Corrosion tsis kam tsom xam ntawm nuclear zog tsis haum 690 Evaporator Thaum tshav kub kub hloov raj

Tib neeg siv lub zog nuclear los tsim hluav taws xob rau cov txiaj ntsig ntawm noob neej thiab ntsib tib neeg xav tau lub zog; Txawm li cas los xij, nuclear yog rab ntaj ob leeg, thiab kev nyab xeeb thiab kev puas tsuaj ntawm lub zog hluav taws xob yog qhov ua tau zoo rau tib neeg txoj kev nyab xeeb hauv kev ua haujlwm nyab xeeb ntawm kev ua haujlwm loj ntawm nuclear tsob nroj . nyob rau hauv thiaj li yuav txuas ntxiv ua kom muaj kev nyab xeeb thiab kev ua kom zoo ntawm cov khoom cua sov

Tom qab ntau dua 50 xyoo ntawm kev loj hlob, cov ntaub ntawv rau lub zog nuclear everfe nrog nws cov khoom siv raj tau hloov pauv thiab ua kom muaj kev ntxhov siab kev tsim khoom siv hluav taws xob nuclear fais fab hloov cov tub rog los ntawm peb lub tebchaws. Thev naus laus zis yog tsis pub lwm tus paub, yog cov khoom siv hluav taws xob ntawm kev txhim kho kev lag luam nuclear qauv .

Nuclear zog nroj tsuag feem ntau yog muaj ntawm ob lub zog hluav taws xob thiab theem nrab ntawm cov pa hluav taws xob thiab cov cua sov} los ntawm nuclear kev tawm dag zog nyob rau hauv lub reactor yog nqa mus rau evaporator, thiab hais tias nws rhawv hluav taws xob lub zog los ua haujlwm hauv ob qho kev sib txawv tshaj tawm, lawv Siv cov mob kuj sib txawv, yog li cov cai rau lawv yog qhov nruj me ntsis ntawm cov raj hluav taws xob ua haujlwm cuam tshuam rau cov khoom siv cua sov .

Cov ntaub ntawv ntawm Evaporator Thaum tshav kub kub hloov cov leeg muaj yeej los ntawm peb theem hauv qab no:

Thawj theem tau nyob rau xyoo 1950 thiab 1960s, lub zog thaum ntxov hloov lub zog {} Txawm li cas los xij, cov hlau no tsis zoo rau Chloride ion corrosion, thiab muaj ntau ntawm cov hlau yeeb nkab sib tsoo tau tshwm sim .

Qhov theem ob tau nyob rau xyoo 1970 . raws li cov kev paub ntawm petrochemical-resistant incomplection 600 nickel-based alloy kav dej tau xaiv; Inconel 600 Nickel-based alloy raug kev txom nyem centic kev puas tsuaj los ntawm {} Cov ntsiab lus niroy 800 alloy yog qhov qis dua li ntawm Incoloy 600 Nickel-based alloy, yog li a Tus nqi npib tsawg tau txais kev cawmdim {1800 alloy yog qhov ntau dua li ntawm cov kev sib tsoo ntawm cov khoom siv thib peb uas tuaj yeem siv rau cov tshuaj tiv thaiv dej evaporators tom qab {{}}} stainless hlau thiab inconel 600 npib tsib xee-based alloy.

Theem peb yog tom qab 1980s. Nyob rau hauv cov teeb meem kev ntxhov siab tsis kam rau corrosion nrog ntau yam kev tshaj tawm xov xwm thiab kev kub siab atmospheres . Cov alloy muaj cov yam ntxwv zoo dua qub, ua rau muaj cov khoom siv ntshiab thiab cov khoom tseem ceeb rau nuclear evaporator tso dej Reactors . txij thaum 1990s, muaj kev txhim kho corrosion-resistant inconel 690 kav tau siv hauv kev tsim kho engine ....

Txij li thaum kev txhim kho ntawm lub zog nuclear hauv kuv lub teb chaws, nuclear ever nrog cov neeg siv hluav taws xob tau siv sib txawv,}} Tsim los ntawm nws tus kheej, tau muaj kev sib cuag ntau dua nrog Tebchaws Europe thiab siv lub zog ntawm cov neeg German tau siv cov hwj chim uas tsis ntev los no

Tam sim no, yuav luag txhua evaporators ntawm tshiab tsim thiab siv hluav taws xob nucreally uas xub pib hloov pipes {.

2.}}}} Cov Khoom Siv Tshuaj Muaj Zog Ntawm Inonel 690 Cov Khoom Siv

Inonel 690 alloy (nominal composition Ni-30Cr-9Fe) is an austenitic nickel-based corrosion-resistant alloy with a C content of no more than 0.03% and a Cr content of about 30%. The main difference between the chemical composition of Inconel 690 and Inconel 600 alloys is that Inconel 690 increases the Cr content (28%-30%) and correspondingly reduces the Ni content (>58%) {{.} omoy} {{{{{} {} {}
