Puas yog Inconel lub siab kub alloy?
Cov hlau alloys yuav tsum muaj peev xwm tiv taus ntau qhov chaw huab cua, thiab kev ua haujlwm kub tuaj yeem yog qhov tseem ceeb hauv kev xaiv cov khoom. Hmoov zoo, muaj ntau INCONEL alloys uas tuaj yeem ua txoj haujlwm
Thaum muaj ntau yam los xav txog thaum xaiv cov khoom siv rau ib qhov project, tshwj xeeb tshaj yog lub zog thiab corrosion kuj, qhov kub ntawm ib puag ncig uas lawv yuav ua haujlwm yog qhov tseem ceeb. Cov thawj tswj xyuas qhov project yuav tsum tuaj yeem saib txhua yam khoom siv thiab nrhiav qhov uas muab qhov kev ua tau zoo tshaj plaws rau tus kheej ib puag ncig.
Xaiv txoj cai alloy rau kev siv kub kub yog ib txoj kev nyuaj thiab nyuaj. Deformation thiab cracking yuav tshwm sim vim thermal expansion los yog contraction thiab nce nrog kub. Koj kuj yuav tsum xav txog seb ib puag ncig nws yuav siv rau hauv yuav txias dua thaum tsis ua haujlwm, thiab seb qhov no puas tuaj yeem ua kom paub txog corrosion ntawm qhov kub thiab txias.
Corrosion hom
Qhov kub thiab txias ib puag ncig ua rau cov khoom muaj kev pheej hmoo rau qee hom kev xeb. Ib qho ntawm cov no yog oxidation, qhov twg hlau hnov mob nrog huab cua los tsim oxides, yog li oxidation-resistant alloys feem ntau xav tau.
Lub xub ntiag ntawm sulfur gases (xws li hauv petrochemical processing) tuaj yeem ua rau cov hlau puas tsuaj, tshwj xeeb tshaj yog thaum kub kub. Carburization (ib qho teeb meem hauv cov chaw kho cua sov lossis cov txheej txheem roj tawg) kuj nce siab dua, thiab cov xwm txheej no, nrog rau cov xwm txheej oxidizing, ua rau cov hlau tsis muaj zog.
Alloys haum rau qhov kub thiab txias feem ntau yog nickel-based thiab muaj cov ntsiab lus chromium siab. Chromium pab tsim cov oxides tiv thaiv nyob rau hauv cov cheeb tsam no los tiv thaiv corrosion. Cov alloys tseem yuav muaj lwm cov ntsiab lus xws li molybdenum thiab hlau uas ua rau muaj kev tiv thaiv corrosion zoo thiab lub zog siab.
Inconel
GNEE khaws cov kev xaiv dav dav ntawm INCONEL alloys uas zoo tagnrho rau qhov kub thiab txias thaum tseem muab kev tiv thaiv corrosion zoo heev. Ib qho ntawm cov neeg nyiam tshaj plaws yog INCONEL alloy 625, uas paub txog nws qhov kev tiv thaiv rau ntau hom kev xeb nrog rau nws lub zog thermal qaug zog. Nws muaj qhov kev pabcuam kub txog li 982 degree thiab tiv taus cov teebmeem kub kub xws li oxidation thiab carburization. Vim nws lub zog tsim muaj peev xwm ntawm qhov kub thiab txias, ib qho ntawm nws cov ntawv thov yog nyob rau hauv cov ntsiab lus siab heev reactor.
Lwm cov high-chromium-nickel alloy paub txog nws cov kev pabcuam kub kub zoo yog INCONEL Alloy 690. Cov alloy muaj kev tiv thaiv zoo rau cov kub-kub oxidizing gases thiab tseem tuaj yeem pom cov nqi qis thiab ua rau muaj kev ntxhov siab corrosion cracking nyob rau hauv high-temperature ib puag ncig. dej kub. Qhov no ua rau nws yog qhov kev xaiv nrov rau lub tshuab hluav taws xob cov raj, baffles thiab tubesheets, nrog rau cov khoom siv hluav taws xob tsim hluav taws xob nuclear.
