Muaj ntau hom sib txawv ntawm cov flanges xws li plam ntawm flanges, (fled flanges, feded flanges, liab plawg, txo cov flanges thiab ntau yam los ntawm lawv cov haujlwm.

Duplex thiab Super Dupluam flanges yog qhov zoo tagnrho rau kev nthuav dav zoo, thiab ntsuas kub thiab nws qhov tseem ceeb yog tias nws tsim nyog rau cov ntawv thov siab.

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.

Super Duplex Flanges yog muaj kev sib luag heev. Qhov no alloy tuaj yeem yooj yim welded los ntawm ntau hom vuam ua haujlwm. Cov fluplex no yog paub rau lawv lub zog nkees nkees thiab muab lub zog siab ntawm qhov kub kub hauv qhov kub tsawg dua.

Qhov ntau ntawm cov chav hlau ob 2205 orifice phaj flanges npog txhua cov ntaub ntawv txheem cov qauv, ntau thiab tsawg thiab cov ncauj lus tshwj xeeb. Cov roj av chav me dawb 2205 flanges yog dav siv nyob rau hauv ntau qhov kev pab cuam uas muaj kev lag luam thiab txhim kho kev lag luam thiab txhim kho kev txhim kho kom zoo dua qub thiab ua tau zoo.

Duplex stainless hlau s31803 \ / s32205 \ nrog zoo sulfide kev nyuaj siab corrosion, muaj lub zog zoo thiab zoo heev kev cuam tshuam todlaj. These dual phase steel S31803 slip flanges are chemically balanced to produce a microstructure of approximately 50\/50 ferrite to austenite ratio.

Flanges kuj muaj ntsej muag sib txawv xws li tsa ntsej muag, tiaj tus ntsej muag thiab suab sib koom ua ke. Flange daim ntawv thov muaj nyob hauv iberospace, nuclear engineering thiab tshuaj siv tshuaj lom neeg. Duplex stainless hlau taub qab weld flanges muaj lub caj dab weld rau kev tuav ntxiv ua ntej thiab tom qab vuam.

2205 flanges muaj kev tiv thaiv zoo heev rau pitting thiab crevice corrosion, ua tau zoo nyob rau hauv feem ntau corrosive ib puag ncig, thiab muaj kev weldability zoo. Cov lus qhia tshwj xeeb no ob theem steel steel s31803 feem ntau kub hnyiab s31803 feem ntau yog ua rau muaj qhov kub ntawm 300 degrees raug rau 475 degrees Celsius.

Duplex cov hlau tsis yog qib s32205 chav hlau duplex yog resistant rau chloride ib puag ncig thiab sulfide kev nyuaj siab corrosion. Nws cov txiaj ntsig lub zog yog kwv yees li ob zaug uas ntawm cov qauv kev ua kom muaj kev sib tw ntawm cov qib tsis zoo. Cov hlau DuPlex uns s32205 flanges yog qhov ruaj khov thiab tseem tuaj yeem tau yooj yim rau txhua qhov loj ua tsaug rau cov duab sib txawv thiab ntau thiab tsawg.

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.

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.

Rau cov qauv kev ua kom muaj kev sib tw ntawm cov qib tsis zoo (xws li 304 thiab 316), SCC tuaj yeem yog qhov teeb meem uas muaj av noo thiab muaj qee yam tshuaj lom li chlorides. Yog li ntawd, Duplex dig muag Flange cov neeg muag khoom feem ntau muab lawv rau kev lag luam xws li roj thiab muaj kev lag luam, kev lag luam petrochemical thiab marine.

Cov tshuaj lom neeg cov tshuaj lom neeg ntawm cov roj duplex f51 muaj cov pa roj carbon, chromium, mancese, molybdenum, npib tsib xee thiab phosphorus. Flanges tau siv rau hauv siab nruab nrab thiab cov fittings valve.

Cov khoom siv A182 F51 muaj cov pa roj carbon, 2% manghologes, Phosphorus, Sulfur, Chromium, chromium, 4.5% molybdenum thiab nitrogen nws.

Super Duplex flanges yog qhov zoo tagnrho rau kev pabcuam hauv cov chaw muaj kev tiv thaiv hnyav xws li ntug dej hiav txwv thiab marine. Nws tseem yog tshwj xeeb tiv thaiv chloride SCC. Flanges muab sib npaug pitting kuj, kom ntseeg tau zoo heev pitting kuj. Tag nrho cov khoom lag luam muaj lub zog kuaj, suav nrog pitting corrosion kev sim, kev kuaj tawv, tshuaj ntsuam thiab ntsuas micro thiab ntau dua.

Duplex 2205 yog tus cwj pwm los ntawm cov siab tiv thaiv rau cov chloride kev ntxhov siab, zoo sulfide kev tawm tsam corrosion, siab lub zog thiab weldability thiab weldability.

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.

Txawm hais tias nws yog ib qho tseem ceeb kom nco ntsoov tias pitting corrosion tuaj yeem muaj kev txhawj xeeb hauv cov tshuaj chloride thaum oxidizing xov xwm tam sim no. Nyob rau hauv cov mob no, lub passive (tiv thaiv) txheej ntawm lub duplex 2205 cov khoom siv tuaj yeem cuam tshuam hauv pittingcompized yuav tshwm sim.

Cov ntsiab lus chromium yog li ntawm 20-28%, uas yog vim li cas uns uns uns uns tsis s31803 \ unson1205 dig muag flanges yauv tsis txaus siab hu ua passivation. Nyob rau hauv qhov xwm txheej no, kev kho tus kheej txoj kev tiv thaiv nws tus kheej passivating oxide txheej nyob ib puag ncig lub flange ua nws tiv taus oxidation.
