Duplex flanges yog ua los ntawm cov hlau tshwj xeeb nrog cov tshuaj austenitic thiab ferritic metallurgical nta hauv nws cov microstructure. Cov no yog cov hlau nplaum sib nqus nrog cov kev ua siab loj thiab ua haujlwm tawv.

Taub qab weld flanges yog flanges tsim los txuas rau cov tshuab luam ntawv los ntawm taub qab vuam. Hom flange no los ntawm ntau qhov ntau thiab tsawg, pob tw weld flanges yog kim vim yog cov yeeb nkab lossis haum, tab sis yog nyiam rau kev siv ntxhov siab siab. Caj dab lossis hub hloov kev ntxhov siab rau cov yeeb nkab.

Taub qab weld flanges yog flanges tsim los txuas rau cov tshuab luam ntawv los ntawm taub qab vuam. Muaj ntau ntau yam tshwj xeeb ntawm flange. Taub qab Weld Flanges yog kim vim tias lawv cov neeg ua haujlwm ntev dua thiab cov neeg ua haujlwm siab rau kev sib chwv nrog cov ntawv thov kev ntxhov siab siab. Caj dab lossis hub hloov kev ntxhov siab rau cov yeeb nkab.

DupleX Steel Flanges tau siv dav hauv kev siv tshuab siv, kev lag luam tshuab thiab tsheb lag luam hauv tsheb. Duplex steel s31803 lap flanges yog qhov zoo tagnrho rau cov ntawv thov ua kom zoo dua li hom 316 thiab lub zog kub zoo. Peb muaj lub duplex steel s31803 \ / s32205 flanges hauv Tshuag. Duplex steel flanges yog ib txwm siv hauv tshuaj, petrochemical, thiab kev lag luam fais fab.

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.

Lawv muaj tus qauv tsim uas tso cai rau cov kav dej kom dhau los ntawm cov flange thiab nrhiav qhov tseeb taw tes rau kev sib txuas. Lub ASTM A182 Qib F53 WNRF Flange muaj lub caj dab welded tsa ntsej muag.

Taub qab Weld Flanges yog hom nrov tshaj plaws ntawm kev kub siab pipeline flange. 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.

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.

Chromium yog ib tug ferrite yav dhau los, uas txhais tau tias nws txhawb nqa cov qauv BCC qauv ntawm cov hlau. Nws kuj tseem nce oxidation tiv thaiv nyob rau ntawm qhov kub. Siab chromium kuj txhawb kev tsim ntawm intermetallic theem, uas yog detrimental rau Duplex stainless hlau thiab yuav tsum tau hais.

Kev sib xyaw ntawm chromium, molybdenum thiab nitrogen muab 2205 zoo tsis kam rau chloride pitting thiab crevice corrosion. Qhov kev tiv thaiv no yog qhov tseem ceeb tshaj plaws rau cov kev pab, cov dej brackish, cov dej num ua kom dawb, kaw cov ntaub ntawv ua zaub mov noj thiab qee qhov kev siv zaub mov noj. Lub siab chromium, molybdenum thiab nitrogen cov ntsiab lus ntawm 2205 muab kev cuam tshuam zoo dua li 317L thiab 317l thiab cov neeg pej xeem tau koom nrog ua kom zoo tshaj plaws rau peb cov neeg siv khoom.

A182 f51 F51 FRLEX Stainless hlau muaj txog 21% chromium, 2.5% molybdenum thiab 4.5% npib tsib xee-nitrogen alloy. Nws muaj lub zog siab, cuam tshuam zoo heev nruj thiab zoo tag nrho thiab kev ntxhov siab hauv cheeb tsam kev tiv thaiv.

Nws tseem yog tshwj xeeb tsis kam rau chloride SCC. Flanges tau muab nrog pitting tiv taus uas yog ensuring zoo heev pitting corrosion tsis kam.

Cov qauv hluav taws xob ruaj khov tiv thaiv cov kua txob hauv cov tubrog nkoj. Duplex Flanges Txuas zoo txuas cov raj xa khoom sib txawv hauv cov kab ke thiab cuam tshuam rau cov kua dej lossis roj av. Cov qib kawm no muaj zog dua thiab tawg tawm tsam ntau dua li cov qib tsis muaj txiaj ntsig. Cov flanges no tseem muaj qhov du me me thiab tuaj yeem muab welded hauv qhov chaw siv cov txheej txheem txheem.

Txhua hom sib txawv muaj nws tus kheej zoo. Kev sib txawv qib ntawm chav hlau Duplex muaj cov khoom sib txawv thiab lub cev vim cov tshuaj sib txawv. ASTM A182 F60 flanges yog kev ua tau zoo, raug nqi ua tau zoo thiab lub neej ntev. Muaj ntau lub ntsej muag sib txawv hom kev sib koom ua ke flanges, tiaj tus ntsej muag flanges thiab tsa ntsej muag flanges.

DupleX Steel Flanges yog ua los ntawm chav yas thiab yog rau cov tsev neeg stainless hlau. Nws yog tsim los muab cov kev mob corrosion zoo dua, tshwj xeeb yog cov corroside kev ntxhov siab thiab muaj zog dua cov qauv tshuaj hlau hluav taws xob tsis muaj 304 lossis hlau stainless 316.

Chromium yog ib tug ferrite yav dhau los, uas txhais tau tias nws txhawb nqa cov qauv BCC qauv ntawm cov hlau. Nws kuj tseem nce oxidation tiv thaiv nyob rau ntawm qhov kub. Siab chromium kuj txhawb kev tsim ntawm intermetallic theem, uas yog detrimental rau Duplex stainless hlau thiab yuav tsum tau hais.

Cov hlau dua lub lag luam tau qhia rau kev ua lag luam raws li kev ua haujlwm cuam tshuam nrog cov teeb meem kev ntxhov siab uas tshwm sim los ntawm chlorine daws teeb meem. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov khoom siv dullex flange kuj ua rau cov flanges tsawg dua rau cov chlorine-ntxias pitting corrosion. Cov alloys no tsis tshua kim dua li cov hlau uas muaj menyuam yaus npib tsib xee.

Lub ntsej muag tsa sawv ntsug rau lub flange kom muaj ntau bolt qhov thiab kev sib txuas nto thaum lub caj dab welded clips cov yeeb nkab hauv qhov chaw. Cov ntawv thov yog roj thiab roj, roj av, petrochemical thiab lwm yam kev siv.

Dual-theem hlau pob tw-welded tsa lub ntsej muag lub ntsej muag flanges muab kev txiav kom zoo heev thiab kev hnav khaub ncaws nce thiab teeb tsa lub sijhawm.

Kev sib xyaw ntawm chromium, molybdenum thiab nitrogen muab kev tiv thaiv zoo los ntawm chloride kev ua haujlwm, uas ua rau lawv muaj txiaj ntsig zoo, muab cov ntaub ntawv sib tw kaw thiab qee qhov kev siv zaub mov noj.

ASTM A182 F53 flanges xa mus rau cov flanges ua los ntawm super duplex stainless hlau 2507 (uns unical forging txheej txheem.

Cov qauv zoo ntawm lub duplex yog cov khoom siv herracity-Austenite herdrid uas muaj lub zog zoo dua li 304 lossis 316. Offshore \ / cov ntawv thov seaterwater yog cov siv hom hlau no vim nws txoj kev ntxhov siab heev xeb tawg cov khoom. Yog li ntawd, duuplexes feem ntau pom nyob rau hauv qhov kev cia siab thiab siab lub nkoj thiab siab rau hauv cov nroog Port.
