DupleX Steel Flanges

Duplex flanges muaj ib yam khoom siv hu ua Duplex. Cov khoom siv muaj ob qho tib si ferritic thiab ustenitic micrtructures hauv metallurgy. Muaj cov qhab nia sib txawv ntawm lub duplex nyob ntawm cov khoom muaj pes tsawg leeg. Duplex stainless hlau flanges muaj qhov zoo tshaj plaws ferritic thiab Austenitic cov khoom. Lawv tau siv los hloov cov khoom hloov rau cov khoom siv siab kim hauv ntau daim ntawv thov kev 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.

2205 flanges muaj kev tiv thaiv zoo heev rau pitting thiab crevice corrosion, ua tau zoo nyob rau hauv feem ntau corrosive ib puag ncig, thiab muaj kev weldability zoo. Cov lus qhia tshwj xeeb no ob theem steel steel s31803 feem ntau kub hnyiab s31803 feem ntau yog ua rau muaj qhov kub ntawm 300 degrees raug rau 475 degrees Celsius.

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.

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.

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.

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.

Duplex 2205 thiab super duplex 2507 stainless hlau taub qab weltealed tawm lub zog ntawm cov hlau tsis muaj txiaj ntsig xws li 304 thiab 316 Stainless Hlau Weld Flanges. Vim tias qhov no, Duplex 2205 thiab super ruplex 2507 steel qeb siv rau pob tw weld flange yog qib ntau dua ntawm ob.

Duplex Steel Werkstoff tsis yog 1.4462 xov tsis tau siv hauv qab -50¡Ãc raws li nws yuav ua rau tus ductile kom tawg. Duplex uns S32205 Orifice Flange muaj lub zog tensile ntawm 1,16,000 psi 800 MPa. Whereas lub ruplex saf 2205 socket weld flang muaj cov txiaj ntsig muaj zog ntawm 80,000 psi 550 MPa. Lub 2205 Duplex Taubteb Weld Flange yog qhov tsis muaj cuam tshuam los ntawm kev xav thiab zam cov nag los nag.

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 Steel Flanges feem ntau siv rau kev ua haujlwm hnyav welded Cheebtsam. Peb tsim cov flanges no siv cov khoom siv raw zoo. Peb cov neeg muas zaub ntseeg peb hauv qhov zoo ntawm peb cov khoom raws li peb txuas ntxiv mus txhim kho peb cov thev naus laus zis thiab muab cov khoom ua kom ncaj ncees thiab cov kev pabcuam.

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.

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.

Taub qab vuam flanges yog drilled (machined), thiab phab ntsa tuab ntawm flange yog tib qho loj li cov yeeb nkab sib xyaw. Lub sib dua lub raj, cov cheeb tsam loj dua, thiab hloov kho lub raj, cov kab me me. Peb cov hauv pob tw weld flanges, taub qab weld flanges feem ntau yog siv rau kev kub siab, tsawg kub lossis kub.

Super Duplex 2507, yog lub duplex stainless hlau tshwj xeeb tshaj yog haum rau ib puag ncig xws li sov chlorinated seawater thiab acidic chlorinated media. Nws muaj cov khoom zoo sib xws rau Duplex 2205 tab sis yog kev corrosion ntau dua thiab ua tau zoo nyob rau hauv ib puag ncig corrosive ib puag ncig.

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.

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.

Duplex thiab Super Dupluam flanges yog qhov zoo tagnrho rau kev nthuav dav zoo, thiab ntsuas kub thiab nws qhov tseem ceeb yog tias nws tsim nyog rau cov ntawv thov siab.

Rau ntau cov ntawv thov uas 300 series stainless hlau yog qhov raug rau cov chloride kev ntxhov siab tawg, 2205 duplex stainless hlau yog qhov kev daws teeb meem zoo. Kev ntxhov siab corrosion tawg tshwm sim thaum stainless hlau yog raug rau tensile muaj kev ntxhov siab thaum sib cuag nrog cov kev daws teeb meem uas muaj chlorides. Kev kub siab dua kub kuj nce ntxiv qhov kev ua kom muaj kev phom sij ntawm cov hlau tsis muaj mob corrosion.

Duplex 2205 yog nitrogen txhim kho cov yas stainless hlau tsim los daws cov teeb meem corrosion nrog 300 series cov hlau stainless. "Duplex" piav qhia txog tsev neeg ntawm stainless cov hlau uas tsis yog Austenitic (xws li 304 stainless hlau) tsis yog 430 stainless hlau). Tus qauv ntawm 2205 duplex stainless hlau muaj cov pas dej ntawm Austenite ib puag ncig los ntawm kev txuas ntxiv ferrite theem. Nyob rau hauv anealed mob, 2205 muaj kwv yees li 40-50% ferrite. 2205 feem ntau raug xa mus ua cov qib haujlwm ua haujlwm thiab yog cov dav dav siv dav dav hauv tsev neeg lub cev tsis muaj roj stuple.

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.

Cov flanges tau nyob sab hauv kom phim rau sab hauv lub taub ntawm cov yeeb nkab kom ntseeg tau tias tsis muaj kev ntxhov siab ntawm kev sib koom ua ke. Lub caj dab tapered muab cov hlau tuab ntawm cov hlau flange ntawm cov pob txha flange, thaum lub caj dab tapers rau pob yeeb thiab mus rau pob tw tiv thaiv cov yeeb nkab. Tus qauv no yuav pab hloov kev ntxhov siab ntawm Flange rau cov yeeb nkab rau cov yeeb nkab thiab txo cov kev ntxhov siab cov kev sib txuas hauv qab ntawm cov flange kev txuas.

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.

Duplex 2205, tsis yog S32205, yog cov khoom siv stainless hlau uas muaj cov microstructure muaj sib npaug muaj sib npaug ntawm cov ferrite thiab austenite. Cov qib no yog hom nrov tshaj plaws, thiab ob hom khoom siv ob-theem no yog qhov tseem ceeb tshaj 316 stainless hlau nyob rau hauv cov nqe lus muaj zog thiab corrosion tsis kam.

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.

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.
