Nei Stainless Steel U-Tube Heat Exchanger neFlange Connections Zvichikonzera Kuora

Zvishandiso zvinopisa zvinhu zvakakosha mumaindasitiri akawanda, kubva kumafekitori emagetsi nenzvimbo dzemafuta kusvika pakugadzira chikafu nekugadzira mishonga. Pakati pemagadzirirwo akasiyana-siyana, zvishandiso zvinopisa zveU-tube zvinoshandiswa zvakanyanya nekuda kwekugona kwazvo kubata kuwedzera kwekupisa, dhizaini diki, uye kutamisa kupisa zvinobudirira. Zvisinei, dambudziko rimwe rinowanzo sangana nevashandisi ndere ngura yemachubhu eU-tube heat exchanger esimbi isina tsvina panzvimbo yekubatanidza flange.

Chinyorwa chino chinoongorora kuti sei matambudziko aya ekuora achiitika, nzira dzinoshandiswa, uye kuti mainjiniya nevanoshandisa mafekitori vanogona sei kuderedza njodzi. Nekunzwisisa zvikonzero, zvinova nyore kusarudza zvinhu zvakakodzera, magadzirirwo, uye nzira dzekugadzirisa kuti uwedzere hupenyu hwebasa remuchina.

Maumbirwo eU-Tube Heat Exchanger

Chinochinja kupisa cheU-tube chinosanganisira:

  • Chikwama cheChubhu:Machubhu esimbi isina ngura akakombamiswa kuita chimiro cheU kuti agadzire diki.

  • Tube Sheet uye Flanges:Machubhu anoiswa muchubhu uye anovharwa nemaflanges kuti abatanidzwe nemapombi ekunze.

  • Rutivi rweShell:Goko guru rakakomberedza chubhu, uko mvura imwe chete inoyerera.

  • Rutivi rweChubhu:Mvura inoyerera mukati memachubhu eU esimbi isina ngura.

Nzvimbo yeflange inzvimbo yakakosha pakudzivirira kubuda kwemvura, kuvhara, uye kuramba ngura kunofanirwa kutarisirwa nokungwarira.

Nei Kuora Kuchiitika paFlange Connections

1. Kuora kwemupata

Kubatana kweflange kunoita kuti pave nemikana yakamanikana pakati pemagasket, mabhaudhi, uye pamusoro peflange. Mikana iyi inowanzobata mvura isingamire, zvichiita kuti huwandu hwakasiyana hweokisijeni huwedzere. Izvi zvinoita kuti ngura ikurumidze kuitika munzvimbo imwe chete, kunyangwe musimbi isingatsvi.

2. Kuora kweGalvanic

Kana simbi dzakasiyana dzichishandiswa mukubatanidza flange, dzakadai se carbon steel flanges pamwe chete ne stainless steel U-tubes, galvanic corrosion inogona kuitika. Musiyano we electrochemical potential pakati pesimbi unotungamira mukukurumidzira corrosion panosangana flange.

3. Kupwanya Kunokonzerwa neChloride

Simbi dzisina ngura dzakadai se304 kana 316 dzinogona kukanganiswa nekuiswa kwechloride kana dzikaiswa mumvura yegungwa, munyu, kana mvura ine chloride. Nzvimbo yeflange, sezvo yakaoma kuchenesa nekuongorora, inova nzvimbo inonyanya kurwiswa nechloride.

4. Kuora kweGasket

Zvinhu zvisina kukwana zvegasket zvinogona kuora kana paine tembiricha yakakwira kana makemikari ane simba, zvichisiya mipata yekuti mvura inoparadza ipinde yorwisa pamusoro pesimbi isina ngura.

5. Kutsemuka Kweganda Nekuora (SCC)

Nzvimbo dzakaita seflange dzinosangana nekumanikidzwa kwakanyanya nekuda kwekusimba kwemabhaudhi uye kuwedzera kupisa. Kana zvikasanganiswa nemachloride kana kupisa kwakanyanya, mamiriro aya ekumanikidzwa anogona kukonzera kutsemuka kwesimbi isingatsvedzeri.

