Basic Introduction
Duplex stainless hlau valve npas yog tsim los ntawm austenitic -ferritic duplex stainless hlau (xws li 2205, 2507, thiab lwm yam), combining zoo heev corrosion kuj ntawm austenitic stainless hlau nrog lub siab zog yam ntxwv ntawm ferritic stainless hlau. Nyob rau hauv ib puag ncig chloride, nws tsis kam mus rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion cracking (SCC) yog ho superior rau zoo tib yam austenitic stainless hlau (xws li 304, 316). Nyob rau tib lub sijhawm, txhua yam muaj zog (yield zog txog ob zaug ntawm 316L) thiab qaug zog tiv thaiv tau zoo heev. Nws cov qauv duplex endows cov khoom nrog zoo heev yaig thiab hnav tsis kam. Ua ke nrog siab -precision spherical ua, nws tuaj yeem ua haujlwm ntev - lub sijhawm ua haujlwm ruaj khov nyob rau hauv kev sib xyaw ua ke ntawm nruab nrab corrosion thiab siab alternating siab loads. Cov khoom yog tshwj xeeb tshaj yog haum rau cov dej tswj scenarios uas yuav tsum tau muaj corrosion kuj thiab cov yam ntxwv lub zog, xws li seawater kho, roj thiab roj tsheb thauj mus los, tshuaj desulfurization, thiab ntug hiav txwv dej pipelines.

FAQ
Dab tsi yog qhov tseem ceeb ntawm duplex stainless hlau valve pob?
Lub ntsiab kom zoo dua ntawm duplex stainless hlau valve npas nyob rau hauv lub synergistic nyhuv ntawm "siab zog + siab corrosion kuj." Nws lub zog tawm los yog kwv yees li ob zaug ntawm 316L stainless hlau, tso cai rau nws tiv taus siab dua ntawm tib phab ntsa tuab; Tsis tas li ntawd, vim nws cov austenitic-ferrite biphase qauv tsis hnov tsw rau chloride ions, nws tsis kam mus rau pitting, crevice corrosion, thiab kev nyuaj siab corrosion tawg deb tshaj li cov pa austenitic stainless hlau, ua rau nws tshwj xeeb tshaj yog haum rau hloov cov khoom siv stainless hlau zoo tib yam hauv marine engineering thiab roj thiab roj tsheb thauj mus los scenarios, high salinity loads. nyob ua ke.
Dab tsi yog qhov txawv ntawm duplex stainless hlau valve npas thiab zoo tib yam austenitic stainless hlau valve pob (xws li 316L)?
316L muaj ib qho -theem austenitic qauv nrog txwv lub zog thiab tiv thaiv kev ntxhov siab corrosion, thiab ua rau muaj kev pheej hmoo ntawm pitting thiab kev ntxhov siab corrosion tawg hauv chloride ion ib puag ncig; Vim yog ob qho -theem qauv uas muaj qhov sib npaug sib npaug ntawm cov khoom siv austenitic thiab ferritic, lub zog tawm los yog kwv yees li ob npaug, qhov sib npaug pitting (PREN) tus nqi siab dua, thiab kev ntxhov siab corrosion kuj tseem txhim kho. Nyob rau hauv tib yam corrosive nruab nrab tej yam kev mob, duplex stainless hlau valve pob tuaj yeem ua haujlwm zoo nyob rau hauv siab dua chloride ion concentrations thiab kub ntau yam.
Yuav xaiv li cas ntawm 2205 thiab 2507 cov ntaub ntawv?
2205 yog ib qho kev lag luam duplex stainless hlau, haum rau nruab nrab chloride ion concentrations (xws li seawater txias thiab desalination pretreatment) thiab cov pa roj thiab roj; 2507 yog super duplex stainless hlau nrog ntau dua chromium, molybdenum, thiab nitrogen cov ntsiab lus, muaj zog tiv taus pitting thiab crevice corrosion, thiab siab dua pitting kub, haum rau hnyav corrosive ib puag ncig xws li kub, siab salinity, muaj zog acidic media, thiab tob - hiav txwv roj thiab roj extraction. Kev xaiv tus qauv yuav tsum raug soj ntsuam zoo raws li chloride ion concentration, kub, pH tus nqi, thiab qib siab ntawm qhov nruab nrab.
Dab tsi tshwj xeeb yuav tsum muaj rau vuam los yog ua duplex stainless hlau valve pob?
Thaum lub sij hawm forging thiab tom qab ua tiav, cov tshuaj kho qhov kub thiab txias ntawm duplex stainless hlau valve pob yuav tsum nruj me ntsis tswj kom muaj qhov sib npaug ntawm austenite thiab ferrite, tiv thaiv nag lossis daus ntawm cov hlau tsis zoo (xws li σ theem), yog li lav tiv thaiv corrosion thiab cov khoom siv kho tshuab. Peb lub tuam txhab muaj cov txheej txheem thermal ua kom paub tab thiab cov txheej txheem kev daws teeb meem los xyuas kom meej cov khoom microstructure uniformity thiab kev ua tau zoo sib xws, ua tau raws li qhov yuav tsum tau ua kom zoo rau siab - kawg valve.
