Incoloy 925 Stainless Hlau Flange muab kev tsis kam loj rau kev ntxhov siab corrosion tawg
SAE 304 stainless hlau yog qhov feem ntau steel hlau. Cov hlau muaj ob txoj kev chromium (nruab nrab ntawm 18% thiab 20%) thiab thib pua (nruab nrab ntawm 8%) [1] cov hlau uas yog cov qauv hlau tseem ceeb. Nws yog ib tus neeg siv tshuaj hlau tsis huv. Nws tsis tshua muaj hluav taws xob thiab cuam tshuam cov khoom siv hluav taws xob ntau dua li cov hlau. Nws sib nqus, tab sis tsis sib nqus dua li hlau. Nws muaj ntau dua corrosion tsis kam ntau dua li cov hlau tsis tu ncua thiab siv dav siv vim yog qhov yooj yim nyob rau hauv ntau yam duab. [1]
Cov txheej txheem teeb tsa rau 304 stainless hlau yog flange kuj yooj yim. Firstly, cov yeeb nkab kawg yog npaj los ntawm ntxuav nws thiab ua kom muaj tseeb tias 1.4301 flange yog pub dawb los ntawm kev puas tsuaj thiab khib nyiab. Tom ntej no, FM400 Flange yog muab tso rau ntawm cov yeeb nkab thiab ua kom raws li cov dej ntws nrawm lossis roj. Thaum kawg, cov bolts nruj rau cov chaw tsim khoom tshwj xeeb kom ntseeg tau tias muaj kev nyab xeeb txuas, kev saib xyuas kom tsis txhob saib xyuas cov bolts vim qhov no tuaj yeem ua rau puas tsuaj rau cov flange lossis yeeb nkab.
Featuring 347 stainless hlau rau kev ua tau zoo corrosion corrosion corrosion corrosionance, qhov no tau pom zoo wolding caj dab flange tuaj yeem txuas nrog weld ntawm lub caj dab. Welded thaj chaw tuaj yeem raug tshuaj xyuas yooj yim los ntawm radiography. Matched yeeb nkab thiab Flange Bore txo cov cua hlob thiab kev yaig hauv raj dej. Flange yog zoo heev rau siv nyob rau hauv koj daim ntawv thov tseem ceeb thiab yog qhov zoo rau siv nrog huab cua, dej, roj, nkev, thiab chav dej.