6. Kuwanda Kwezvinhu Zvinosvibisa

Chinomonera flange chinowanzo unganidza tsvina, madhaka, uye masara emakemikari. Kuwanda kwetsvina iyi munharaunda kunowedzera kukurumidza ngura kana tichienzanisa nezvimwe zvikamu zvemuchina wekuchinjisa.

Magiredhi eSimbi Isina Stainless muU-Tube Heat Exchangers

  • 304 Simbi Isina Kushanda:Kuramba ngura kwakajairika, asi kuramba machloride kwakaderera.

  • 316 / 316L Simbi Isina Kushanda:Kuramba kuri nani ku chloride pitting, inoshandiswa zvakanyanya mumaindasitiri egungwa nemakemikari.

  • 321 Simbi Isina Zvisimbiso:Yakasimba netitanium, yakanaka pakushandiswa pakupisa kwakanyanya.

  • Simbi Dzisina Kusimba Dziviri (2205, 2507):Kudzivirira kwakanyanya kupwanya ngura nekuoma uye simba rayo guru.

  • Simbi Isina Kusimba ye904L:Kupikisa zvakanyanya maasidhi nemakloridhi, anowanzo shandiswa munzvimbo dzine makemikari akaomarara.

Pasinei nemabhenefiti azvo, kunyange magiredhi aya anogona kusangana nengura munzvimbo kana dhizaini yeflange, kuvhara, uye kugadzirisa zvisina kukwana.

Mashandisirwo Emaindasitiri Panoitika Dambudziko Rengura

  1. Kugadzira Simba:Zvidziyo zvemvura zvinofambisa mvura mubhoyira uye zvinopa mvura inodziya zvinowanzosangana nengura yeflange nekuda kwekushanduka-shanduka kwemakemikari emvura.

  2. Zvirimwa zvePetrokemikari:Mvura ine chloride yakawanda inorwisa nzvimbo dzegasket neflanges.

  3. Zvirimwa zvekubvisa munyu:Kusviba mumvura yegungwa kunokurumidza kudonha kwemakomba uye ngura pamapfundo.

  4. Chikafu Nechinwiwa:Zvisaririra panzvimbo dzakaita seflange zvinogona kukonzera ngura inokonzerwa nehutachiona kana zvikasacheneswa zvakanaka.

  5. Indasitiri yeMishonga:Masisitimu emvura akachena kwazvo anoda kuvharwa kwakakwana, asi kudonha kudiki kunokonzera ngura mumipata.

Migumisiro yeKuora paFlange Connections

  • Kushanda zvishoma kwekuvhara, zvichikonzera kubuda kwemvura.

  • Kurasikirwa nekushanda zvakanaka kwemuchina wekupisa nekuda kwekukuvara kwechubhu.

  • Mari yekuchengetedza yakawedzera uye nguva yekuzorora isina kurongwa.

  • Njodzi dzekuchengetedza dzinobva pakubuda kwemvura kana paine kumanikidzwa kwakanyanya.

  • Kupfupisa hupenyu hwemidziyo, zvichida kuti ishandiswezve nekukurumidza.

Matanho ekudzivirira

1. Kusarudzwa Kwezvinhu

Sarudza simbi isina ngura ine nhamba yakaenzana yekudzivirira makomba (PREN) senge simbi dzisina ngura mbiri kana 904L dzenzvimbo dzine chloride yakawanda.

2. Dhizaini yeFlange neGasket

  • Shandisa zvinhu zvegasket zvinoenderana nazvo zvisingakuvadzi mvura inobuda.

  • Iva nechokwadi chekuti bhaudhi rakasimba zvakaenzana kudzivirira kushushikana.

  • Funga nezvemagasket emuchindwe anotenderera kana magasket ePTFE emakemikari anopisa.

