UNR UNSG UNR55 SUPPER DUPLEX SQUPURE steel bar zoo rau cov kev pabcuam xoom

Raws li qhov tshwm sim, qhov no yog cov khoom haum zoo rau cov ntawv thov cuam tshuam nrog ib puag ncig muaj chlorides thiab thiab hydrogen sulphide. Cov nitrogen ntxiv rau S31803 Duplex Flanges txhawm rau txhim kho cov xwm txheej no, uas tsis yog kho corrosion tsis kam, tab sis kuj tau welds zoo. ASTM A182 F51 flanges xa mus rau cov yeeb nkab flanges ua los ntawm forged duplex stainless hlau unsolutless steel stainless hlau uncenolle stainless hlau uncenolle stainless hlau Unceness Systems.

Nws yog dav siv nyob rau hauv cov roj pov thiab roj kev tshawb nrhiav \ / ntau lawm thiab hauv kev hloov cua sov hauv petrochemical \ / tshuaj lom neeg.

ASTM A240 Hom 2205 Phaj yog lub Duplex phaj yog siv ntau yam kev lag luam xws li kev ua yeeb yam, roj thiab roj kev tshawb nrhiav, thiab marine engineering. Sa 240 gr 2205 daim ntawv yog tsim los ntawm qib 220) stainless hlau, uas yog kev sib xyaw ntawm ferritic thiab ustenitic steel.

Lub Flange yog qhov thib ob feem ntau siv koom nrog txoj kev tom qab selding. Kev siv flanges tau siv thaum cov pob qij txha xav tau dismantling. Nws muab kev hloov tau rau kev saib xyuas. Flange txuas cov yeeb nkab nrog ntau yam khoom siv thiab li qub. Breakup Flanges tau ntxiv rau hauv cov raj xa hluav taws yog tias kev saib xyuas tsis tu ncua thaum lub sijhawm cog ntoo.

Duplex stainless hlau yog ib tug heev pab tau cov hlau uas siv tau lub ntiaj teb dhau. Nws tau txais nws lub npe los ntawm qhov tseeb tias nws muaj ob qib sib txawv ntawm cov hlau. Qhov tseem ceeb, duplex yog FE-NI-CR ALLOY uas muaj ob-theem Ferritic-Austenitic-Ausenitic Stainless-Autructure thaum nws nyob ntawm chav tsev kub.

Tus Austenitic-Ferritic stainless variant nrog kev ntxhov siab ntau dua corrosion nrawm 304 thiab 316 Stainless thiab cuam tshuam lub zog.

Cov khoom muaj lub zog muaj zog. Qhov tsawg kawg nkaus tau muaj zog yog 450mpa thiab lub zog tsawg tshaj plaws yog 620mpa, nrog 25% tsawg kawg elongation thiab 290HB Brinell Hardness.

Lub zog: Duplex Stainless hlau muaj kwv yees li ob lub zog ntawm cov hlau tsis tu ncua lossis cov hlau ferritic stainless.

Txhawm rau kom xa cov raj xa dej, nws yog ib qho tsim nyog los tshem cov hose ncaj hauv cov raj xa dej. Thaum siv ntau lub raj xa dej, ntau yam kav dej yuav tsum tau siv. Thaum twg cov raj xa dej siv, lub luj tshib yuav tsum tau siv los hloov qhov loj ntawm cov raj xa dej. Thaum bifurcating, peb-txoj kev xaim cov flange kev sib txuas siv thaum lub raj xa hluav taws xob thiab kev sib txuas txias thiab kev sib tw txias thiab kev sib koom ua ke txias. , Hauv kev sib txuas ntawm ntau cov twj paj nruag, kuj tseem muaj cov txuas txuas thiab ntsaws ntawm cov twj paj nruag theem.

Super Duplex Stainless Hlau muaj cov zoo tib yam raws li nws cov counterx counterpart. Lub ntsiab sib txawv ntawm ob qho yog tias super duplex muaj qhov ntau dua chromium thiab molybdenum cov ntsiab lus, ua rau muaj kev tiv thaiv corrosion.

