ASTM A182 Duplex Stainless Hlau Flanges rau cov roj thiab roj thiab lwm yam kev ua haujlwm luam tshuab

Nws cuam tshuam lub zog lossis hardness zog tau txais los ntawm Ferritic sab ua rau 2507 stainless hlau hloov bar haum rau kev siv nrog rau kev tsim kho thiab ntau dua.

Lwm qhov laj thawj rau cov khoom siv zoo ntawm ob lub pob tsuas muaj peev xwm sib xyaw tab sis ferritic microstriticure tam sim no hauv cov alloy.

Cov yeeb nkab roj dulex tau txais nws lub npe los ntawm dual xwm tam sim no nyob rau hauv microstructure ntawm alloy. Duplex stainless hlau seamless cov yeeb nkab muaj cov yam ntxwv zoo kho thiab tuaj yeem siv rau hauv ib qho xwm txheej welded. Suav hais tias yog zoo dua hauv kev sib piv rau Austison alloys toys ASTM A312 Tp3Tlex yeeb muaj ntau dua zoo tiv thaiv kom xeb.

Siab chromium, molybdenum thiab nitrogen cov ntsiab lus cuam tshuam nrog pitting tsis zoo rau cov medtenatent thiab corrosive corrosive conduction, thiab tseem ceeb pitting txias rau tag nrho cov xov xwm, thiab tseem ceeb pitting txias rau saum 50¡Ãc.

Alloy 2205 muab pitting thiab crevice corrosion tsis kam zoo dua rau 316L lossis 317l Austenitic Stainless hlau raj hauv yuav luag txhua corrosive media. Nws tseem muaj cov kev ua kom muaj zog thiab cov nyom ntawm cov khoom muaj zog nrog rau qis dua thermal nthuav dav thiab siab dua thermal conductivity tshaj li Austenitic.

Raws li cov kws tshaj lij hauv kev ua haujlwm ntawm lub fasteners, peb pom tau tias cov ntaub ntawv cua sov, kiv cua, cov khoom siv roj hmab thiab nias yob. Ntawm ht yeeb koj tuaj yeem pom cov roj duplex hwm hauv cov txiaj ntsig zoo.

Qhov no alloy tiv taus chloride ib puag ncig thiab sulfide kev nyuaj siab corrosion. Nws tseem yog kwv yees ob npaug lub zog ntawm cov qauv ntawm cov hlau tsis huv.

Super Duplex stainless hlau yog paub kom muaj kev ntxhov siab zoo dua corrosion, tawg ua kom tsis taus thiab cov kws kho tshuab ntau dua li lwm hom hlau.

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.

Cov ntaub ntawv siv los tsim cov fasteners yog ntawm sab saum toj zoo thiab tus qauv, yog li nce lub zog ntawm cov khoom kawg rau cov kev siv tawm tsis zoo rau cov kev siv tawm tsis zoo.

Duplex 2507 yog super duplex stainless hlau muaj 25% chromium, 4% molybdenum thiab 7% npib tsib xee. Cov alloy no tsim rau cov ntawv thov uas yuav tsum tau muaj lub zog zoo thiab corrosion tsis kam.

Ob lub chav hlau obleoys muaj cov khoom ntawm cov hlau tsis muaj tshuaj thiab thiab cov hlau ferritic stainless. Qhov no yog vim tias lawv tau muaj yuav luag sib npaug sib npaug ntawm ob lub roj teeb tsa (austenite thiab ferrite) hauv anealed mob.

