2. Cov khoom piav qhia
Titanium thiab titanium alloy tubes yog cov yam ntxwv ntawm lub zog tshwj xeeb, zoo heev corrosion kuj, thiab superior kub pauv kev ua tau zoo. Nyob rau hauv xyoo tas los no, lawv tau siv dav hauv kev tsim cov hlab ntsha siab rau chlor-alkali kev lag luam thiab cov khoom siv tshuaj lom neeg kev lag luam, xws li ntau lub nkoj siab nrog rau cov khoom siv hluav taws xob thiab cov condensers. Titanium heat exchangers yog ntau tshaj kaum npaug ntau npaum li stainless hlau tshav kub exchangers, nrog rau cov cuab yeej siv tau ntev dua. Seamless titanium thiab titanium alloy tube nplooj ntawv yog ib qho ntawm cov khoom tseem ceeb hauv cov khoom siv hluav taws xob.
Kev tsim qauv tsim ntawm titanium alloy tube nplooj ntawv yog qhov tseem ceeb rau kev xaiv cov khoom tsim nyog, txuag nqi, txo kev ua haujlwm tsis yooj yim, txo cov nqi tsim khoom, thiab ua kom ntseeg tau kev lag luam. Although titanium remains stable in many media, it undergoes passivation in air or oxygen-containing environments, forming a dense, strongly adherent, and highly inert oxide film on its surface. Cov yeeb yaj kiab no tiv thaiv lub hauv paus titanium matrix los ntawm corrosion los ntawm kev cais nws los ntawm cov neeg ua haujlwm corrosive. Nrog rau lub zog tshwj xeeb, titanium raj ntawm tib phab ntsa tuab hnyav dua li cov hlau tsis muaj steel hlau kub exchanger raj. Thaum lub plhaub - sab nruab nrab muaj qhov nruab nrab - mus rau qis - qhov hluav taws xob siab thiab qhov hluav taws xob yog qhov chaw siab, qhov dej tsis zoo. Raws li qhov tshwm sim, sab nrauv ntawm titanium heat exchanger tubes tseem txuas ntxiv mus rau nruab nrab - mus rau qis -sab siab, ua rau muaj corrosion hnyav. Cov khoom tseem ceeb ntawm qhov nruab nrab hauv titanium seamless raj muaj xws li sodium chloride, urea, thiab poov tshuaj ntsev - xov xwm uas muaj corrosive heev thiab nquag mus scaling thiab clogging lub tshav kub exchanger raj.
Titanium muaj zog corrosion kuj thiab zoo heev tshav kub hloov kev ua tau zoo. Vim nws qhov tsis muaj dej tsis zoo, cov kua tsis tsim cov yeeb yaj kiab txuas ntxiv, tab sis hloov cov ntaub ntawv yooj yim tshem tawm tau yooj yim, yog li txo cov thermal tsis kam. Tsis tas li ntawd, vim tias titanium nto tiv thaiv cov yeeb yaj kiab ntub dej, qhov adhesion ntawm cov khoom siv corrosion yog txwv, uas pab tswj kom muaj cua sov hloov coefficient ntau dua, yog li txhim kho cov hluav taws xob hloov pauv tau zoo. Yog li ntawd, titanium tshav kub exchanger raj yog ib qho kev xaiv zoo tshaj plaws rau titanium tshav kub exchangers.
3. Cov txheej txheem tsim khoom
Kev tsim cov titanium kub exchanger tubes yog ib tug complex thiab meej txheej txheem, feem ntau muab faib ua peb theem: raw khoom npaj, raj fabrication, thiab tshav kub exchanger los ua ke.
Kev tsim cov titanium raj pib nrog daim txhuam cev titanium lossis daim txhuam cev titanium sib xyaw nrog cov ntsiab lus alloying. Electrode npaj thiab lub tshuab nqus tsev melting yog siv los cam khwb cia titanium ingots, uas yog ces ua tiav los ntawm ib tug series ntawm yas deformation kauj ruam mus rau hauv cov ntaub ntawv tubular. Cov txheej txheem ntxaws yog raws li nram no:
Nqus Melting: Daim txhuam cev titanium lossis titanium alloy yog melted nyob rau hauv lub tshuab nqus tsev los tsim titanium ingots, kom ntseeg tau tias cov khoom purity siab.
Forging thiab Billet Preparation: Lub titanium ingot yog forged rau hauv ib lub billet haum rau kev ua tom ntej.
Extrusion/Plug Rolling: Siv extrusion los yog skew - dov cov txheej txheem, lub pob zeb yog tsim los rau hauv lub hollow tubular dawb paug.
Txias Rolling / Kos duab: Cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob
Thaum tshav kub kub Exchanger los ua ke txheej txheem
Sib dhos los ntawm cov txheej txheem titanium raj, cov khoom siv hluav taws xob tso siab rau ob txoj hauv kev txuas:
Vuam txoj kev: Tam sim no cov txheej txheem siv dav tshaj plaws, vuam ua kom nruj sealing nyob rau hauv qhov kub thiab txias. Cov cuab yeej siv vuam siv niaj hnub suav nrog pulsed TIG vuam thiab lub tshuab nqus tsev electron beam vuam, haum rau kev koom nrog titanium raj rau cov ntawv raj lossis lwm yam khoom siv.
Expansion Method: Ib lub raj expander compresses ib feem ntawm lub raj tso rau hauv lub qhov nyob rau hauv lub raj ntawv, ua rau cov yas deformation ntawm lub raj thaum inducing elastic deformation nyob rau hauv lub qhov. Tom qab tshem tawm cov expander, lub raj daim ntawv lub qhov sib cog lus, ruaj ntseg kho lub raj nyob rau hauv qhov chaw thiab ua tiav ib tug sib koom ua ke. Txoj kev no yuav tsum muaj siab precision hauv machining ntawm lub raj ntawv qhov.
