Daim Ntawv Thov Cov Hlau Stupless:

Super Duplex Flanges Siv cov hmoov av ntshiab uas muaj kev sib xyaw nrog cov roj av thiab qib siab micrtritures thiab siab molybdenum thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus. Cov tshuaj lom neeg zoo tshaj plaws ua ke muab cov tshuaj tiv thaiv zoo dua thiab muaj zog ntxiv. Cov khoom peb tsim tau siv nyob rau hauv ntau cov kev siv thiab kev lag luam. Cov flanges no yog cov tiv taus zoo hauv kev xeb, acidic thiab txo qhov chaw ib puag ncig.

Cov khoom siv S32205 DuPlex Asme asme sa182 pob tw Weld Flanges yog tsim nyog rau dej hiav txwv thiab cov khoom siv hluav taws xob tuaj yeem tiv thaiv kom sov txog 600,000Ãf, thaum tseem muaj cov yam ntxwv zoo.

Lub ATM A182 F53 F53 FRE UNL UNST S32750 Flange yog nyob rau hauv ASTM A182 cov lus qhia tshwj xeeb rau kev kub siab thiab kev siab siab.

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.

Cov flanges tau muaj kev tiv thaiv zoo heev hauv cov kua qaub xws li nitric acid, thiab lwm yam ntxiv, peb lub qhov cub ua kom zoo nyob hauv cov tshuaj hiav txwv thiab cov tshuaj chloride. Peb cov kws tshaj lij yog tsim Dl theem steel f60 nrog cov khoom muaj zog xws li kev tsim khoom, yooj yim heev ua tiav thiab siv sijhawm ntev.

Qhov no yog tsim los txuas nrog cov kav dej los ntawm taub qab vuam. Nws yog tus nqi kim vim nws lub caj dab ntev, tab sis yog nyiam rau kev siv kev ntxhov siab siab. Lub caj dab lossis hub hloov mus rau hauv qab ntawm lub hub rau lub phab ntsa tuab ntawm lub pob tw wandd, muab qhov tseem ceeb ua rau lub ntsej muag zoo. Flange qhov sib phim cov yeeb nkab qhov kom txo tau cov kev kub ntxhov thiab kev yaig.

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.

Cov ntawv thov suav nrog cov ntawv thov kev ua kom haum nrog cov ntaub ntawv acidic vim yog cov ntaub ntawv muaj pes tsawg leeg.

Lub taub hau tsim ntawm pob tw ntawm pob tw weld flanges muab ib qho kev sib txuas muaj zog heev, thiab pob tw weld flanges tuaj yeem ua tau ntau yam tsis muaj cov ntaub ntawv sib cuam tshuam thiab muaj / lossis kev sib txuas zoo. Taub qab Weld Flanges tseem muaj qhov zoo dua ntawm kev ua tau zoo rau huab siab siab thiab qis.
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.

SA 182 F53 S32750 Flange yog super duplex stainless hlau stainless muab rau hauv cov dej kub thiab kev daws teeb meem kev daws teeb meem.

Kev sib xyaw ntawm Ferritritic theem thiab Austenitic theem muab ob lub zog siab thiab zoo heev corrosion.

ASTM A182 F51 Flange yog ua cov roj carbon, chromium, mangelese, siosphorus, cov leeg qaib, nitrogen, molybdenum thiab hlau.

Qee qhov dual-theem weld flanges muaj cov oxidation zoo tsis kam ntawm qhov kub tshaj 300 qib qis dua 300 degrees raug rau 475 degrees Celsius. Cov theem qib ob steel s32205 ntiv nplhaib sib koom ua ke kuj tseem muaj kev ua kom muaj zog thiab kev qaug zog zoo li cov khoom lag luam thermal thiab ntau dua thermal conductivity tshaj li tau lees paub.

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.

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.

