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.

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.

Austenitic-ferritic stainless hlau variants muaj ntau dua rau kev ntxhov siab corrosion tawg, tab sis qis zog dua li Austenitic 304 thiab 316 Stainless hlau. Cov ntaub ntawv xws li tau qhab nia 2205, F51, F53 thiab F60. Duplex stainless hlau tau loj nyob rau hauv cov npe nrov tau ntau xyoo vim yog lawv cov khoom siv hluav taws xob zoo nkauj, tshwj xeeb yog muab cov nqi ntau dua, tus nqi sib txawv yog tam sim no me me.

220 flange muaj qhov zoo dav dav corrosion, siab tiv taus chloride kev ntxhov siab corrosion, thiab pitting thiab crevice corrosion.

Ob chav pob tw weld flanges yog qhov zoo tshaj plaws rau cov ntawv thov kev muaj kev phom sij. Taub qab Weld Flanges tau yooj yim pom los ntawm lawv lub caj dab ntev.

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.

Piv rau cov qib zoo sib xws thiab cov qib qis, tus nqi Super Roge thiab, vim lub zog zoo dua thiab, muaj corrosion tsis kam.

Vim yog cov alloy zoo heev tiv thaiv hydrochloric acid, Super Duplex 2507 flanges tuaj yeem siv rau hauv kev lag luam tshuaj lom neeg. Lwm qhov teeb meem uas muaj nrog cov hlau alloys yog tias lawv nyiam corrode thaum vuam. Thaum cov alloy yog welded, qhov ntsuas kub yog siab, thiab ntau dhau carbon atoms yog precipitated los tsim carbide precipitates.

DupleX Steel Flanges yog cov nyom tawv uas tseem yog cov tiv taus corrosion kuj yog resistant. Lub microstructure ntawm cov hlau no muaj kev sib xyaw ntawm ferrite thiab austenite kaujs. Yog li ntawd, lawv muaj cov yam ntxwv ntawm ob qho tib si ferritic thiab anustenitic stainless hlau.

Cov roj duplex no unsllex steel uns s32760 flanges yog thev naus laus zis siab siv cov ntaub ntawv tshaj tawm cov kws tshaj lij. Lawv muaj cov yam ntxwv zoo tshaj plaws xws li kev tawm tsam yas ntxiv, hnav tsis kam, chipping tsis kam, thiab zoo machinability.

A182 F53 2507 Floffe tshwj xeeb muaj zoo dua thermal conductivity thiab qis coefficient ntawm thermal expansion

Raws li kev dig muag hauv nruab nrab hlau, Duplex dig muag tsa lub ntsej muag muaj zog thiab ob zaug rau cov neeg siv hluav taws xob piv rau cov qauv hlau stainless hlau ASTM 316L.

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.

ASME B16.5 DUPLEX Steel Forged Flanges muaj nyob rau hauv ntau thiab tsawg los ntawm 1 \ / 8 "txog 24". Nyob ntawm qhov loj me, flanges muaj nyob hauv cov chav kawm siab sib txawv. Chav Kawm 150 DuPlex yeeb nkab flanges yog qhov qis tshaj plaws ntawm chav kawm txog 2500.

S31803 tau muab ntxiv los ntawm S32205 (F60) uas muaj qhov tsawg dua n, mo, ni thiab cr xij uas lav tau corrosion zoo dua.

¤ ¤ 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).

Cov alloy txawv no yog siv hauv cov roj thiab roj kev tshawb nrhiav thiab tseem siv hauv kev lag luam ua lag luam. Cov cuab yeej ua lag luam tshaj plaws siv Duplex 2205. Kuj tseem siv los ntawm kev lag luam cia thiab tsheb thauj mus los. Pulp thiab cov ntawv luam tawm, tso tsheb hlau luam thiab ntawv ua kua thiab ntawv tshuab kuj siv duplex 2205. Nws yog qhov zoo rau kev siv hauv ib puag ncig marine.

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.

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.

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

Qhov zoo dua ntawm cov qauv dual Qhov kev pabcuam kub ntawm 2205 duplex stainless hlau yuav tsum tau txwv rau hauv qab 600¡Ãf. Ntev tau raug rau qhov kub siab tuaj yeem ua 2205 stainless hlau nkig.

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.

Kev siv cov yas thiab super duplex stainless hlau yuav tsum tau txwv rau hauv qab 570¡Ãf, raws li ntev ntev tau ua kom cov khoom nkig tuaj yeem ua rau cov khoom tawg tuaj yeem ua cov khoom tawg tuaj yeem ua cov khoom nkig.

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.

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.

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.

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.

Duplex cov hlau stainless yeeb nkab muag khoom pom zoo cov kev ua haujlwm rau ntau yam haujlwm ntawm kev ua haujlwm tau zoo li cov haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm lub cev, I.E. Los ntawm hom 304 lossis 316 txog 6% Molybdenum stainless hlau.

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.

ASTM A182 Duplex Stainless Hlau Flanges txhim kho kev muaj formability thiab weldbility

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.
