Vuam txheej txheem siv rauZirconium Tubular Thaum tshav kub kub Exchangers
Vuam ntawm zirconium tubular tshav kub exchangers yuav tsum tau tshwj xeeb txheej txheem los xyuas kom meej kev sib koom ua ke, corrosion kuj thiab txhua yam kev ua tau zoo. Cov txheej txheem vuam tseem ceeb feem ntau siv, nrog rau lawv cov yam ntxwv tseem ceeb thiab daim ntawv thov scenarios, yog cov ncauj lus kom ntxaws raws li hauv qab no.
1.Gas Tungsten Arc Vuam
Qhov no yog cov txheej txheem vuam siv ntau tshaj plaws rau zirconium tubular tshav kub exchangers. Nws siv cov khoom siv tsis yog -tungsten electrode thiab inert gas shielding los tiv thaiv lub pas dej ua ke thiab cua sov- thaj tsam cuam tshuam los ntawm huab cua paug. Cov txheej txheem ua kom muaj kev tswj xyuas cov khoom siv hluav taws xob zoo, txo qis thermal distortion thiab khaws cia cov corrosion kuj ntawm zirconium. Nws yog tshwj xeeb tshaj yog haum rau welding nyias- cov phab ntsa zirconium hlab thiab cov raj ntawv sib txuas, qhov twg siab precision thiab zoo yuav tsum tau.
2. Plasma Arc Vuam
Cov txheej txheem no siv lub siab -kub plasma arc los yaj lub hauv paus hlau, muab lub zog ntau dua li cov roj tungsten arc vuam. Nws muab qhov sib sib zog nqus weld nkag mus thiab nqaim cua sov- cov cheeb tsam cuam tshuam, ua rau nws zoo tagnrho rau cov vuam tuab zirconium cov khoom lossis cov pob qij txha uas yuav tsum tau nkag mus rau tag nrho. Lub zog arc ruaj khov ua kom zoo ib yam weld zoo, thiab cov roj inert shielding system zoo tiv thaiv oxidation ntawm thaj chaw weld, tswj cov khoom siv hauv lub cev.
3.Electron Beam Vuam
Siv nyob rau hauv siab -precision thiab siab- cov kev ua tau zoo, cov txheej txheem no siv cov kab hluav taws xob tsom los ua kom muaj cua sov rau vuam. Nws ua haujlwm nyob rau hauv ib puag ncig lub tshuab nqus tsev, tshem tawm qhov xav tau kev tiv thaiv roj ntxiv thiab zam kom tsis txhob muaj paug hauv huab cua. Electron beam welding ua rau siab - lub zog, qhov tsis xws luag- welds dawb nrog tsawg thermal distortion, haum rau cov pob qij txha tseem ceeb hauv zirconium tshav kub exchangers siv nyob rau hauv hnyav ib puag ncig xws li nuclear zog los yog tshuaj industries.
1. Laser Beam Vuam
Siv lub teeb pom kev zoo laser raws li qhov chaw tshav kub, cov txheej txheem no muaj kev vuam ceev thiab precision. Nws tsim qhov nqaim weld seams thiab me me cua sov- thaj chaw cuam tshuam, txo qhov cuam tshuam rau lub hauv paus hlau cov qauv thiab corrosion kuj. Laser beam welding yog tsim rau nyias- cov phab ntsa zirconium raj thiab cov kev sib koom ua ke, ua kom cov khoom siv hluav taws xob tuaj yeem txhim kho kev ua tau zoo thiab sib xws. Kev tiv thaiv roj kom zoo yog yuav tsum tau tiv thaiv lub pas dej ntawm oxidation thaum lub sijhawm ua haujlwm.
2.Shielded Hlau Arc Vuam
Txawm hais tias tsawg dua siv rau nyias- cov khoom siv phab ntsa, cov txheej txheem no muaj feem xyuam rau cov txheej txheem welding thicker zirconium hauv qee qhov xwm txheej. Nws siv cov flux-coated electrode uas muab ob qho tib si muab tub lim thiab tiv thaiv thaum vuam. Lub flux tsim ib txheej tiv thaiv slag hla lub vuam, tiv thaiv kev sib kis. Kev tswj xyuas nruj ntawm cov vuam tsis yog qhov tseem ceeb kom tsis txhob muaj cua sov ntau dhau, uas tuaj yeem ua rau cov khoom tsis zoo thiab cuam tshuam rau kev sib koom tes.
Hauv cov ntsiab lus, kev xaiv cov txheej txheem vuam rau zirconium tubular tshav kub exchangers nyob ntawm cov khoom thickness, sib koom ua ke, kev ua tau zoo thiab kev tsim khoom. Txhua tus txheej txheem muaj nws qhov tshwj xeeb zoo, thiab nruj me ntsis ua raws li cov txheej txheem thiab kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb los xyuas kom meej qhov kev ntseeg tau thiab kev ua neej ntev ntawm cov welded heat exchangers.
