S32205 luj tshib

Corrosion tsis kam ntawm Duplex Log Volius fittings Fittings muab. Piv rau cov qauv txhawb cov qib kev kawm qib siab lossis cov neeg siab. Txawm hais tias cov hlau loj muaj cov kub kub siab xav tsis tau zoo li lwm cov chav kub, sawv tau kub ntawm 300 degrees Celsius rau lub sijhawm luv luv. Thaum embrittlement, duplex stub pob qij txha tsuas yog kho los ntawm kev daws teeb meem tiav kev kho mob.

Werkstoff tsis yog 1.4462 duplex cov yeeb nkab fittings muaj lub siab tiv taus rau intergranular corrosion, tshwj xeeb tshaj yog nyob rau hauv chloride thiab sulphide muaj ib puag ncig. Feem ntau, cov qib steels niaj hnub yuav raug kev cuam tshuam nrog cov mob no, uas nthuav tawm ntau qhov kev ntxhov siab ntsig txog corrosion.

Cov fittings no yog tsim los ntawm cov khoom siv raw zoo tshaj plaws thiab tau txais kev sim zoo thiab tshuaj xyuas raws li cov qauv haujlwm hauv tebchaws thiab thoob ntiaj teb. Cov neeg tsim khoom muaj cov kav dej tag nrho ntawm cov kav dej thiab cov fittings xws li uns uns uns uns unst s32205 45 degrees. Luj tshib, duplex uns s31803 cuplex s31803 lub taub hau weld haum, 2205 khawm weld haum, suplex s32205 haum.

Cov txheej txheem tsis raws S31803 tau raug ua raws li chav kawm duplex vim nws sib xyaw ua ke ntawm kev ua kom zoo nkauj-Ferritic microstructure. Ob lub stuplex stainless hlau ib coloys muaj kev sib npaug ntawm ob qho kev sib npaug

Duplex steel bookweld fittings ua rau zoo dua hauv zos corrosion tsis kam nyob rau hauv kev sib piv rau ob xyoos 316L thiab 317L. Li no cov fullex fittings tau siv nyob rau hauv cov ntawv thov koom nrog ntau cov nroj tsuag muaj tshuaj lom neeg, dej hiav txwv uas nqhis dej, thiab lwm yam.

Qhov tseeb, cov fittings saum toj no yog suav tias yog qhov zoo dua li siv cov qhab nia ntawm kev coj ua xws li 304, 304L, 316 thiab 316 thiab 316 thiab 316 thiab 316 thiab 316 thiab 316L. Cov alloys tau siv rau cov hlau stainless 317L tau paub los muab tshuaj tiv thaiv zoo dua 316L, tshwj xeeb yuav muaj cov tshuaj lom neeg xws li cov khoom siv sulphevur xws li cov xov xwm, chlorides thiab lwm yam.

Cov khoom siv Dulex tau muab rau ntau yam kev lag luam xws li tso tsheb hlau luam brewing, boiler siv thiab desalination nroj tsuag. Peb npaj tag nrho kab ntawm 2205 lub fittsex fittings kom tau raws li koj cov kev cai xa khoom.

Tus qauv ntawm 2205 duplex stainless hlau muaj cov pas dej ntawm austenite ib puag ncig los ntawm cov theem ruaj khov. Hauv lub xeev nyuaj, 2205 muaj kwv yees li 40-ib nrab ferrite. Duplex cov hlau tau txais txiaj ntsig zoo ib yam thiab cov lerritic ferritic ntawm cov motivtructure microstructure. Ferritic alloys muab lub zog tiv thaiv kev ntxhov siab tawg, thaum Austenitic alloys muaj yooj yim yooj yim ntawm kev tsim khoom thiab xeb tsis kam. Cov tubular fittings ua hauj lwm nyob rau hauv acid txo thiab oxidizing tej yam kev mob thiab hauv cov khoom tsim hauv tsev hauv cov nroj tsuag desulfurization.

Lub siab dua cov nitrogen cov ntsiab lus, qhov zoo dua rau corrosion tsis kam. 2205 fittings yog qhov xav tau rau cov cim tshwj xeeb thiab kev ua tau zoo lawv pom hauv lawv daim ntawv thov. Cov khoom no yog tsim thiab xa tawm hauv ntau yam duab thiab ntau thiab tsawg thiab tsawg yog cov neeg siv khoom. Cov kav dej no tau thauj mus rau ntau qhov kev lag luam suav nrog cov khoom lag luam cia khoom siv, cov khoom siv boiler ntau thiab cov nroj tsuag desalination. Qhov feem pua ​​ntawm cov khoom siv alloy siv hauv kev tsim cov fittings thiab duplex cov kav hlau tsis muaj nqi qis dua.

Lawv lub peev xwm los lis cov khib nyiab thiab cov tshuaj tua kab mob hnyav tsis muaj cov roj av dupposion xws li flule roj desulfurization, tshuaj lom ua cov nroj tsuag, thiab ntau dua. Txawm hais tias Duplex alloys yog qhov haum rau cov txheej txheem kub siab, A815 tsis pom zoo vim tias lub taub dej kub dhau 600¡Ãf.

253 ma cov yeeb nkab fittings yog ustenitic stainless hlau npib tsib xee-chromium aloyoed haum nrog lub ntiaj teb sib txawv thiab nitrogen. Cov fittings muaj cov oxior oxidation tiv taus txog li 1150 degree c thiab General corrosion tsis kam. Nws muab lub zog zoo tshaj plaws nrog rau cov kev tiv thaiv zoo dua rau kev yaig thiab sulfidation ntawm kub siab. Los ntawm kev tswj kom nruj ntawm micro-alloy ntxiv cov qauv qhia tau superior kub tiv taus cov khoom. Cov fittings muaj cov kev pib ua kom zoo dua thiab tswj hwm nws cov kev tsim nyog. Lub xub ntiag ntawm nitrogen thiab chromium cov ntsiab lus muaj rau pitting thiab kev ntxhov siab corrosion tawg.

2205 yog cov neeg siv ntau tshaj plaws (Ferrritic \ / ustenitic) stainless hlau yeeb nkab fittings. Nws yog siv vim nws zoo heev corrosion tsis kam thiab muaj zog siab. FuPleX S31803 fittings muaj kev yeem ua tau zoo ntawm corrosion tsis kam, tab sis feem ntau cov duplex s31803 cov tsim tawm tau ua raws li Duplex S31803. 1.4462 belongs rau lub duplex steel series. Cov hlau no muaj ntau dua corrosion tsis kam dua li org austenitic 1.4404. Yog li ntawd, lub tensile tau taw tes yog kwv yees li 150% siab dua.
