1. Kev lag luam roj thiab roj (Primary Application Field)
Qhov no yog qhov loj tshaj plaws thiab tseem ceeb tshaj plaws hauv daim ntawv thov rau Incoloy 925, vim nws muaj peev xwm tiv taus cov kev mob hnyav ntawm cov dej ntws, nruab nrab, thiab qis qis:
Upstream Exploration thiab Production:
Downhole Cheebtsam: Tubing hangers, valve trim, sucker rods, twj tso kua mis shafts, thiab tiav cov cuab yeej. Cov khoom no raug rau cov kua dej corrosive uas muaj H₂S, CO₂, chloride ions, thiab xuab zeb yaig, qhov twg Incoloy 925 outperforms standard stainless hlau.
Cov khoom siv hauv lub taub hau: Christmas ntoo Cheebtsam, choke li qub, thiab cov khoom sib txuas, uas yuav tsum tau muaj zog thiab corrosion kuj los tswj kev sib khi ruaj khov nyob rau hauv siab thiab kub (HPHT).
Kev thauj mus los hauv nruab nrab thiab cia:
Pipeline pigging cov cuab yeej, ntws tswj li qub, thiab cov khoom ntim cia hauv lub cev tuav cov roj qaub, roj av, thiab cov dej tsim tawm.
Downstream Refining thiab Petrochemicals:
Thaum tshav kub kub exchanger raj, reactor internals, thiab catalyst txhawb daim phiaj nyob rau hauv units ua acidic hydrocarbons los yog corrosive txheej txheem ntws.
2. Aerospace thiab Aviation Industry
Incoloy 925 yog siv rau nruab nrab - qhov kub thiab txias cov khoom siv uas xav tau qhov sib npaug ntawm lub zog thiab kev tiv thaiv corrosion:
Aircraft cav accessories, xws li roj system li qub, hydraulic system Cheebtsam, thiab tsaws iav bushings. Nws cov nag lossis daus- muaj peev xwm hardening tso cai rau nws khaws lub zog ntawm qhov kub txog li 540℃(1000℃F), thaum nws tiv thaiv corrosion tiv thaiv cov dav hlau cov pa paug thiab huab cua raug.
Aerospace fasteners thiab structural brackets rau aircraft raug rau marine los yog industrial atmospheric ib puag ncig.
3. Kev lag luam tshuaj thiab kws tshuaj
Lub alloy tsis kam mus rau ntau yam ntawm cov tshuaj corrosive ua rau nws haum rau:
Cov cuab yeej siv tshuaj: Cov khoom sib tov sib xyaw, cov agitator blades, valve stems, thiab tshav kub exchanger tubes tuav cov kua qaub (xws li sulfuric acid, phosphoric acid nyob rau hauv dilute mus rau nruab nrab concentrations), alkalis, thiab ntsev tov. Nws muaj txiaj ntsig tshwj xeeb hauv kev txo cov cheeb tsam uas cov hlau tsis muaj steel yuav raug kev txom nyem los ntawm kev xeb tsis sib xws.
Pharmaceutical manufacturing: Reactors, filtration systems, thiab hloov twj tso kua mis rau kev tsim tshuaj, qhov uas siab purity thiab corrosion kuj tseem ceeb heev los tiv thaiv cov khoom sib kis.
4. Marine thiab Offshore Engineering Kev Lag Luam
Nyob rau hauv marine ib puag ncig nrog cov tshuaj chloride siab, Incoloy 925 resists pitting thiab crevice corrosion zoo dua 316 stainless hlau, ua rau nws zoo tagnrho rau:
Offshore platform Cheebtsam: Riser clamps, seawater intake screens, thiab subsea hardware.
Marine propulsion systems: Shafts, propeller shafts, thiab seawater cooling system Cheebtsam rau nkoj thiab submarines.
Desalination nroj tsuag: Membrane txhawb thav ntawv, twj impellers, thiab siab hlab ntsha tuav dej ntsev thiab brine.
5. Kev lag luam tsim hluav taws xob
Rau cov pa thiab txuas txuas ntxiv fais fab nroj tsuag ua haujlwm hauv corrosive tej yam kev mob:
Fossil roj fais fab nroj tsuag: Tshauv tuav cov khoom siv, flue gas desulfurization (FGD) cov khoom siv, thiab cov raj condenser hauv cov chaw ntug dej hiav txwv uas cov dej txias muaj cov tshuaj chloride siab.
Geothermal fais fab nroj tsuag: Wellhead Cheebtsam thiab tshav kub exchangers raug corrosive geothermal kua nrog siab chloride thiab sulfide cov ntsiab lus.
6. Kev lag luam mining thiab Mineral processing
Incoloy 925 yog ua haujlwm nyob rau hauv cov khoom siv ua aggressive ores thiab slurries:
Twj shafts, impellers, thiab valve trim rau cov ntxhia ua cov nroj tsuag tuav cov kua qaub slurries (xws li, tooj liab, zinc, thiab nickel leaching circuits).
Laum rods thiab downhole cov cuab yeej rau mining ua hauj lwm nyob rau hauv saline los yog acidic av puag ncig.
