Feem ntau stainless hlau cov khoom yog lub ntsiab flange khoom, nws yog qhov muaj kev txhawj xeeb tshaj plaws yog qhov zoo ntawm cov teeb meem. Qhov no kuj yog lub ntsiab lus tseem ceeb tshaj plaws hauv qhov zoo ntawm stainless hlau Flange Cov Chaw Tsim Tshuaj. Yog li yuav ua li cas ntxuav cov khoom seem ntawm cov flange kom raug thiab sai?

Qhov feem ntau siv flange yog 304 stainless hlau. Flanges ua los ntawm cov khoom no yuav corroded ntawm 20 ℃ thiab hauv 10% nitric acid ntawm tus nqi tsawg dua 0.1 hli ib xyoos; Nyob rau hauv 10% boiling acetic acid, tus corrosion tus nqi yog tsawg dua 0.1 hli ib xyoo; Corrosion tus nqi ntawm tsawg dua 0.1 hli ib xyoos hauv 50% citric acid; 20% ntawm cov poov tshuaj hydrocrod yog corroded ntawm tus nqi tsawg dua 0.1 mm ib xyoos. Thaum 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 xyoos. Yog li ntawd, lub stainless hlau raj kab los ntawm cov khaub noom txias stainless hlau welded cov yeeb nkab welded nrog stainless hlau flange tuaj yeem siv cov kua hluav taws xob tsis muaj zog lossis qaug zog alkaline. Stainless hlau flanges feem ntau yog ua rau hauv thaj teb ntawm plua plav, uas yuav poob rau saum npoo ntawm cov khoom siv. Cov no tuaj yeem raug tshem tawm nrog dej lossis alkaline daws teeb meem. Tab sis rau cov nplaum ntawm cov av yuav tsum tau siv cov dej siab los yog dej kom huv. Tom qab ntawd muaj qhov teeb meem ntawm cov hlau ntab hmoov lossis cov hlau kos duab. Ntawm txhua qhov chaw, hlau dawb yuav xeb thiab corrode stainless hlau flanges. Yog li nws yuav tsum tau huv. Float hmoov feem ntau yuav tau muab tshem tawm nrog rau hmoov av. Cov nplaum muaj zog thiab yuav tsum tau kho nrog cov hlau kos duab.

Qhov saum toj no yog txoj kev ntxuav cov txheej txheem ntawm cov stains stains ntawm lub stainless hlau flange, tab sis kuj yuav tsum tau huv thiab khaws cia.
