Duplex 2205 Flanges yog tsim los ntawm Austenitic-Ferritic stainless hlau thiab yog tsim los muab lub zog siab dua thiab corrosion tsis kam li 300 series stainless hlau. Nws pab cov neeg siv tsis txhob muaj kev ntxhov siab rau kev ntxhov siab rau 316 thiab 317.

Lub oxidation tiv thaiv cov theem ob steel s31803 zoo li muaj nkig ntawm qhov kub ntawm 300 degrite tom qab sib kis ntawm 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 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.

Duplex 2205 Taub Hau Weld Flanges (Flar Flanges (yooj yim pom kev ntawm lub raj ntev taper, maj mam ncua los ntawm cov yeeb nkab lossis haum rau ntawm phab ntsa tuab. Ntev taper cov hubs muab cov khoom tseem ceeb kom siv nyob rau ntau yam kev siv nrog kev kub siab, sub-xoom thiab kub. Kev hloov pauv ntawm Flange tuab heev rau cov yeeb nkab tuab rau cov yeeb nkab lossis cov phab ntsa tuab yog qhov kev nthuav dav los ntawm kev nthuav dav los ntawm linear nthuav lossis lwm yam kev sib txawv.

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.

Duplex 2205 tau raug sim nyob rau hauv kev cuam tshuam los ntawm chav sov ntawm chav sov piv rau SS316. Cov txiaj ntsig qhia tau hais tias Duplex 2205 muaj kwv yees li ob zaug ntawm kev qaug zog hloov \ / paib lub zog.

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.

Kev sib xyaw ua ke ntawm chromium, molybdenum thiab nitrogen muab kev tiv thaiv txiv neej zoo nkauj, uas ua rau lawv muaj txiaj ntsig zoo, cov tshuaj ua kom dawb, kaw cov ntawv thov ua zaub mov noj thiab qee qhov kev siv zaub mov noj. Txawm hais tias nws yog ib qho tseem ceeb kom nco ntsoov tias pitting corrosion tuaj yeem yog qhov teeb meem hauv cov tshuaj chloride thaum oxidizing xov xwm tam sim no. Nyob rau hauv cov kev mob no, lub passive (tiv thaiv (tiv thaiv) txheej ntawm lub duplex 2205 cov khoom siv yuav raug puas thiab pittingcompized yuav tshwm sim.

Peb muab cov flanges ua tiav, suav nrog khau khiab hauv qab, cov flanges dig muag, tso tawm Weld Flanges, Reducer Flanges, thiab ntau dua. Vim muaj ntau yam ntawm cov neeg siv khoom, peb muab cov roj dulex steel uns s32750 flanges nyob rau ntau qhov ntau thiab tsawg.

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.

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.

S32205 yog ob theem ob theem steel nrog ze li ntawm cov sib npaug ntawm cov ooustenite thiab ferrite hauv nws cov tshuaj lom neeg muaj pes tsawg leeg. Qhov kev sib xyaw ua ke no ua rau muaj zog tshaj dua cov qauv siv tshuaj tiv thaiv cov hlau. Lub khawm ob lub flatx s31803 lub nplhaib haum rau Flange yog cov carbon qis version thiab yog cov tshuaj tiv thaiv kab mob.