Tougness thiab ductility: duplex stainless hlau tshaj li lub ferritic qib txawm tias lawv tsis yog li kov cov qhab nia ntawm Austenic.

Ib txoj kev sib koom ua ke flanged yog tsim ntawm peb cais thiab ywj siab yog tias muaj kev sib cuam tshuam; Cov flanges, lub gaskets, thiab cov bolting; Uas tau sib sau los ntawm kev cuam tshuam lwm tus cuam tshuam, fitter. Cov kev tswj tshwj xeeb yuav tsum muaj nyob rau hauv kev xaiv thiab kev xaiv ntawm tag nrho cov muaj cov ntsiab lus kom muaj kev sib koom ua ke, uas tau siv tau xau nruj.

Cov txiaj ntsig lub zog ntawm no alloy yog li 570 MPA. Ntxiv rau lub zog, A240 s32750 sup duplex phaj yog ib qho alloy uas muab qhov zoo tshaj plaws tsis kam lees cov crevice thiab pitting corrosion.

A182 gr. F51 \ / S31803 cov khoom siv yog ib qho duplex stainless hlau, uas muaj kwv yees li 50% ferrite thiab 50% austenite.

Cov kev ntsuas siab ntawm cov khoom raug xaiv los ntawm cov chav kawm 150lbs txog 2500lbs. Muaj ntau hom sib txawv ntawm cov duplex f51 flanges xws li lub ntsej muag tsa, ntiv nplhaib hom sib koom ua ke thiab tiaj tus ntsej muag flanges.

Siab chromium, molybdenum thiab nitrogen cov ntsiab lus cuam tshuam nrog pitting tsis zoo rau cov medtenatent thiab corrosive corrosive conduction, thiab tseem ceeb pitting txias rau tag nrho cov xov xwm, thiab tseem ceeb pitting txias rau saum 50¡Ãc.

Hauv cov hlau yas, chav kho kom muaj micructubre muaj lub zog siab ntawm cov qib siab thaum khaws cov qib corrosion thaum khaws cov qib tsis kam ntawm cov qib tsis zoo. Nws tsis yog qhov tsis yooj yim los siv cov hlau no ua cov kev daws teeb meem rau chloride-ntxias kev ntxhov siab tawg, pob taws Achilles ntawm cov hlau tsis xeb hlau.

Qhov 21% chromium cov ntsiab lus yog tus yuam sij rau huab corrosion tsis kam thiab lub zog ntawm sa 182 f51 flanges. HT cov yeeb nkab yog cov khoom lag luam thiab chaw tsim khoom ntawm cov flanges hauv ntau teev nyob rau ntau teev, duab thiab hom.

Corrosion Kuj: raws li nrog txhua tus stainless hlau, corrosion tsis yog nyob ntawm cov muaj pes tsawg ntawm cov khoom siv roj stainless, nrog chromium, molybdenum thiab nitrogen cov ntsiab lus yog qhov tseem ceeb tshaj plaws. Duplex stainless hlau yog heev corrosion resistant thiab txawm nyob hauv chloride thiab sulphide ib puag ncig kev ua kom muaj kev ntxhov siab corrosion (SCC). SCC yog hom corrosion uas tshwm sim thaum ib qho kev teeb tsa tshwj xeeb tam sim no: tensile kev nyuaj siab, ib puag ncig corrosive thiab qhov kub txaus.

Super DuPleX undllex uncen S32750 Bar tau ua tau zoo heev rau kev ntxhov siab corrosion tawg hauv chlorine muaj chaw ib puag ncig. Tom qab cua sov rau kev daws teeb meem kev kho kom sov ntawm 1080¡Ãc mus rau 1120¡Ãc, quenching yuav tsum muaj.

