Cov qhab nia xaiv tau
- Rau qhov nruab nrab corrosive ib puag ncig-xws li cov uas muaj cov tshuaj chlorides tsawg lossis cov organic acids-S31803 / S32205 (2205 duplex stainless hlau) yog qhov kev xaiv tsim nyog. Tus nqi qis dua super duplex stainless hlau, nws yog dav siv nyob rau hauv tsis yog - cov txheej txheem tseem ceeb piping nyob rau hauv chemical processing nroj tsuag, thiab nyob rau hauv cov dej kho systems.
- Rau ib puag ncig corrosive heev -xws li cov uas muaj qhov kub thiab txias, muaj zog acids, los yog siab concentrations halides -Alloy 625 los yog Alloy C276 tej zaum yuav raug xaiv; Txawm li cas los xij, cov kev xaiv no tuaj ntawm tus nqi siab dua.
- Rau cov khoom siv tshuaj yeeb dej caw ua haujlwm ntawm qhov kub thiab txias, tsis muaj cov tshuaj chloride ions, thiab tsuas yog me ntsis corrosion, 304 lossis 316 stainless hlau yog qhov kev xaiv siv tau. Thaum muab tus nqi qis tshaj plaws, nws lub neej kev pab cuam tsawg dua ib -peb peb ntawm super duplex stainless hlau.
thaj chaw thov
ASTM A790 UNS S32750 / S32760 Super Duplex stainless hlau kav yog dav siv nyob rau hauv cov ntaub ntawv hauv qab no:

FAQ
Q: Dab tsi yog qhov kev ua haujlwm kub rau Super Duplex steel kav?
A: Ob leeg S32750 thiab S32760 yog tsim rau ntev - siv nyob rau hauv qhov kub ntawm -50℃rau +300℃. Txawm li cas los xij, lawv yuav tsum tsis txhob raug siv ntev ntawm qhov kub siab tshaj 300℃(570℃F), vim qhov no tuaj yeem yooj yim ua rau cov khoom embrittlement thiab degradation ntawm corrosion kuj.
Q: Koj puas muab kev kuaj thiab ntawv pov thawj dab tsi?
A: Peb muab 100% hydrostatic kuaj, eddy tam sim no kuaj (ET), ultrasonic kuaj (UT), thiab PMI spectroscopic tsom xam. Txhua batch ntawm cov khoom yog nrog los ntawm EN 10204 3.1 lossis 3.2 daim ntawv pov thawj khoom.
Q: Koj puas txhawb qhov kev hloov kho ntawm qhov tsis yog - qhov ntev thiab kev kho tshwj xeeb?
A: Peb muab kev kho kom haum rau txhua yam uas tsis yog -txoj kab uas hla sab nraud, phab ntsa tuab, thiab qhov ntev ruaj khov. Tsis tas li ntawd, peb muab ntau yam kev kho mob saum npoo av, suav nrog pickling thiab passivation, sab hauv thiab sab nrauv daim iav polishing, thiab ci annealing.
