Xaiv txoj cai Stainless hlau rau kev ua tshuaj

Hauv kev lag luam tshuaj lom neeg, kev xaiv cov khoom siv ntau tshaj qhov kev ua tau zoo - nws yog qhov teeb meem ntawm kev nyab xeeb, kav ntev, thiab kev siv nyiaj. Cov cuab yeej siv hauv qhov haujlwm no yuav tsum tiv tausCov tshuaj aggressive, kub siab, siab siab, thiabcorrosive ib puag ncignyob rau txhua hnub. Qhov no yog qhov twgstainless hlauua pov thawj tias yog qhov kev xaiv tshwj xeeb.

Tab sis tsis yog tag nrho cov hlau stainless yog tsim sib npaug. Xaiv cov qib zoo yog qhov tseem ceeb rau kev ua tiav lub neej ua haujlwm ntev, zam cov khoom siv tsis ua haujlwm, thiab ua kom muaj kev ua haujlwm zoo. Hauv tsab xov xwm no, peb tshawb nrhiav cov ntsiab lus tseem ceeb rau kev xaiv stainless hlau hauv kev ua tshuaj lom neeg, cov qib feem ntau, thiab lawv cov txiaj ntsig tshwj xeeb. coj los rau kojsasaalloy, koj tus khub ntseeg siab hauv cov ntaub ntawv stainless hlau rau kev lag luam zoo.

Vim li cas Stainless Hlau yog qhov tseem ceeb hauv kev ua tshuaj

Stainless hlau muaj ib tug tshwj xeeb sib tov ntawmcorrosion kuj, lub zog, kub tsis kam, thiab huv. Nws cov chromium-nplua nuj muaj pes tsawg leeg tsim ib tug passive oxide txheej uas tiv thaiv nto los ntawm tshuaj tua kab mob - txawm nyob rau hauv lub xub ntiag ntawm muaj zog acids, alkalis, thiab cov kuab tshuaj.

Cov txiaj ntsig tseem ceeb rau thaj chaw tshuaj lom neeg muaj xws li:

• Zoo heev tiv taus pitting thiab crevice corrosion

• Muaj zog mechanical zog ntawm qhov kub thiab txias

• Yooj yim ntawm fabrication thiab vuam

• Tsawg txij nkawm thiab kev pab lub neej ntev

• Compatibility nrog tu cev thiab huv-hauv-chaw (CIP) systems

At sasaalloy, peb muab tshuaj-qib stainless hlau cov khoom uas ua tau raws li cov qauv thoob ntiaj teb thiab cov neeg siv khoom tshwj xeeb.

Yam yuav tsum tau xav txog thaum xaiv Stainless hlau

Thaum xaiv stainless hlau rau kev siv tshuaj, engineers yuav tsum soj ntsuam:

• Tshuaj muaj pes tsawg leeg ntawm cov txheej txheem media

• Concentration, kub, thiab siab

• Hom corrosion (xws li, dav dav, pitting, kev nyuaj siab tawg)

• Vuam thiab fabrication xav tau

• Kev tswj hwm thiab tu cev ua raws cai

• Nqi thiab muaj

Kev tsis sib haum xeeb ntawm ib puag ncig thiab cov khoom siv tuaj yeem ua rauua tsis tiav ntxov, raug nqi kaw, thiab tej zaum yuav muaj kev phom sij.

Common Stainless Hlau Qib rau Tshuaj Ua Haujlwm

1. 304 Stainless hlau

• Kev sib xyaw18% chromium, 8% npib tsib xee

• Qhov zoo: Zoo corrosion kuj, yig

• Kev txwv: Tsis zoo rau qhov chaw uas muaj chloride nplua nuj

• Daim ntawv thov: Cia tank, kav dej, kev txhawb nqa

304 yog dav siv rau cov khoom siv tshuaj lom neeg, tshwj xeeb tshaj yog nyob qhov twgme ntsis acidslos yog tsis muaj chloride ib puag ncig muaj.

2. 316 / 316L Stainless hlau

• Kev sib xyaw16% chromium, 10% nickel, 2% molybdenum

• Qhov zoo: Txhim khu kev tiv thaiv rau chlorides thiab acidic ib puag ncig

• Daim ntawv thov: Reactors, kub exchangers, evaporators, li qub

316l uaqis carbon cov ntsiab lus, ua kom zoo rauwelded kev sivqhov twg corrosion ntawm cov pob qij txha tuaj yeem ua rau muaj kev pheej hmoo.

3. 317L Stainless hlau

• Kev sib xyaw: Siab molybdenum tshaj 316L

• Qhov zoo: Txhim khu kev tiv thaiv rauchloride pitting thiab crevice corrosion

• Daim ntawv thov: Pulp thiab ntawv bleaching, tshuaj reactors, scrubbers

Thaum 316L ntog luv nyob rau hauv ib puag ncig corrosive heev, 317L muaj kev lag luam nce qib hauv kev tiv thaiv.

4. 904L Stainless hlau

• Kev sib xyaw: High nickel thiab molybdenum cov ntsiab lus

• Qhov zoo: Zoo heev hauvmuaj zog acid ib puag ncigsuav nrog sulfuric, phosphoric, thiab acetic acids

• Daim ntawv thov: Kub exchangers, pickling khoom, acid ntau lawm

904L tiv thaiv ob qho tib si txo thiab oxidizing cov neeg ua haujlwm thiab tshwj xeeb tshaj yog tiv thaivaggressive mediantawm qhov kub thiab txias.

5. Duplex Stainless Steels (piv txwv li, 2205, 2507)
