ASTM A928 Chav Kawm 1 Duplex Stainless Yeeb

S32205 Phaj Superior rau 316L lossis 317l Austenitic Stainless hlau nyob rau yuav luag txhua cov xov xwm corrosive

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.

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.

Cov khoom siv rau unc uns s32760 tshawb xyuas bolts yog li 10% sib dua thaum piv rau Qib 316 Stainless hlau. Lub stud tw s32760 pom cov kev ua tau zoo ntawm cryogenic kub kev teeb tsa ib yam nkaus. Qhov twg txhais tau hais tias ASTM A1082 unsom s i32760 muaj cov ntsiab lus sub-xoom ductility cov khoom qis rau ib qho kub ntawm rho 50¡Ãc.

Piv rau cov roj uas tsis muaj roj, cov kav hlau ob lav tau lav tau ntau dua rau kev pitting thiab kev ntxhov siab corrosion tawg. Lub caij no, peb ASTM A 789 \ / A 790 kav dej thiab cov raj muaj nyob rau ntau qhov sib txawv, gaugeses raws li cov neeg siv khoom lag luam.
Duplex stainless hlau muaj kev sib txuas ntawm ob ntu, ferrite thiab austenite hauv kwv yees sib npaug. Qhov no tso cai rau lawv kom tau txais txiaj ntsig los ntawm qhov zoo ntawm ob qho tib si ntawm cov hlau ua kom muaj zog, txhim kho werretability thiab kev tiv thaiv ntau dua rau ntau hom corrosion.
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.

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.

Lub tswv yim ntawm lub hnub qub steplex Qhov no yog feem ntau vim yog nce qib hauv statalmaking tshwj xeeb nrog kev hwm los tswj cov ntsiab lus nitrogen.

Super Duplex Zerless Hlau Zeron 100 pab ntxhua khaub ncaws, uas yog alloy steel tsom rau kev siv nyob rau hauv hostile cua tshuab. Super Duplex Zeron 100 xauv cov tshuab ntxhua khaub ncaws muaj cov cwj pwm hauv hiav txwv dej thiab ib yam nkaus hauv cov yeeb nkab ua haujlwm ua haujlwm.

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.

Lub 2205 duplex cov yeeb nkab tsim tsim raws li Astm A790 cov lus qhia tshwj xeeb tuaj yeem tsim los ntawm kev tsim kho lossis ib qho kev siv vuam.

Qhov zoo dua ntawm cov qauv dual

Duplex Stainless hlau Stainless hlau ua ke ua ke ntawm Austenitic thiab Ferritentic tsev neeg los muab cov txiaj ntsig tsawg dua - feem ntau ntawm tus nqi qis dua lwm cov hlau alloys.

Vim yog cov ntaub ntawv sib xyaw, lub zog thiab cov xeb tsis kam, cov flanges no tau siv nyob rau ntau yam kev siv.

Lub Austenitic-Ferritic tshuaj lom neeg cov khoom siv tau tshwm sim hauv cov khoom siv tshuab uas muaj peev xwm tiv nrog cov kev ntxhov siab ntawm kev siv hluav taws xob siab yuav ua rau cov tshuab tsis ua haujlwm. Qhov 2205 stainless hlau yeeb nkab steel yog dav siv hauv cov khoom siv tshuaj lom neeg, roj thiab roj ua kom huv, cov pa hluav taws xob ib puag ncig zoo li lub intergranular, corrasure, thiab pitting.

ASTM A790 und s31803 cov raj xaub s31803 tuaj yeem txias-dov-dov-dov-dov-colled muab rau lawv txhim kho cov khoom siv thiab kev ua tau zoo hauv cov tshuab sib txawv.

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.

Lub 2205 gasket yog hu ua lub duplex stainless hlau gaset vim nws muaj kev sib xyaw ua ke thiab tuaj yeem ua rau hauv freedeners vim nws cov siab corrosion. Nws tau muaj ntau dua corrosion tsis kam tshaj 316 stainless hlau thiab kuj tseem tiv taus kev ntxhov siab thiab chloride tawg. 2205 tau txiav txim siab ua tau zoo vim nws tsuas yog 5% npib tsib xee thiab yog tsis tshua kim dua hastelloy c276 fasteners.

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.

Duplex 2205 Stainless Hlau Round tuav (ASTM A276 \ / ANTM A479) ua rau pom kub ua kom zoo li 300,000. SS Qws tuaj yeem yooj yim welded los ntawm cov txheej txheem txheem feem ntau, tsuas yog yuav tsum tau ua yog siv cov tub lim hlau. Vim nws lub zog siab, lub tshuab luam ntawv yog tsawg.

Txawm hais tias thaum 2205 duplex stainless tubing cov khoom tau raug kub siab rau lub sijhawm kawg 5205 seamless raj yog raug rau embrittlement.

Super Duplex Stainless rau E.g. Alloy Uns S32750, muaj kev sib xyaw micreentructure ntawm ob qho tib si Austenite raws li ferrite nyob rau hauv ib tug sib npaug lossis 50 \ / 50 piv.

2205 stainless hlau ntawv muaj cov tensile muaj kev ntxhov siab thiab tsis muaj zog ntawm kev nthuav dav thiab tuaj yeem siv rau hauv cov khoom thauj, tsheb thauj khoom thiab nkoj raws li ntawv.

Feem ntau, chav hlau yas los ua cov hloov pauv rau qhov khoom siv zoo sib xws tab sis tsis tshua kim nyob hauv kev sib xyaw.

2507 Duplex yog cov tiv thaiv zoo ntawm cov tshuaj corrosion los ntawm cov organic acids xws li formic thiab acetic acid.

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.

2507 muaj qhov ntau dua chromium thiab molybdenum cov ntsiab lus uas muab cov super dupposion tsis kam dua li lwm cov qauv cov qauv duplex.

Txawm hais tias nws yog ib qho tseem ceeb kom nco ntsoov tias pitting corrosion tuaj yeem muaj kev txhawj xeeb hauv cov tshuaj chloride thaum oxidizing xov xwm tam sim no. Nyob rau hauv cov mob no, lub passive (tiv thaiv) txheej ntawm lub duplex 2205 cov khoom siv tuaj yeem cuam tshuam hauv pittingcompized yuav tshwm sim.

Duplex 2205 stainless hlau (Ferritic thiab Austenitic thiab Austenitic) tau siv dav hauv cov ntawv thov corrosion tsis kam thiab lub zog.

Seamless kav tseem ua tau cov khoom lag luam zoo li lub zog siab thiab tiv taus rau corrosion los ntawm cov organic acids. Tsis tas li, cov kav dej no tuaj yeem tiv taus cov inorganic acids thiab chloride ib puag ncig.

S32750 S32760 SUPLLEX Stuple Stainless Hlau Pipes Nrog Cov Pitting Zoo Tshaj

Muab nyob rau hauv anealed mob, nws muaj cov txiaj ntsig ib lub zog ntawm 80ksi (550MPA), uas yog siab dua li cov qib qis dua thiab cov qib qis dua.

Unr unic untl-theem steel puag ncig kev tiv thaiv kab mob chloside kev tawg, muaj zog tiv taus cov dej tawg lossis cov ntsev kom nruj.
