain-hardened thiab meticulously stabilized los tswj nws sab hauv microstructure. Qhov kev ua haujlwm tshwj xeeb no ua kom lub phaj hla dhau qhov hnyav ASTM G66 (exfoliation corrosion) kuaj. Thaum koj yuav 5083 H116 txhuas phaj, koj tab tom yuav tau lav ntev -lub sij hawm tiv thaiv kev txhoj puab heev ntawm dej hiav txwv.
Kho cov tshuaj muaj pes tsawg leeg rau Marine Qib 5083
Rau cov phaj txhuas kom muaj sia nyob tau ntau xyoo hauv dej hiav txwv, nws cov tshuaj purity yuav tsum tau tswj nruj me ntsis. Pheej yig, tsis muaj ntawv pov thawj txhuas feem ntau muaj cov hlau lossis tooj liab siab, uas yuav ua raws li cathodic chaw hauv dej hiav txwv, ua rau pitting ceev ceev.
Raws li tus neeg muag khoom ntseeg siab, GNEE nruj me ntsis ua raws li EN 573 thiab ASTM B928 tus qauv rau peb.Marine qib aluminium 5083 H116.
