UNS C44300 Admiralty Brass Tube PDF
ASTM B111 C44300 tooj liab tubing yog dab tsi?
Admiralty Brass (C44300) thiab Copper-Nickel alloys (feem ntau 90/10 Cu-Ni lossis 70/30 Cu-Ni) yog ob qho tib si siv hauv marine thiab industrial heat exchange and piping systems, tab sis lawv yog cov tsev neeg sib txawv alloy thiab muaj qhov sib txawv corrosion kuj profiles. C44300 yog ib qho dezincification{10}} tiv taus tooj dag, thaum Cu-Ni alloys yog ib zaug- cov kev daws teeb meem uas tau txais txiaj ntsig zoo dua rau corrosion thiab biofouling kuj.

Kev soj ntsuam ntxaws ntxaws
Corrosion Resistance nyob rau hauv Seawater:
C44300 ua tau zoo nyob rau hauv cov xwm txheej tshwj xeeb: nws cov arsenic ntxiv ua rau nws muaj zog heev rau dezincification, hom tsis ua haujlwm rau cov tooj dag nyob rau hauv tsis tu ncua lossis qeeb - txav dej. Txawm li cas los xij, nws tseem muaj kev cuam tshuam rau ammonia nres (kev ntxhov siab corrosion cracking) thiab tsuas muaj kev ua haujlwm tsis zoo rau siab - dej hiav txwv ceev.
Cu-Ni (C70600) muaj dav -spectrum, superior corrosion kuj nyob rau hauv seawater. Nws cov ntsiab lus npib tsib xee thiab hlau txhawb kev tsim kom nruj, ua raws, thiab tiv thaiv oxide zaj duab xis uas tiv thaiv ntau yam kev tawm tsam, suav nrog:
Erosion-corrosion nyob rau hauv high flow velocities.
Kev nyuaj siab corrosion cracking.
Marine biofouling (cov ntsiab lus nickel yog ntuj biocide).
Thermal thiab Mechanical Performance:
Thaum tshav kub kub hloov: C44300 muaj ze li ob npaug ntawm cov thermal conductivity ntawm 90/10 Cu-Ni. Qhov no ua rau nws muaj peev xwm thermally npaum li cas hauv txoj kev xav, tab sis tsuas yog tias cov hlab ntsha tseem huv. Cu-Ni's fouling resistance feem ntau ua rau kev ua haujlwm ntev dua -.
Lub zog thiab Erosion Resistance: Cu-Ni alloys muaj zog dua thiab tiv taus kev yaig los ntawm cov xuab zeb, silt, thiab siab - dej nrawm. Qhov no tso cai rau cov phab ntsa nyias nyias thiab cov qauv tsim siab dua.
Kev siv ib puag ncig:
Xaiv Admiralty Brass (C44300) thaum: Daim ntawv thov feem ntau yog cov khoom siv hluav taws xob sib hloov lossis cov condensers siv cov dej txias uas yog cov tshiab, brackish, los yog cov dej hiav txwv huv si nrog kev tswj ceev ceev. Nws yog tus nqi -kev daws teeb meem zoo qhov twg dezincification yog qhov kev txhawj xeeb tseem ceeb thiab cov dej tsis muaj zog heev.
Xaiv tooj liab -Nickel (C70600) thaum: Cov kev pabcuam suav nrog tag nrho - dej hiav txwv muaj zog, tshwj xeeb tshaj yog nrog cov nqi ntws siab, cov xuab zeb / cov hmoov av, lossis muaj peev xwm biofouling siab. Nws yog tus qauv rau cov kav dej hiav txwv, kev siv ntug dej hiav txwv, nkoj hull sheathing, thiab condensers nyob rau hauv hnyav marine ib puag ncig qhov kev ntseeg siab thiab lub neej ntev yog qhov tseem ceeb.
Qhov kev xaiv tsis tshua muaj qhov "zoo dua," tab sis qhov twg yog qhov tsim nyog dua rau cov dej chemistry, dej ntws, thiab tag nrho cov nqi ntawm cov tswv cuab. Admiralty Brass yog ib qho tshwj xeeb, tus nqi - kev daws teeb meem zoo rau kev tswj dej. Copper-Nickel yog tus hwm zoo, muaj ntau yam khoom siv engineering rau kev thov, tag nrho - dej hiav txwv kev pab cuam qhov twg ntev - lub sij hawm kev ntseeg siab tshaj tus nqi pib. Rau cov mob hnyav tshaj plaws (piv txwv li, cov xuab zeb siab), 70/30 Copper -Nickel (C71500) yuav yog qhov kev xaiv muaj zog dua li 90/10.
