Khoom Taw qhia
Titanium condenser raj tau niaj hnub no hloov tooj liab alloys raws li cov khoom siv nyiam tshaj plaws rau cov dej ntsev -coj condensers. Qhov laj thawj tseem ceeb yog qhov zoo tshaj plaws corrosion kuj ntawm titanium hauv chloride - muaj ib puag ncig. Titanium yog niaj hnub no yuav tsum tau suav hais tias yog cov khoom siv tube rau qhov chaw condensers hauv ntsev lossis dej brackish-cooled condensers hauv chav fais fab nroj tsuag ntawm txhua qhov loj. Kev siv cov titanium kuj nce ntxiv hauv cov nroj tsuag hluav taws xob nrog cov cua txias ntauwd circuits nrog rau hauv cov dej tshiab -cov nroj tsuag txias. Raws li cov tuam ntxhab, peb cog lus tias yuav ua tau raws li tus qauv ntawm ASME SB338, ua raws 100% Eddy tam sim no kuaj, thiab 100% Ultrasonic kuaj. Qhov kev paub ntawm titanium tubed condensers feem ntau yog qhov txaus siab.

Cov dej ntsev los yog dej khib nyiab yog siv los ua dej txias rau 75% ntawm cov titanium condensers. Cov titanium condensers tseem tshuav sib npaug sib npaug ntawm cov cua txias ntauwd circuits thiab ib zaug -los ntawm cov dej txias txias.
Yam ntxwv
Nws muaj cov yam ntxwv ntawm corrosion kuj, siab zog, tsawg ntom, thiab lwm yam, tab sis tsuas yog yuav welded nrog ntshiab titanium los yog ib co titanium alloys thaum vuam, thiab vuam ib puag ncig muaj siab yuav tsum tau. Hauv cov txheej txheem vuam, cov kua dej thiab cov pas dej ua ke muaj lub luag haujlwm muaj zog hauv kev nqus cov hydrogen, oxygen, thiab nitrogen, thiab hauv cov khoom hauv lub xeev, cov roj no tau cuam tshuam 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 250 degree, absorbs oxygen ntawm 400 degree, thiab absorbs nitrogen ntawm 600 degree. Cov gases Tom qab absorbed yuav ncaj qha ua rau embrittlement ntawm welded sib koom, uas yog ib qho tseem ceeb heev cuam tshuam rau lub vuam zoo. Thaum vuam titanium thiab titanium alloys, qhov pores feem ntau ntsib, tab sis cov welds feem ntau tsis tsim cov kab nrib pleb.
Hauv cov ntsiab lus, titanium raj muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, siab zog, thiab tsawg ntom. Lub tshav kub hloov kev ua tau zoo yog yuav luag zoo ib yam li cov tooj liab alloy raj. Vim muaj kev cuam tshuam ntawm cov khoom siv thiab cov txheej txheem vuam, cov condenser tiav yog qhov siab. Xav txog kev lag luam kev cuam tshuam ntawm kev ua haujlwm ntev lub neej thiab tus nqi kho qis, nws muaj kev nyab xeeb dua los xaiv cov titanium condenser raj hauv qee qhov tshwj xeeb kev lag luam lossis cov haujlwm.
