Duplex stainless hlau s31083 s32205 flanges nrog pitting zoo thiab crevice corrosion tsis kam

Cov khoom siv S32205 DuPlex Asme asme sa182 pob tw Weld Flanges yog tsim nyog rau dej hiav txwv thiab cov khoom siv hluav taws xob tuaj yeem tiv thaiv kom sov txog 600,000Ãf, thaum tseem muaj cov yam ntxwv zoo.

Lub Austenitic feem ntawm Alloy yog vim li cas A182 Super Duplex Flanges tiv thaiv pitting, thiab corrosion. Feem ntau cov organic cov organic xws li acetic thiab formic acids ua rau muaj kev sib cav hauv ntau cov hlau alloys. Molybdenum, uas muaj lub siab chromium cov ntsiab lus, ua rau UN32750 pob tw Weld Flanges tiv taus corrosion nyob rau ib puag ncig muaj cov acids no.

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.

Super DupleX khawm Weld Flange rau cov ntawv thov uas xav tau lub zog zoo thiab corrosion tsis kam. Nws muaj cov tshuaj tiv thaiv corrosion zoo heev vim yog cov tshuaj lom neeg sib npaug. Ib qho ntxiv, nws ua tau zoo nyob rau hauv ib puag ncig muaj xws li chlorides, cov quav, sulfides, nitric acid, phosphoric acid, thiab lwm yam.

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.

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.

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.

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. Peb lub duplex 220. qhov chaw weld flanges yog cov kev xaiv siab heev, ua tau zoo nyob rau hauv feem ntau corrosive ib puag ncig, thiab muaj weldability ntau.

Taub qab weld flanges yog flanges tsim los txuas rau cov tshuab luam ntawv los ntawm taub qab vuam. Muaj ntau ntau yam tshwj xeeb ntawm flange. Taub qab Weld Flanges yog kim vim tias lawv cov neeg ua haujlwm ntev dua thiab cov neeg ua haujlwm siab rau kev sib chwv nrog cov ntawv thov kev ntxhov siab siab. Caj dab lossis hub hloov kev ntxhov siab rau cov yeeb nkab.

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.

Cov flanges no tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov. Daim ntawv thov kev lag luam ntawm Duplex flanges yog; Lawv siv rau hauv cov chaw tsim hluav taws kub roj, cov pa roj av, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv cua sov, thiab cov khoom siv ntub dej. Duplex steel flanges muaj nyob rau hauv ntau yam tsim muaj xws li lub tes tsho, pob tw wandd, dig muag, ncej puab pob qij txha thiab (ceg ob tog weld.

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.

Siv cov hlua S31803 DupleX steel yeeb nkab flanges ua kom muaj kev ua tau zoo, siab dua lub neej kev ua haujlwm. Vim tias dual xwm ntawm Austenitic thiab Ferritic Micrtructures tam sim no nyob rau hauv vaj huam sib luag, cov theem kub thiab ob sab flange cov khoom siv ntawm ob qho tib si steels.