A789 unc unic s31803 thiab unspes ob qib ntawm ob chav stainless hlau uas tau siv dav hauv ntau cov ntawv thov. Cov txiv neej duplex s31803 Seamless kav yog paub rau lawv cov txiv neej ua hauj lwm zoo, muaj lub zog siab, thiab weldability thiab zoo weldability. A789 yog ib qho tshwj xeeb uas tau them seamless thiab welded tub ua los ntawm duplex steel stainless hlau.
ASTM A479 DUPLEX STEEN Unasers unreakers muaj cov hlau vuam, ntshav arc vuam, submerged arc vuam thiab roj tungsten arc vuam. ASME SA 479 DUPLEX STEEN UNSER S31803 Square Washer yog ib qho Ferritic, Ausenitic 22% Molybdenum thiab 5-6% Nickel Alloy Steel.
Ib Flange yog ib qho kev tawm tsam, daim di ncauj lossis sab nraud, tog twg los sab nraud lossis sab hauv, uas yog cov nqaj hlau xws li ib tug t-nqaj); Rau cov ntawv yooj yim tau yooj yim \ / hloov ntawm kev sib cuag nrog lwm yam khoom (raws li flange thaum kawg ntawm cov yeeb nkab, chav dej lub tog raj kheej, lossis ntawm lub ntsej muag lub koob yees duab); Los yog rau kev ruaj khov thiab taw qhia kev txav ntawm lub tshuab lossis nws cov ntu (raws li sab hauv flange ntawm tsheb ciav hlau lossis lub log los ntawm kev khiav tawm ntawm cov ciav hlau). Lo lus "Flange" kuj yog siv rau hom cuab yeej siv los ua cov flanges.

Cov Oxidation siab tiv taus cov khoom ntawm qib 2205 yog margred los ntawm nws embrittlement saum 300¡Ãc. Qhov no puag txoj kev tuaj yeem hloov kho los ntawm kev daws teeb meem tag nrho anealing. Qhov qib qib kawm tau zoo nyob hauv qab 300¡ling.

Peb muab cov kev ua tiav ntawm 2205 duplex steel footeners xws li bolts, neeg rau, ntxuav, txuas cov pas nrig thiab ob leeg steel screws. Peb kuj muaj super duplex fasteners nyob rau ntau thiab tsawg, cov duab, nta thiab tuab raws li cov neeg siv khoom.

2507 kav dej kuj tseem yuav muaj hluav taws xob hluav taws xob welded. Cov Pipes Cov Chaw Tsim Tshuaj yog nyob hauv tsib chav kawm sib txawv nrog txhua chav kawm muaj cov khoom siv neeg kho tshuab tshwj xeeb. Lub hluav taws xob tiv thaiv welded kav muaj zog thiab lawv tuaj yeem siv rau vuam dav dav.

Raws li qhov tshwm sim, qhov no yog cov khoom haum zoo rau cov ntawv thov cuam tshuam nrog ib puag ncig muaj chlorides thiab thiab hydrogen sulphide. Cov nitrogen ntxiv rau S31803 Duplex Flanges txhawm rau txhim kho cov xwm txheej no, uas tsis yog kho corrosion tsis kam, tab sis kuj tau welds zoo. ASTM A182 F51 flanges xa mus rau cov yeeb nkab flanges ua los ntawm forged duplex stainless hlau unsolutless steel stainless hlau uncenolle stainless hlau uncenolle stainless hlau Unceness Systems.

Duplex cov hlau muaj ntau dua kev nruj thiab zoo dua weldability. Qhov no yog li cas alloy siv phaj yog siv rau kev lag luam kev lag luam muaj siab.

Vim yog lub alloy's high tshuab zog heev, dual-theem cov khoom lag luam ceev ntawm lawv cov qauv ntawm cov khoom lag luam uas zaum kawg, ua pov thawj tus nqi txuag rau lwm cov hlau stainless.

Lawv tiv taus kev corrosion dav. Peb yog cov neeg muab khoom ntawm ASME SA182 Duplex Steel unc undliges rau cov dej hiav txwv thiab cov cuab yeej siv hluav taws xob.
