Kev cuam tshuam ntawm Gas thiab impurity Contamination ntawm Vuam Kev Ua Haujlwm ntawm Titanium Kub Exchanger

Titanium heat exchangers tsis yooj yim rau poob hlau ions, yog li lawv tuaj yeem siv tag nrho ntawm qhov tsis sib nqus no thiab siv los ua cov khoom siv hluav taws xob rau kev siv tshuaj thiab khoom noj. Vim muaj zog corrosion kuj ntawm titanium, lub neej kev pab cuam ntawm lub titanium tshav kub exchanger yog ntev, thiab cov txij nkawm tus nqi kuj tsawg thaum siv. Tsis tas li ntawd, vim nws qhov me me thiab qhov loj ntawm cov cua sov hloov pauv, cov peev txheej thiab cov nqi khiav lag luam ntawm cov cuab yeej muaj feem xyuam (xws li cov twj tso kua mis) kuj tuaj yeem txo raws li.
Cov cuab yeej siv vuam siv nyob rau hauv titanium tshav kub exchanger paub qhov vuam thiab tsim cov hlau nyias-walled titanium raj thiab cov ntawv raj, uas tsis yog tsuas yog txhim kho kev tsim khoom, txo cov nqi ua haujlwm, tab sis kuj ua rau lub neej ntev thiab kev tsim khoom ntawm cov khoom siv, yog li nws muaj qhov tseem ceeb ntawm daim ntawv thov kev lag luam.
Nyob rau hauv chav tsev kub, titanium thiab titanium alloys kuj ruaj khov. Txawm li cas los xij, thaum lub sij hawm vuam txheej txheem, cov kua tee dej thiab molten pas dej ua ke hlau muaj cov nyhuv ntawm absorbing hydrogen, oxygen thiab nitrogen, thiab nyob rau hauv cov khoom, cov gases twb interacted nrog lawv. Raws li qhov kub thiab txias, lub peev xwm ntawm titanium thiab titanium alloys nqus hydrogen, oxygen thiab nitrogen kuj nce ntxiv. Nws pib nqus hydrogen ntawm li 250 degree, nqus oxygen los ntawm 400 degree, thiab nqus nitrogen los ntawm 600 degree. Tom qab cov roj no tau nqus, nws yuav ncaj qha ua rau embrittlement ntawm cov pob qij txha welded, uas yog ib qho tseem ceeb cuam tshuam rau cov vuam zoo ntawm titanium tshav kub exchangers.
