Cov ntawv thov ntawm Astm B424 uns n08825 Incoloy 825 Phaj
1. Kev Lag Luam Kev Lag Luam
Reactors, tso tsheb hlau luam, kev sib pauv cua sov, cov twj tso cua tshuab.
2. Roj thiab roj
- Qaub roj thiab roj av (H₂S / CO₂ ib puag ncig): siv rau cov cuab yeej downhole, li qub, pipelines.
- Offshore Platform: System Tsum Dej Hiav Txwv (xws li twj tam sim no, khoom muag Desalination)
3. Kev tiv thaiv kev nyab xeeb thiab kev tiv thaiv ib puag ncig
Flue Gas Desulfurization (FGD) SYSTEM: FLUE, Scrubber Cheebtsam, tiv taus cov tub rog uas muaj cov roj ntub thiab corrosion ntub dej.
4. Marine Engineering
- Evaporators, rajpelines, Kuj rau chloride ion corrosion thiab kev sib kis roj ntsha.
- Nkoj Chaw: Tus kiv cua Ncej, Twj Tso Kua Dej, Haum rau kev tshuaj tsuag ntsev
5. Daim ntawv thov kub siab
Kev kho cua sov kom sov rauve:ASTM B424 UNRICS N08825 PHAJresistant rau cov high kub oxidation (txog li 550 degree), siv rau cua sov rollers thiab combustion Chamber Liners.
6. Pulp thiab daim ntawv lag luam
Cov khoom siv tshuaj ua kom dawb thiab zom: tiv thaiv kev corrosion los ntawm cov tshuaj ntsuab corrosive xws li chlorides thiab chlorine dioxide.
Vim li cas thiaj xaiv ASTM B424 UN tsis N08825 PHAJ?
Corrosion Kuj
- Acidic ib puag ncig: resistant rau sulfuric acid (siab tsawg dua los yog sib npaug rau 70%), phosphoric acid, acetic acid, acetic acid thiab cov acids acids.
- Alkaline ib puag ncig: resistant rau caustic alkali (xws li naoh) corrosion.
- Chlorine-muaj ib puag ncig: tiv taus pitting thiab kev nyuaj siab corrosion tawg (SCC) tshwm sim los ntawm dej hiav txwv, noj tshuaj chloride.
- Resistant rau hydrogen sulfide (h₂s) corrosion (hauv cov acidic ib puag ncig cov roj thiab roj ntau lawm (muaj h₂s / CO₂)
Siab Zog
- Chav chav kub tensile lub zog ntau dua los yog sib npaug rau 586 MPa, tawm kom muaj zog dua los yog sib npaug rau 241 MPA. Ductility zoo (elongation ntau dua los yog sib npaug rau 30%), zam brittle bracture.
