Stainless Simbi Yakaputirwa Tubes Chemical Composition

Hunhu uye certification inotaridza kusarudzwa kwezvinhu zvemasisitimu senge plate heat exchangers (PHEs), mapaipi nemapombi muindasitiri yemafuta negesi.Matekinoroji ehunyanzvi anovimbisa kuti zvinhu zvinopa kuenderera kwemaitiro pamusoro pehupenyu hurefu uku uchiona mhando, chengetedzo uye kuchengetedzwa kwezvakatipoteredza.Ichi ndicho chikonzero vazhinji vanoshanda vachisanganisira nickel alloys seAlloy 625 mune yavo yakatarwa uye zviyero.
Parizvino, zvakadaro, mainjiniya anomanikidzwa kudzikamisa mari yemari, uye nickel alloys anodhura uye ari panjodzi yekushanduka kwemitengo.Izvi zvakajekeswa muna Kurume 2022 apo mitengo ye nickel yakawedzera zvakapetwa muvhiki nekuda kwekutengesa kwemusika, kuita misoro.Nepo mitengo yakakwira ichireva kuti nickel alloys inodhura kushandisa, kusagadzikana uku kunogadzira matambudziko ekutungamira kune mainjiniya ekugadzira sezvo shanduko yemitengo yakangoerekana yakonzera pundutso.
Nekuda kweizvozvo, vazhinji vanogadzira mainjiniya vava kuda kutsiva Alloy 625 nedzimwe nzira kunyangwe vachiziva kuti vanogona kuvimba nemhando yayo.Chinokosha ndechekuziva iyo alloy yakakodzera ine chiyero chakakodzera chekudzivirirwa kwemaitiro emvura yegungwa uye kupa alloy inoenderana nema mechanical properties.
Chinhu chimwe chakakodzera EN 1.4652, inozivikanwawo seOutokumpu's Ultra 654 SMO.Inoonekwa seyakanyanya kuodza isingagone simbi pasi rose.
Nickel Alloy 625 ine kanenge 58% nickel, nepo Ultra 654 ine 22%.Ose ane anenge akafanana chromium uye molybdenum zvemukati.Panguva imwecheteyo, Ultra 654 SMO inewo shoma shoma ye nitrogen, manganese uye mhangura, 625 alloy ine niobium uye titanium, uye mutengo wayo wakakwirira zvikuru kupfuura we nickel.
Panguva imwecheteyo, inomiririra kuvandudzwa kwakakosha pamusoro pe316L simbi isina tsvina, iyo inowanzoonekwa senzvimbo yekutanga yekushanda kwepamusoro simbi isina tsvina.
Panyaya yekushanda, iyo alloy ine yakanaka kwazvo kupikisa kune general corrosion, yakanyanya kupikisa kugomba uye crevice corrosion, uye kuramba kwakanaka kushushikana nekupwanya kwekupwanya.Nekudaro, kana zvasvika kune masisitimu emvura yegungwa, Stainless simbi alloy ine mupendero pamusoro peiyo alloy 625 nekuda kweiyo yepamusoro chloride kuramba.
Mvura yegungwa inoparadza zvakanyanya nekuda kwemunyu we18,000 kusvika ku30,000 zvikamu pamiriyoni yemaioni echloride.Chlorides inopa njodzi yekuora kwemakemikari kune akawanda magiredhi esimbi.Nekudaro, zvipenyu zviri mumvura yegungwa zvinogona zvakare kuumba biofilms inokonzera electrochemical kuita uye kukanganisa kuita.
Iine yakaderera nickel uye molybdenum zvirimo, iyo Ultra 654 SMO alloy musanganiswa inoburitsa yakakosha mari yekuchengetedza pamusoro pechinyakare yakakwira yakatarwa 625 alloy uchichengeta mwero wakafanana wekuita.Izvi zvinowanzochengetedza 30-40% yemutengo.
Uye zvakare, nekudzikisira zvirimo zvakakosha alloying zvinhu, simbi isina tsvina zvakare inoderedza njodzi yekushanduka-shanduka mumusika nickel.Nekuda kweizvozvo, vagadziri vanogona kuve vane chivimbo mukururama kwemazano avo ekugadzira uye makotesheni.
Iyo mechanic zvimiro zvezvinhu chimwe chinhu chakakosha kune mainjiniya.Mapombi, zvinochinjisa kupisa, uye mamwe masisitimu anofanirwa kushingirira zvakanyanya, tembiricha inoshanduka, uye kazhinji kacho kuzunguzika kana kuvhunduka.Iyo Ultra 654 SMO yakamira zvakanaka munzvimbo ino.Iine simba guru rakafanana nealloy 625 uye yakakwirira zvakanyanya kudarika mamwe masimbi asina tsvina.
Panguva imwecheteyo, vagadziri vanoda zvinhu zvinogadzirwa uye zvinogoneka zvinopa kugadzirwa nekukurumidza uye zviri nyore kuwanikwa mune inodiwa chigadzirwa fomu.
Panyaya iyi, alloy iyi isarudzo yakanaka nekuti inochengetedza kuumbwa kwakanaka uye kurebesa kwakanaka kwechinyakare austenitic mamakisi, zvichiita kuti ive yakanaka kugadzira mahwendefa akasimba, asina kuremerwa ekupisa.
Iyo zvakare ine yakanaka weldability uye inowanikwa nenzira dzakasiyana siyana kusanganisira makoiri nemashiti anosvika 1000mm yakafara uye 0.5 kusvika 3mm kana 4 kusvika 6mm gobvu.
Imwe mari inobatsira ndeyekuti alloy ine yakaderera density pane alloy 625 (8.0 vs. 8.5 kg/dm3).Kunyange zvazvo musiyano uyu ungasaratidzika kuva wakakosha, unoderedza tonnage ne6%, izvo zvinogona kukuchengetedza mari yakawanda kana uchitenga zvakawanda zvezvirongwa zvakadai semapaipi ehutu.
Pahwaro uhwu, density yakaderera inoreva kuti chimiro chakapedzwa chichava chakareruka, zvichiita kuti zvive nyore kuita, kusimudza uye kuisa.Izvi zvinonyanya kukosha mu subsea uye offshore application uko zvinorema masisitimu anonetsa kubata.
Tichifunga nezvese maficha uye mabhenefiti eUltra 654 SMO - yakakwira corrosion kuramba uye simba remagetsi, kugadzikana kwemutengo uye kurongeka kwakaringana - zviri pachena zvine mukana wekuva imwe nzira inokwikwidza kune nickel alloys.
