Cov qhab nia xaiv tau
- Rau cov txheej txheem kev lag luam kub pauv kev ua haujlwm ntawm ambient kub thiab kub txog li 350℃-thiab thaum tsis muaj corrosive media heev-SA213 TP304 yuav raug xaiv los hloov; TP304 yog tus nqi ntau dua - siv tau, thaum nws cov khoom siv hluav taws xob thiab hluav taws xob hloov hluav taws xob ua tau raws li cov qauv xav tau.
- Rau siab dua -kub siv xws li boilers, superheaters, thiab petrochemical siab- kub exchangers, TP347/347H yog ib qho kev xaiv tsim nyog, muab superior siab - kub lub zog thiab tsis kam mus rau rhiab heev piv rau TP321.
- Yog tias cov cuab yeej muaj kev tsim qauv siab thiab siab -chloride media, nrog rau kev ua haujlwm kub tsis tshaj li ntawm 300 degree, duplex stainless hlau yuav raug suav hais tias yog lwm txoj hauv kev rau TP316L kom tso cai rau txo cov phab ntsa tuab thiab cov khoom siv qis dua.

FAQ
Q: Dab tsi yog qhov ntsuas kub siab tshaj plaws rau TP321 stainless hlau U- raj?
A: Hauv kev daws teeb meem -annealed xeev, TP321 U- cov hlab tuaj yeem tiv taus ntev - lub sijhawm ua haujlwm kub kub txog li 550℃thiab luv luv - lub sijhawm kub siab ntawm 600℃. Nyob rau hauv no ntau yam, lawv tuav ruaj khov mechanical thiab corrosion-cov khoom tiv taus thiab tiv taus deformation lossis tsis ua haujlwm.
Q: Vim li cas TP316L yog qhov tsim nyog rau cov khoom siv hluav taws xob ntau dua li tus qauv 316?
A: TP316L muaj cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.03%, uas yog qis dua li tus qauv 316. Qhov no tiv thaiv kev cuam tshuam ntawm intergranular corrosion los ntawm vuam los yog ntev - lub sij hawm kev pab cuam thiab tshem tawm qhov xav tau kev kho mob theem nrab. Nws yog qhov zoo- haum rau siab- zaus vuam sib dhos thiab txuas mus ntev- lub sijhawm ua haujlwm ntawm cov khoom siv hluav taws xob sib hloov, ua rau lub neej ua haujlwm ntev dua.
Q: Dab tsi tsis yog - kuaj kev puas tsuaj thiab kev ntsuas siab muaj nyob rau?
A: Peb muab 100% hydrostatic kuaj, pneumatic kuaj, eddy tam sim no kuaj, ultrasonic kuaj, kua penetrant kuaj, kuaj radiographic, thiab endoscopic soj ntsuam. Peb tuaj yeem muab cov txheej txheem kuaj raws li cov kev cai tshwj xeeb.