Duplex flanges yog ob lub micrtructures muaj cov qib tsis muaj kev sib cav thiab qib siab. Cov qib tau ntau yog tsim nrog cov tshuaj lom neeg zoo heev ntawm chromium, npib tsib xee thiab me me ntawm molybdenum. Qhov kev xav zoo tshaj plaws ua rau cov qauv no ntxiv rau kev txhoj puab heev thiab oxidizing media.

Lub Koom Haum Thawj Ntawm Cov Qauv Duplex thiab cov khoom siv Super Duplex flanges yog qhov super duplex muaj cov ntsiab lus ntau dua ntawm ob lub molybdenum thiab chromium lawv alloy.

¤ ¤ cov hlab ntsha siab, kev tso tsheb hlau luam siab cia, kev hloov pauv kub (kev lag luam kub (siv tshuaj lom neeg ua lag luam).

Super Duplex Flanges Siv cov hmoov av ntshiab uas muaj kev sib xyaw nrog cov roj av thiab qib siab micrtritures thiab siab molybdenum thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus thiab chromium cov ntsiab lus. Cov tshuaj lom neeg zoo tshaj plaws ua ke muab cov tshuaj tiv thaiv zoo dua thiab muaj zog ntxiv. Cov khoom peb tsim tau siv nyob rau hauv ntau cov kev siv thiab kev lag luam. Cov flanges no yog cov tiv taus zoo hauv kev xeb, acidic thiab txo qhov chaw ib puag ncig.

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 ntawv thov suav nrog cov ntawv thov kev ua kom haum nrog cov ntaub ntawv acidic vim yog cov ntaub ntawv muaj pes tsawg leeg.

Super Duplex 2507 Taub Hau Weld Flanges tau txhim kho corrosion tsis kam, ua rau lawv tus kheej haum rau kev tawg, pitting, yaig, yaig thiab dav corrosion. Vim yog cov yam ntxwv ntawm duplex thiab super duplex pob tw weld flanges, lawv feem ntau siv hauv kev lag luam tshuaj, petrochemical, khoom siv fais fab thiab dej hiav txwv.

Tsis tas li ntawd, 2205 stainless hlau flanges ua rau muaj zog nkees nkees thiab ua tau zoo rau chloride kev ntxhov siab tawg. Cov cuab yeej ntxiv ntawm Duplex 2205 flanges suav nrog kev tiv thaiv zoo rau cov crevice corrosion, erosion corrosion, erore corrosion thiab dav dav corrosion thiab dav dav ib puag ncig.

Duplex steel flanges yog tsim los txhim kho kev pitting caterposion, siab zog, kev nyuaj siab corrosion, crevice corrosion thiab tawg. Duplex Steel zawv zawg Flanges tiv thaiv sulfide kev nyuaj siab corrosion thiab chloride ib puag ncig. Duplex Steel tiaj Flanges yog ib qho tseem ceeb ntawm cov tsev neeg ob lub flange.

Duplex 2205 flanges muaj tus ducast kom nkev hloov ntawm -50¡Ãc thiab tseem ua tau nkig ntawm 300-15Ãc mus rau 300¡x. Raug rau saum 300 yuav tsis tsuas yog ua rau embrittlement ntawm 2205 flange, tab sis yuav txo cov corrosion tsis kam.

Lub hauv paus lub cev ntawm lub din 1.4462 flange muaj ob qho qauv ferritic thiab Austenitic. Lub duality ntawm lawv microstructure pauv tsis tsuas yog cov cuab yeej kho tshuab tab sis kuj yog lawv cov khoom lag luam dorrosion. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm uns s31803 weld flanges muaj 22% chromium, 3% molybdenum, thiab 5% rau 6% npib tsib xee.

Chromium, Molybdenum, nitrogen thiab npib tsib yog qhov tseem ceeb tshaj plaws ntawm cov tshuab, lub cev thiab corrosion thaj chaw ntawm cov hlwv ntawm ob lub stuple. Chromium yog qhov tsim nyog los tsim cov chromium passivation zaj duab xis txaus los tiv thaiv hlau los ntawm cov huab cua tsis huv. Ntau dua cov ntsiab lus chromium, qhov zoo dua rau corrosion tsis kam.