Super Duplex 2507 Txiv Ntseej rau cov tshuaj lom neeg petrochemical thiab dej hiav txwv

ASTM A479 Duplex Stainless Hlau 1.4462 punc resistant uas yog qhov tseem ceeb hauv cov dej kub, cov nroj tsuag brewing, desalination nroj tsuag thiab ua nroj tsuag. Yog li no, Astm A479 Duplex Stainless Hlau Unfless Hlau Unfless Hlau Unfless Hlau uncers ua rau cov khoom ntawm ferritic thiab austenitic alloys.
S31803 Cov Ntawv Tshaj Tawm Tshaj Tawm Tshaj Tawm Pom Cov Khoom ntawm Ferritic thiab Austenitic Stainless Hlau. Cov fasteners nthuav tawm zoo heev rau cov crevice corrosion, kev nyuaj siab corrosion tawg thiab pitting corrosion nyob rau hauv ib puag ncig hnyav. Tsis tas li ntawd, cov no yog qhov zoo tshaj plaws rau chloride thiab sulfide kev nyuaj siab corrosion.
Txhawm rau kom xa cov raj xa dej, nws yog ib qho tsim nyog los tshem cov hose ncaj hauv cov raj xa dej. Thaum siv ntau lub raj xa dej, ntau yam kav dej yuav tsum tau siv. Thaum twg cov raj xa dej siv, lub luj tshib yuav tsum tau siv los hloov qhov loj ntawm cov raj xa dej. Thaum bifurcating, peb-txoj kev xaim cov flange kev sib txuas siv thaum lub raj xa hluav taws xob thiab kev sib txuas txias thiab kev sib tw txias thiab kev sib koom ua ke txias. , Hauv kev sib txuas ntawm ntau cov twj paj nruag, kuj tseem muaj cov txuas txuas thiab ntsaws ntawm cov twj paj nruag theem.

Kev siv ntawm Duplex 2507 yuav tsum tau txwv rau cov ntawv thov hauv qab 600¡Ã f (316¡Ã c). Kev nce qib ncua kev kub ntxhov tuaj yeem txo ob qho tib si cov tawv thiab corrosion tsis kam ntawm alloy 2507.

Unric unicial s32750 lossis din w.nr. 1.4410, Duplex 2507 yog super duplex stainless hlau consutaining 25% oboly, xws li cov txheej txheem tshuaj lom neeg, petrochemical thiab seagatermenut.

Vim yog lub zog tiv thaiv kev siv tshuaj lom neeg suav nrog cov kua qaub, hauv paus doss thiab neutx tsis yog qhov zoo tshaj plaws ntxiv rau cov kev lag luam no.

Ib txoj kev sib koom ua ke flanged yog tsim ntawm peb cais thiab ywj siab yog tias muaj kev sib cuam tshuam; Cov flanges, lub gaskets, thiab cov bolting; Uas tau sib sau los ntawm kev cuam tshuam lwm tus cuam tshuam, fitter. Cov kev tswj tshwj xeeb yuav tsum muaj nyob rau hauv kev xaiv thiab kev xaiv ntawm tag nrho cov muaj cov ntsiab lus kom muaj kev sib koom ua ke, uas tau siv tau xau nruj.

Super Duplex steel muaj txiaj ntsig raws li nws counterpart ¨c nws tau txo qis cov nqi thaum piv nrog cov qhab nia sib piv thiab Ferritic.

Qib 2205 yog cov feem ntau siv siv dav hlau steel hlau. Fittings ntawm cov ntawv kawm qib kawm no vim yog ob qho tib si lawv zoo heev corrosion tsis kam raws li lawv lub zog siab.

Sib nrug ntawm no sa 182 F53 HEX Hex kuj tseem muaj kev ntxhov siab thiab chloride kev ntxhov siab muaj feem cuam tshuam nrog kev tawm tsam kev tawm tsam nrog kev tawm tsam cov pob zeb. ASTM A182 F53 Outlets muaj cov khoom zoo zoo rau cov neeg siv khoom kom haum. Raws li tau muaj los ntawm Tshuag, peb kuj yuav siv cov astm A182 f53 qhov loj me hauv qhov loj me thiab cov duab raws li cov kev xav tau ntawm kev tsim qauv thiab qhov ntev. Qhov no yog vim lub siab Molybdenum, chromium.

Duplex 2205 stainless hlau phaj muaj zoo corrosion ua hauj lwm zoo, ntau dua li cov hom qib corrosion xws li intergranular, pitting thiab crevice.

Lub DSPlex qauv muab 2507 nrog tshwj xeeb tsis kam rau pitting thiab chloride kev ntxhov siab corrosion.
