Duplex Stainless Hlau S31083 S32205 Flanges ntawm Sevices ntawm High Corrosion - Zhengzhou Huitong Pipeline Equipment Co., Ltd.

Super Duplex und s32760 round pas nrig muaj ntau yam khoom thiab cov khoom vim muaj cov khoom siv tshuaj lom neeg. Vim muaj cov yam ntxwv thiab cov khoom, cov thawj duplex uns s32760 puag ncig yog siv nyob rau hauv ntau cov ntawv thov kev lag luam.

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.

Duplex stainless hlau muaj microstructure uas yog 50% Ferritic thiab 50% Austenic. Cov muaj pes tsawg no muab lawv lub zog zoo dua li cov hlau ferritic lossis austenitic steels. Cov ntsiab lus ntxiv txog cov ntsiab lus no tau muab hauv qab no (saib ASTM A790 kav).

Alloy 2507 muaj 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Qhov siab molybdenum, chromium thiab nitrogen cov ntsiab lus ua rau chloride nres thiab crevice corrosion nres thiab crevice corrosion nres rau chloride kev ntxhov siab corrosion.
ASTM A240 Hom 2205 Phaj yog lub Duplex phaj yog siv ntau yam kev lag luam xws li kev ua yeeb yam, roj thiab roj kev tshawb nrhiav, thiab marine engineering. Sa 240 gr 2205 daim ntawv yog tsim los ntawm qib 220) stainless hlau, uas yog kev sib xyaw ntawm ferritic thiab ustenitic steel.
Lwm qhov laj thawj yog vim li cas vim li cas vim li cas vim li cas vim li cas los vim li cas, Flyded Flange yog vim tias lawv tso saib cov kev ntxhov siab zoo heev corrosion (sCC) tsis kam. Duplex SS Flanges muaj cov kev qhia tshwj xeeb uas muaj qee cov ntsiab lus xws li cov qauv, hom, tsim qauv, tsim qauv thiab ntau ntxiv. Txawm tias Duplex cov yeeb nkab flanges muaj cov kev ntsuas siab zoo li chav kawm zoo li cov hauv siab siab thiab tseem ceeb ntawm qhov no txawv. Lub flange yog sab nraud lossis sab hauv nruab nrab ntawm ob lub kav dej uas muab ib txoj kev txuas txuas, li qub, twj thiab lwm yam khoom siv rau tag nrho cov kav dej piping. S31803 tseem siv rau hauv marine raws li roj & roj extraction thiab kev ua siv siv 2205 flanges hauv chloride thiab hydrogen sulfide ib cheeb tsam.

Lub siab Molybdenum Superaustenitic nrog kev ua tau zoo rau chloride pitting, crevice corrosion thiab kev nyuaj siab corrosion tawg. Haum rau kev siv hauv plawv hniav cov zaub ntsuab, nroj tsuag dej kom cua sov thiab cov khoom siv txheej txheem tshuaj lom neeg.

Muaj cov cheebtsam ntawm ob 2205 lub fasteners muaj xws li studs, teeb screws, bolts, tshuab ntxhua khaub ncaws thiab ceev. Thaum twg koj tshwj xeeb txiav txim siab Duplex Stainless Hlau 2205 Gaskets, nws tuaj yeem yog cov txiaj ntsig zoo rau ntau hom kev lag luam tseem ceeb feem ntau pom muaj nyob hauv cov chaw hnyav. Yuav luag txhua hom ntawm 2205 stainless hlau gaskets yuav muab cov kev pabcuam ib txwm muaj rau cov ntawv thov sib txawv lossis dej hiav txwv thiab petrochemical, twj, thiab lwm yam.

Qee cov hlau ua kuj muaj cov alloy hais xws li mo, CU, Ti thiab N, thiab lwm yam thiab muaj zog thiab zoo dua intergranular cuam tshuam thiab weldability.

Piv nrog ustenitic steel hlau, f51 tus txheej txheem duplex muaj ob zaug lub zog, thiab piv nrog 316L thiab 317L, tus tsim qauv tuaj yeem txo nws qhov hnyav.

Nws tseem yog tshwj xeeb tsis kam rau chloride SCC. Flanges tau muab nrog pitting tiv taus uas yog ensuring zoo heev pitting corrosion tsis kam.

Hauv S31803, kwv yees li ib nrab ntawm cov ferrite nplej hloov mus rau hauv Austenite nplej ("Islands tuaj") raws li cov khoom txias mus rau chav sov. Qhov tshwm sim yog microstructure ntawm kwv yees li 50% austenite thiab 50% ferrite.

Lub ASTM A182 F51 flanges xa mus rau tus qauv lossis tsis yog cov qauv hlua tsim ua raws li ANTM A182 qib F51, uas yog tsim qauv nrog UNSONE S31803.

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.

Super Duplex 2507 Txiv Ntseej muaj cov khoom siv tau zoo heev

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.

Nws yog dav siv nyob rau hauv cov roj pov thiab roj kev tshawb nrhiav \ / ntau lawm thiab hauv kev hloov cua sov hauv petrochemical \ / tshuaj lom neeg.

Cov qauv zoo nkauj ntawm duplex yog ib tug ferrite-Austenite-Austenite-Austenite-Austenitic thiab 316.

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.

Lub ntsiab lus d32760 daim ntawv ua tau zoo ntawm sub-xoom qhov kub, mus rau -50¡Ãc ntau, thaum ua tau zoo ntawm qhov kub huab cua sov.

Duplex 2205 Fasteners yog tsim los ntawm cov nqi-ua tau zoo, ntev-ntev thiab corrosion-resistant steel. Cov qib ntawm cov hlau siv los ua cov fasteners tuaj yeem yog ferritic, ustenitic lossis dual theem. Duplex cov ntaub ntawv muaj lub zog zoo ntawm ferritic steels thiab corrosion-resistant zoo ntawm Austenitic steels.

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.

Duplex 2507 feem ntau yog siv nyob rau hauv cov cuab yeej tshuaj ntxuav, tshuaj lom neeg siab cov hlab ntsha, piping thiab tshav kub hloov thiab cov ntawv thov cua sov thiab cov khoom siv ua kom sov thiab cua sov.

Duplex-qib stainless hlau alloys muaj ferritic \ / Austenitic cov khoom, muab cov ntaub ntawv zoo dua lub zog thiab qhov zoo heev rau oxidation.

ASTM A1082 Specification Alloy S31803 muaj peev xwm ua kom muaj zog dua li lwm cov kev siv hluav taws xob zoo dua li qub 316. Vim tias nws siv cov roj ntsha uas muaj ntau yam nyob hauv ib puag ncig muaj cov xov xwm corrosive.

Muab cov kev lag luam kev txhim kho cov tshuaj tsis muaj zog ntawm cov tshuaj tsis muaj zog, zoo li chloride pitting thiab crevice corrosion superior rau 317l. 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, muab cov ntaub ntawv teev cov khoom noj.

Duplex 2205 stainless hlau (Ferritic thiab Austenitic thiab Austenitic) tau siv dav hauv cov ntawv thov corrosion tsis kam thiab lub zog. Qib S31803 hloov kho cov hlau ob peb zaug los ua cov unsist undu S32205, uas tau lees paub thaum xyoo 1996.
