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.
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.
Cov ANSI B16.5 Alloy Steel npleem mus rau Flange yog hom flange uas tso cai rau cov kav teb uas tso rau hauv flange thiab ua rau txuas rau hauv cov chaw kho kom zoo.
Duplex stainless hlau s31083 s32205 flanges nyiam muab cov zoo sib xws rau corrosion li Austenitic counterparts
Cov flanges tseem tuaj hauv B16.5, B16.47 thiab lwm yam qauv thiab qhov ntev. Lub alloy steel flange cov khoom tuaj yeem sib txawv raws li cov tshuaj lom neeg muaj pes tsawg leeg.
Hauv kev sib piv rau SS316, Ob 2205 tau raug sim nyob rau hauv kev ntxhov siab nyob rau hauv chav tsev kub. Cov txiaj ntsig qhia tau tias kev ua kom qaug zog yog ib zaug li ob zaug uas yog siab dua rau Duplex 2205.
Cov Flange Txuas feem ntau muaj cov teeb meem toastion, thiab cov to taub dej kom muaj nuj nqis yuav tsum tau tswj nyob rau hauv cov txheej txheem uas tau tso cai.
Duplex 2205 flanges ua ke cov kev ua tau zoo ntawm kev ntxhov siab corrosion tsis kam thiab lub zog siab ua los ntawm kev ua ib qho kev ua kom muaj txiaj ntsig ntawm cov roj ntsha ua tau zoo.
Alloy Steel Flanges tau ua nyob rau hauv txawv steel hlaus. Cov flanges sib txawv nyob rau hauv qhov ntev thiab hom. Muaj? nti txog 48 ntiv tes ntawm nasinal diaminal ntau thiab tsawg ntawm flanges.
220 flange muaj qhov zoo dav dav corrosion, siab tiv taus chloride kev ntxhov siab corrosion, thiab pitting thiab crevice corrosion.
Duplex 2205 Flanges yog tsim los ntawm Austenitic-Ferritic-ferritic-ferritic stainless hlau, uas tau tsim los kom muaj zog dua thiab corrosion tsis kam 300 series stainless hlau.
Duplex stainless hlau s31083 s32205 flanges txhim kho qhov tsis kam rau pitting corrosion
Qhov muab aluminium steel f21 flange yog ua tau zoo siv siv cov Nickel zoo tshaj plaws nrog kev pab ntawm kev siv cov txheej txheem tho kev.
Duplex 2205 Flanges muaj cov sulfide sulrosion corrosion, raws li cov chloride pitting thiab crevice corrosion resistant zoo dua rau 317l.
Tus Austenitic-Ferritic stainless variant nrog kev ntxhov siab ntau dua corrosion nrawm 304 thiab 316 Stainless thiab cuam tshuam lub zog.
Qeb no ntawm cov khoom siv suav nrog qib 2205, F51, F53, thiab F60. Duplex stainless tau nce nyob rau hauv cov nrov nyob rau hauv cov muaj npe nyob rau lub xyoo vim lawv cov neeg siv neeg zoo heev thiab cov neeg sib txawv yog qhov muaj ntau ntxiv.
Duplex stainless hlau s31083 s32205 flanges nrog pitting zoo thiab crevice corrosion tsis kam
Ob qho tib si Asme B16.5 thiab ASME B16.47 tau pom zoo cov yeeb nkab flanges ua los ntawm ib qho ntawm ob lub stuplex ntau.
Cov qib no tau zoo tshaj plaws rau kev pabcuam yooj yim flange kev sib txuas, tab sis me ntsis tsawg dua yog li thaum tsim ib tug qauv sib txuas. Hmoov zoo, kev ua haujlwm ntawm duplex rau hauv cov qauv sib zog thiab cov sib npaug ntawm cov qauv siv hluav taws xob ntau rau cov khoom siv me me hauv cov ntawv thov corbive.
Cov alloy F5 Flange yog siv rau kev hloov chaw ua kua thiab lwm yam dej rau ntau kev lag luam. Peb yog tsim los ntawm pab pawg ntawm tus kws tshaj lij Nim cov ntiv tes siv cov khoom siv raw zoo, cov cuab yeej niaj hnub no thiab ua ntej thev naus laus zis.
Flange kev sib txuas muaj lub zog zoo thiab kev sib khi, cov qauv yooj yim thiab tus nqi qis. Nws tuaj yeem raug rho tawm rov qab.
Flange feem ntau yog siv rau txuas kav dej lossis li qub, yog li nws tuaj yeem daws cov teeb meem saum toj no yooj yim.
Lub Flange Txuas hom feem ntau yog los nrog ob chav nyob, nrog gasket thiab qee qhov bolts & ceev txuas sib txuas. (Cov kav dej ua ntej yog welded ntawm cov flanges, tom qab ntawd li qub thiab lwm yam khoom siv tuaj yeem ntsia tau ntawm cov flanges.)
Thaum txuas cov ntu no, tso gasket nyob hauv nruab nrab ntawm ob flanges, ces zawm cov flange screws, yog li ob yuav txuas ua ke kom nruj.
Duplex¡¯ hwm hwm cov neeg kho tshuab thiab tshuaj lom neeg yog me ntsis offset los ntawm nws cov kev nyuaj hauv kev muaj txiaj ntsig.
Stainless, Duplex, Tshwj xeeb Alloy, Monel, Hastelloy, Nitronic & Carbon Steel - Zhengzhou Huitong Pipeline Equipment Co., Ltd.
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.
Nyob rau hauv rooj plaub kev saib xyuas pipeline, peb tuaj yeem tshem tawm cov screws rau ntawm flange, nqa tawm cov kav dej sib raug lossis cov li qub. Lub caij no los hloov cov kav dej tshiab thiab li qub.
Kev sib txuas ntawm ob lub pas dej tuaj yeem muab ncaj qha welded ua ke, tab sis nws yog qhov nyuaj rau txuas ua ke yam tsis muaj vuam. Thaum qhov kev sib txuas muaj teeb meem, nws yuav nyuaj rau kev kho. Cov teeb meem tib yam kuj tau tshwm sim ntawm cov yeeb nkab thiab valve txuas.
Cov qauv zoo nkauj ntawm duplex yog ib tug ferrite-Austenite-Austenite-Austenite-Austenitic thiab 316.
