Kugwiritsa ntchito machubu osapanga dzimbiri mumafuta amafuta ndi mafakitale a petrochemical

Chitsulo chosapanga dzimbiri molingana ndi kapangidwe ka mankhwala amatha kugawidwa mu Cr chitsulo chosapanga dzimbiri, CR-Ni chitsulo chosapanga dzimbiri, CR-Ni-Mo chitsulo chosapanga dzimbiri, malinga ndi gawo la ntchito zitha kugawidwa muzitsulo zosapanga dzimbiri zamankhwala, chitsulo chosapanga dzimbiri cha mumlengalenga, chitsulo chosapanga dzimbiri, anti- makutidwe ndi okosijeni zosapanga dzimbiri, Cl - dzimbiri kugonjetsedwa ndi chitsulo chosapanga dzimbiri.Koma gulu lomwe limagwiritsidwa ntchito kwambiri ndilolingana ndi kapangidwe kachitsulo kagawo, nthawi zambiri amatha kugawidwa kukhala chitsulo chosapanga dzimbiri, austenitic chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri cha martensitic, chitsulo chosapanga dzimbiri cha duplex ndi mpweya wowumitsa chitsulo chosapanga dzimbiri.Mu petroleum ndi petrochemical applications, austenitic stainless steel, ferritic zosapanga dzimbiri ndi duplex zosapanga dzimbiri zimapanga gawo lalikulu.
Chitsulo chosapanga dzimbiri cha Ferritic Cr chili pakati pa 13% -30%, C zomwe zili ndi C nthawi zambiri zimakhala zosakwana 0.25%, kudzera pakuwotcha kapena kukalamba, carbide mumphepo yam'malire ambewu ya ferritic, kuti ikwaniritse kukana dzimbiri.Nthawi zambiri, kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri ndi kotsika kuposa chitsulo chosapanga dzimbiri cha austenitic ndi duplex chitsulo, koma ndipamwamba kuposa chitsulo chosapanga dzimbiri cha martensitic.Koma chifukwa cha mtengo wake wochepa wopangira poyerekeza ndi zitsulo zina zosapanga dzimbiri, motero, muzamankhwala ndi petrochemical ntchito, zosagwirizana ndi dzimbiri komanso zofunikira zamphamvu sizokwera kwambiri pakugwiritsa ntchito.Monga mafuta a sulfure, hydrogen sulfide, kutentha kwa nitric acid, carbonic acid, mowa wa hydrogen ammonia wa amayi, kupanga urea wa ammonia wotentha kwambiri, mowa wa urea ndi vinylon kupanga vinyl acetate, acrylonitrile ndi malo ena amagwiritsidwa ntchito kwambiri.

Zomwe Cr zili muzitsulo zosapanga dzimbiri za martensitic zili pakati pa 13% -17%, ndipo C zili pamwamba, pakati pa 0.1% ndi 0.7%.Ili ndi mphamvu zambiri, kuuma komanso kukana kuvala, koma kukana kwa dzimbiri ndikotsika.Amagwiritsidwa ntchito kwambiri pamafuta a petroleum ndi petrochemical m'malo omwe sing'anga zowononga sizolimba, monga kulimba kwambiri komanso zida zonyamula katundu, monga masamba opangira nthunzi, mabawuti ndi magawo ena okhudzana ndi zigawo.

Zomwe zili mu Cr muzitsulo zosapanga dzimbiri za austenitic zili pakati pa 17% -20%, zomwe zili mu Ni zili pakati pa 8% -16%, ndipo zomwe zili mu C nthawi zambiri zimakhala zochepa kuposa 0.12%.Mapangidwe a austenitic amatha kupezeka kutentha kutentha powonjezera Ni kukulitsa malo osinthika a austenitic.Austenitic zosapanga dzimbiri zosapanga dzimbiri kukana, plasticity, kulimba, processing ntchito, kuwotcherera ntchito, otsika kutentha ntchito poyerekeza ndi zitsulo zosapanga dzimbiri ndi zabwino kwambiri, kotero ntchito yake m'madera osiyanasiyana ndi yaikulu kwambiri, ntchito yake pafupifupi 70% ya ndalama zonse. zitsulo zonse zosapanga dzimbiri.M'munda wa petroleum ndi petrochemical, wamphamvu zikuwononga sing'anga ndi otsika kutentha sing'anga, ubwino wa austenitic zosapanga dzimbiri zitsulo ndi zazikulu, monga mkulu dzimbiri kukana, makamaka chigawo chamkati kukana intergranular dzimbiri chilengedwe, monga kutentha exchanger / payipi zovekera, cryogenic Liquefied Natural gas (LNG) mapaipi, monga urea, sulfure ammonia kupanga chidebe, flue gasi fumbi kuchotsa ndi desulfurization chipangizo.

Chitsulo chosapanga dzimbiri cha Duplex chimapangidwa pamaziko a chitsulo chosapanga dzimbiri cha gawo limodzi, zomwe zili ndi Ni nthawi zambiri zimakhala pafupifupi theka la chitsulo chosapanga dzimbiri cha austenitic Ni okhutira, kuchepetsa mtengo wa aloyi.Chitsulo chosapanga dzimbiri cha Austenitic chimakhala ndi kukana kwa dzimbiri komanso magwiridwe antchito apamwamba kwambiri, chimathetsa kufooka kwa chitsulo chosapanga dzimbiri cha ferritic ndi martensitic, kulimba kwachitsulo chosapanga dzimbiri cha austenitic komanso kukana kuvala.M'munda wa petroleum ndi petrochemical, zimagwiritsa ntchito madzi a m'nyanja kusamva dzimbiri nsanja mafuta m'mphepete mwa nyanja, zigawo acidic ndi zipangizo, makamaka potting dzimbiri kugonjetsedwa zigawo zikuluzikulu.

Mpweya wolimbitsa chitsulo chosapanga dzimbiri makamaka kudzera pamakina olimbikitsa mvula kuti ugwire ntchito mwamphamvu kwambiri, umaperekanso kukana kwa dzimbiri, motero umagwiritsidwa ntchito pang'ono m'malo owononga, omwe amagwiritsidwa ntchito kwambiri m'migodi yamakina a petrochemical ndi mafakitale ena.

Kugwiritsa ntchito machubu osapanga dzimbiri mumafuta amafuta ndi mafakitale a petrochemical

Makampani a petroleum ndi petrochemical ndiye gawo lalikulu lazachuma cha dziko, lomwe limagwira ntchito yofunika kwambiri pazachuma cha dziko.M'zaka 20 zapitazi, chitoliro zitsulo zosapanga dzimbiri ngakhale chitoliro chosasokoneka kapena chitoliro chowotcherera pamlingo wopanga zida zasintha kwambiri.Chitoliro chachitsulo chosapanga dzimbiri chopangidwa ndi opanga ena apakhomo chafika pamlingo womwe ungathe m'malo mwa zinthu zomwe zimatumizidwa kunja, pozindikira kutanthauzira kwa chitoliro chachitsulo.

M'makampani amafuta ndi petrochemical, chitoliro chachitsulo chosapanga dzimbiri chimagwiritsidwa ntchito kwambiri pamapaipi otumizira, kuphatikiza chubu cha ng'anjo yothamanga kwambiri, mapaipi, chitoliro chophwanyira mafuta, chitoliro chotumizira madzimadzi, chubu chosinthira kutentha ndi zina zotero.Chitsulo chosapanga dzimbiri chimafunika kuti chizigwira bwino ntchito yonyowa ndi asidi.