3. Kurapa Kwepamusoro uye Kuputira

Kuisa machira ekudzivirira kana kutenderedza pamusoro peflange kunogona kuwedzera kusimba kwengura.

4. Dziviriro yeCathodic

Mune mamwe mashandisirwo, dziviriro ye cathodic inogona kushandiswa kuderedza ngura ye galvanic.

5. Kugadzirisa Nekuongorora Kwakakodzera

  • Kuongororwa nguva dzose kwenzvimbo dzeflange panguva yekuvharwa.

  • Kuchenesa zvinhu zvakasara uye zvakasara kuti pasave nekuwanda kwemarudzi anoparadza.

  • Kutsiva magaskets panguva dzakarongwa.

6. Maitiro Akavandudzwa Ekugadzira

  • Dzivisa kusvibiswa panguva yekunamira nekugadzira.

  • Iva nechokwadi chekuti nzvimbo dzakatsetseka pamajoini dzinoita kuti pasave nekutsemuka.

  • Shandisa torque inodzorwa pamabhoti kudzivirira kushushikana kwakanyanya.

Muenzaniso weChidzidzo Chenyaya

Mufekitori yekubvisa munyu, ma "heat exchangers" esimbi isina tsvina ye316L U-tube akabatanidzwa ne "carbon steel flanges". Mukati memakore maviri, ngura huru yakaonekwa pa "flanges" dzakabatana nekuda kwe "galvanic effects" uye kusvibiswa nemvura yegungwa. Mushure mekugadziriswa kuita "duplex stainless steel flanges" uye "PTFE gaskets", fekitori iyi yakashanda kwemakore anopfuura gumi pasina matambudziko makuru engura.

Mafambiro Emangwana Muzvinhu Zvinochinja-chinja Kupisa

Sezvo maindasitiri achida kuvimbika kwakanyanya uye hupenyu hurefu hwebasa, kushandiswa kwesimbi dzisina ngura dzemhando yepamusoro, ma super austenitic alloys, uye ma nickel-based alloys kuchawedzera. Kuvandudzwa kwezvinhu zvegasket uye matekinoroji ekuvhara flange kuchawedzera kuderedza njodzi dzengura mumashandisirwo akakosha.

Sei Uchifanira Kutsvaga Machubhu eSimbi Isina Kugadzika uye Zvishandiso kubva kuSakysteel

Pakugadzira nekushandisa ma "heat exchangers", kusarudza mutengesi akakodzera kwakakosha sekusarudza chinhu chakakodzera.sakysteeline mhando dzakasiyana-siyana dzemachubhu esimbi isina ngura, maflange, uye zvigadziko zvinoenderana neASTM, ASME, uye EN standards. Iine hutongi hwakasimba hwemhando, nzvimbo dzekuongorora dzepamusoro, uye kurongedza kwakagadzirira kutumira kunze kwenyika,sakysteelinovimbisa kuvimbika uye kushanda kwenguva refu kwezvishandiso zvemaindasitiri zvinochinja kupisa pasi rose.

Mhedziso

Kuora pakubatanidza flange yeU-tube heat exchangers dzesimbi isina ngura idambudziko rakajairika asi rinogona kudzivirirwa. Zvinhu zvakaita sekuora kwemupata, galvanic corrosion, chloride attack, uye gasket degradation zvese zvinobatsira mukukuvara kwenzvimbo. Nekusarudza giredhi resimbi isina ngura rakakodzera, kushandisa zvinhu zvegasket zvakakodzera, kushandisa nzira dzekudzivirira, uye kuita ongororo nguva dzose, maindasitiri anogona kuwedzera hupenyu hwebasa reheat exchangers dzavo.

Kunzwisisa kuti sei nzvimbo idzi dziri panjodzi kunobvumira mainjiniya kushandisa nzira dziri nani dzekugadzira nekugadzirisa, vachiona kuti mashandiro akachengeteka, anoshanda zvakanaka, uye asingadhuri mumaindasitiri akasiyana-siyana.
