Feem ntau cov khoom siv stainless hlau yog cov khoom siv flange tseem ceeb, nws yog qhov chaw txhawj xeeb tshaj plaws yog qhov teeb meem zoo. Qhov no kuj yog lub ntsiab lus tseem ceeb tshaj plaws nyob rau hauv qhov zoo ntawm stainless hlau flange manufacturers. Yog li yuav ua li cas ntxuav cov stains seem ntawm lub flange kom raug thiab sai sai?

Feem ntau siv flange yog 304 stainless hlau. Flanges ua los ntawm cov khoom siv no yuav raug corroded ntawm 20 ℃ thiab 10% nitric acid ntawm tus nqi tsawg dua 0.1 hli hauv ib xyoos; Nyob rau hauv 10% boiling acetic acid, tus nqi corrosion yog tsawg dua 0.1 hli ib xyoo; Corrosion tus nqi tsawg dua 0.1 hli hauv ib xyoos hauv 50% citric acid; 20% ntawm cov poov tshuaj hydroxide yog corroded ntawm tus nqi tsawg tshaj li 0.1 hli ib xyoo. Ntawm 60 ℃, tus nqi corrosion ntawm 80% phosphoric acid tseem tsawg dua 0.1 hli ib xyoo. Tab sis ntawm 50 ℃, tus nqi corrosion ntawm 2% sulfuric acid yog 0.016 hli ib xyoo. Yog li ntawd, stainless hlau raj lined los ntawm txias dov stainless hlau sawb welded nrog stainless hlau welded yeeb nkab fittings thiab Yixing stainless hlau flange yuav siv tau los thauj tsis muaj zog acid los yog qaug zog alkaline tshuaj kua. Stainless hlau flanges feem ntau yog ua nyob rau hauv lub tshav pob ntawm cov plua plav, uas yuav tas li ntog ntawm cov khoom siv. Cov no tuaj yeem raug tshem tawm nrog dej lossis alkaline daws. Tab sis rau qhov adhesion ntawm av yuav tsum tau siv cov dej siab los yog chav dej los ntxuav. Tom qab ntawd muaj qhov teeb meem ntawm cov hlau ntab hmoov los yog hlau embedded. Ntawm txhua qhov chaw, cov hlau dawb yuav xeb thiab corrode stainless hlau flanges. Yog li nws yuav tsum tau muab tshem tawm. Float hmoov feem ntau yuav raug tshem tawm nrog rau cov hmoov av. Muaj zog adhesion thiab yuav tsum tau kho nrog embedded hlau.

Cov saum toj no yog txoj kev ntxuav ntawm cov seem seem ntawm cov hlau stainless flange, stainless hlau tsis yooj yim, tab sis kuj yuav tsum tau ntxuav kom zoo thiab tswj xyuas.
