Lub chav dav hlau chav rau muaj ob zaug lub zog ntawm feem ntau Austenitic thiab stainless hlau qib. Cov hlau no tau sib piv ntau dua corrosion tiv taus ntau qib. / / Nws kuj muaj cov khoom phem uas muaj zog zoo li cov khoom lag luam thermal thiab qis dua cov hlau antenatic. Cov txiaj ntsig muaj txiaj ntsig yog li ob zaug ntawm kev siv cov hlau tsis muaj txiaj ntsig, tso cai rau cov neeg tsim qauv kom txuag tau qhov hnyav thiab ua piv rau Alloy 316L lossis Alloy 317L.

2205 lub fasteners tau siv dav hauv cov ntawv thov uas yuav tsum tau corrosion tsis kam thiab lub zog. Muaj zoo corrosion tsis kam; ntau dua li lwm cov qib. Nws tshem tawm cov hom corrosion hauv cheeb tsam xws li kev txhim kho corrosion, pitting corrosion thiab crevice corrosion. Duplex 2205 Bolts yog qhov zoo rau ib puag ncig muaj cov tshuaj chlorides thiab roj extraction los ntawm cov hmoov av qaub, thiab cov tshuaj ntxiv, thiab tshuaj chloride cov txheej txheem.

Lub 2205 tau tsim los muab kev zoo heev ntawm ultrasonic muaj. Kev tswj hwm ntawm kev sib xyaw thiab cov khoom sib xyaw ua ke tsim kho cov cuab yeej kev hnav thiab siv cov cuab yeej ntau dua thiab cov nqi qis dua.

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.

Super Duplex 2507 (F53 \ / 1.4410) muaj kev tiv thaiv corrosion, thiab lwm qhov chaw corrosion, nrog rau cov croundy-corrosion, thiab lwm qhov chaw corroside zoo tshaj plaws, nrog rau qhov ntsuas kub tseem ceeb tshaj 50¡Ãc.

Tsis zoo li cov kev siv Austenic 300 series stainless hlau, duplex stainless hlau feem ntau muaj exagless cov khoom. Duplex raj tso tshuaj pom zoo kom siv tsuas cov alloy no raws li nws ua ke cov khoom siv los ua cov txiaj ntsig zoo.

Lub siab muaj peev xwm ntawm cov flanges kuj tseem tuaj yeem qhia hauv cov lej siab. Lub ASTM A182 F53 Un Un unical S32750 Flange hom tuaj hauv cov lej siab los ntawm PN6 los ntawm PN64.

Duplex stainless hlau stainless hlau (DSS) yog nthuav nrog cov qauv ntawm ob ntu (| thiab muaj cov yam ntxwv ntawm ob qho tib si ferritic thiab antenitic steel. Nws muaj zoo corrosion tsis kam thiab muaj zog siab. Nws yog txuam nrog 18% -28% cr thiab 3% -10% ni hauv cov kab mob qis xws li mooy, CU, TI thiab N, thiab lwm yam.

Duplex Stainless hlau yog Fe-Ni-Cur alloys muaj ntawm Ferritic-Austenitic Microstructure ntawm chav tsev kub. Cov hlau no feem ntau muaj cov kev sib txuas tau zoo ntawm kev ua kom muaj txiaj ntsig thiab theem ferritic. Duplex stainless hlau nthuav tawm kev muaj zog dua thiab zoo dua weldability tshaj li ferritic steel (Nilsson, 1992). Lawv muaj lub zog dua thiab cov corrosion zoo dua li usteneric stainless hlau (Atamert thiab huab tais, 1992). Lawv cov kev ua tau zoo engineering tau coj mus rau ntau cov ntawv thov nce, feem ntau yog nyob rau hauv cov chaw muaj kev sib raug zoo xws li sour roj pipelines thiab tshuaj lom neeg cov tshuaj tiv thaiv.

Qhov no alloy yog tshwj xeeb tshaj yog pab tau nyob rau hauv cov -50¡ÃF \ / + 600Ãf kub. Rau cov ntawv thov sab nraum qhov kub thiab txias no, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog siv hauv Welded qauv.

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

Duplex 2205 Bolts (en 1.4462) yog tsim los ntawm cov av tsis muaj zog thiab corrosion tsis kam li 300 series stainless hlau. Nws pab cov neeg siv kom tsis txhob muaj kev ntxhov siab corrosion uas ib txwm tau pom nrog kev ntxhov siab ntawm kev ntxhov siab nrog nws cov kev ua kom muaj peev xwm ua tau zoo.

Qhov no yog qhov laj thawj tseem ceeb vim li cas super denplex flanges nco ntsoov cov kev txhim kho tensile lub zog tshaj ferritic thiab Austenitic style.

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.
A789 unc unic s31803 thiab unspes ob qib ntawm ob chav stainless hlau uas tau siv dav hauv ntau cov ntawv thov. Cov txiv neej duplex s31803 Seamless kav yog paub rau lawv cov txiv neej ua hauj lwm zoo, muaj lub zog siab, thiab weldability thiab zoo weldability. A789 yog ib qho tshwj xeeb uas tau them seamless thiab welded tub ua los ntawm duplex steel stainless hlau.
Ib Flange yog ib qho kev tawm tsam, daim di ncauj lossis sab nraud, tog twg los sab nraud lossis sab hauv, uas yog cov nqaj hlau xws li ib tug t-nqaj); Rau cov ntawv yooj yim tau yooj yim \ / hloov ntawm kev sib cuag nrog lwm yam khoom (raws li flange thaum kawg ntawm cov yeeb nkab, chav dej lub tog raj kheej, lossis ntawm lub ntsej muag lub koob yees duab); Los yog rau kev ruaj khov thiab taw qhia kev txav ntawm lub tshuab lossis nws cov ntu (raws li sab hauv flange ntawm tsheb ciav hlau lossis lub log los ntawm kev khiav tawm ntawm cov ciav hlau). Lo lus "Flange" kuj yog siv rau hom cuab yeej siv los ua cov flanges.

A182 gr. F51 \ / S31803 cov khoom siv yog ib qho duplex stainless hlau, uas muaj kwv yees li 50% ferrite thiab 50% austenite.

Duplex 2205 bolts muaj tus ductile hloov ntawm ntawm -50¡Ãc thiab kuj tau tsoo ntawm 300-1000,000 Raug rau saum 300 yuav tsis tsuas yog ua rau embrittlement ntawm 2205 bolts, tab sis kuj yuav txo kom corrosion tsis kam.

Nws tseem muaj cov khoom phem uas muaj zog loj hlob zoo li qis dua thermal nthuav dav thiab siab dua thermal conductivity tshaj li cov hlau ua kom zoo nkauj. Cov txiaj ntsig muaj txiaj ntsig yog li ob zaug ntawm kev siv cov hlau tsis muaj txiaj ntsig, tso cai rau cov neeg tsim qauv kom txuag tau qhov hnyav thiab ua piv rau Alloy 316L lossis Alloy 317L.

Vim yog cov khoom siv tshuab hluav taws xob zoo thiab cov kws kho tshuab ntawm super duplex, qhov zoo tshaj ntawm super duplex lub zog tuaj yeem ntsib cov roj ntau ntawm cov roj, roj thiab marine kev lag luam.
