Super Duplex S32750 Flange Unvential S32750 Xov Flanges

Rau ntau cov ntawv thov uas 300 series stainless hlau yog qhov raug rau cov chloride kev ntxhov siab tawg, 2205 duplex stainless hlau yog qhov kev daws teeb meem zoo. Kev ntxhov siab corrosion tawg tshwm sim thaum stainless hlau yog raug rau tensile muaj kev ntxhov siab thaum sib cuag nrog cov kev daws teeb meem uas muaj chlorides. Kev kub siab dua kub kuj nce ntxiv qhov kev ua kom muaj kev phom sij ntawm cov hlau tsis muaj mob corrosion.

Cov hlau duPlex uns s31803 siv rau hauv cov khoom siv marine engineering, roj tov kev sib pauv, cov khoom siv hluav taws xob, roj thiab roj ua khoom lag luam.

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.
Nyob rau ntawm qhov kub no, ob tus hlau steel flanges tshaj 300 degrees Celsius tseem muaj kev tiv thaiv los ntawm kev sawv los ntawm kev xeb vim tias corrosion. Ciav muaj peev xwm kuj tau zoo heev thaum kub tsawg. Fabrication yog ua tiav tsuas yog nrog cov cuab yeej muab rau cov khoom siv hlau stainless. Yuav tsum tau huv kom zoo ua ntej siv. Qhov no yog ua los tiv thaiv cov hlau stainless los ntawm kev sib kis ntawm corroding hlau.
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.

Rau ob lub stainless hlau flanges, tov annealing ntawm qhov ntsuas kub kom tsim nyog tuaj yeem ua tiav cov kev sib npaug zoo tshaj plaws ntawm theem. Nws yog ib qho tseem ceeb kom lub sijhawm nruab nrab ntawm kev tawm hauv lub cub tawg thiab dej quenching li luv tau. Qhov no yog kom txo qhov kub cua sov los ntawm flange, uas tuaj yeem ua rau muaj nag kev ua ntej dej tso tseg ua ntej tso dej sov.

Qhov no alloy yog tshwj xeeb tshaj yog pab tau nyob rau hauv cov -50¡ÃF \ / + 600Ãf kub. Rau cov ntawv thov sab nraum qhov kub thiab txias no, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog siv hauv Welded qauv.

Duplex 2205, tsis yog S32205, yog cov khoom siv stainless hlau uas muaj cov microstructure muaj sib npaug muaj sib npaug ntawm cov ferrite thiab austenite. Cov qib no yog hom nrov tshaj plaws, thiab ob hom khoom siv ob-theem no yog qhov tseem ceeb tshaj 316 stainless hlau nyob rau hauv cov nqe lus muaj zog thiab corrosion tsis kam.

Taub qab vuam flanges yog drilled (machined), thiab phab ntsa tuab ntawm flange yog tib qho loj li cov yeeb nkab sib xyaw. Lub sib dua lub raj, cov cheeb tsam loj dua, thiab hloov kho lub raj, cov kab me me. Peb cov hauv pob tw weld flanges, taub qab weld flanges feem ntau yog siv rau kev kub siab, tsawg kub lossis kub.

Duplex stainless hlau flanges tau dav siv nyob rau hauv cov pipeline tshuab, risers, manifolds, thiab kuj nyob rau hauv lub pethoden kev lag luam nyob rau hauv daim ntawv ntawm siab cov hlab thiab pipelines. Duplex 2205 Flange cov khoom muaj lub zog zoo thiab lub siab tsis kam rau corrosion, pitting thiab crevice corrosion. Lub nominal tshuaj muaj pes tsawg leeg ntawm duplex 2205 yog 22% chromium, 3.2% molybdenum, 5% npib tsib xee thiab lwm yam alloy thiab nitrogen.

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.
Nyob rau ntawm qhov kub no, ob tus hlau steel flanges tshaj 300 degrees Celsius tseem muaj kev tiv thaiv los ntawm kev sawv los ntawm kev xeb vim tias corrosion. Ciav muaj peev xwm kuj tau zoo heev thaum kub tsawg. Fabrication yog ua tiav tsuas yog nrog cov cuab yeej muab rau cov khoom siv hlau stainless. Yuav tsum tau huv kom zoo ua ntej siv. Qhov no yog ua los tiv thaiv cov hlau stainless los ntawm kev sib kis ntawm corroding hlau.
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.

Duplex lub zog siab dua thiab cov tshuaj lom neeg yog offset los ntawm nws cov teeb meem formarity. Cov qib kawm tau zoo rau kev sib txuas yooj yim flanged rau cov kev pabcuam tsau, tab sis tsis tshua muaj txiaj ntsig thaum ua cov qauv hlau ua ke. Hmoov zoo, tshuab luam ntawv ntawm ob theem steels nyob rau hauv cov qauv yas thiab puag ncig yog tsis yog qhov kev nyiam loj hauv cov ntawv thov tsis yog corrosive.

Qhov no nyeg hnov ​​cov qoob loo zom cov qoob loo, tsis muaj zog thiab corring nws. Qhov txiaj ntsig ntawm vuam alloy 2507 dig muag Flanges yog tias cov chemetistry hauv lawv cov alloy muaj cov ntsiab lus muaj roj carbon tsawg heev. Qhov no ua rau nws nyuaj rau tsim carbide precipitates thiab inadvertasently tiv thaiv intergranular corrosion.

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.

Vim nws cov ntsiab lus siab hauv no cuam tshuam stainless hlau, tus qib no tseem hu ua 22 cr duplex steel. Duplex Stainless hlau 2205 Flange Sorf yog cov qeb ntau tshaj plaws ntawm cov hom stainless hlau stainless. Ib qho kev sib raug zoo ntawm 22 cr duplex phaj flanges yog siab xa lub zog. Qhov tseeb, lub zog tensile ntawm qib tshwj xeeb no feem ntau yog ob zaug lossis ob zaug ntawm cov qauv kev txhawb nqa cov qauv.

Nws tseem zoo heev rau lub zog li cov khoom siv tau zoo tshaj plaws ntxiv dag zog. Nitrogen yog ib qho muaj zog Austenite yav tas los qub, thiab ntxiv rau ntawm nitrogen zoo heev txhim kho cov tawv ntawm ob theem steels. Nws kuj ncua qhov tsim ntawm intermetallic cov tebchaw txaus kom tso cai rau kev ua thiab FOORICE ntawm ob hom hlau. Nickel yog ib qho kev siv tsis huv uas txhawb kev tsim ntawm Austenitic FCC qauv, uas ua rau muaj kev sib zog ntawm ob theem steels.

Cov kev loj-lub zog flanges muab kaw cia ntawm ntau yam kav dej kav dej. Folifunctional flange qhia zoo ruaj ruaj thiab cov khoom pov thawj txhim kho kom tsis txhob muaj chloride pitting hauv cov ntawv thov marine. Nrog cov qauv vuam cov txheej txheem, Super Duplex Flanges tuaj yeem muab tso rau yooj yim rau cov raj xa khoom sib txawv.

Stainless hlau qib muaj ntau dua 12% chromium hauv cov alloy tiv taus cov teebmeem ntawm oxidation. Nyob rau hauv cov ntaub ntawv ntawm super duplex stainless hlau 2507, nws alloy muaj 25% chromium, uas txhim kho oxidation tiv taus txawm tias kub.
