UNS C44300 Admiralty Brass Tube yog dab tsi?
UNS C44300yog tin -cov kabmobAdmiralty Brass: 70.0-73.0% tooj liab, zinc balance, nrog0.9-1.2% yog 'thiab txhob txwm ua0.02-0.06% arsenicntxiv. Tin lifts tsis kam mus rau kev xeb dav dav, thaum arsenic inhibits dezincification - kev xaiv poob ntawm zinc uas ua rau lub neej luv hauv cov dej txhoj puab heev. Cov hmoov txhuas, hlau thiab tag nrho cov impurities raug kaw kom nruj ASTM B111 txwv.
Lub alloy yog tsim raws liseamless txias-kob raj, ib txwm nyob rau hauv qhov mob annealed kom nws tuaj yeem dov, U- khoov thiab nthuav mus rau hauv cov ntawv raj yam tsis muaj tawg.
Annealed C44300 raj yog teev tshwj xeeb rausteam deg condensers, roj coolers, feedwater heaters thiab txheej txheem exchangerskhiav ntawm dej tshiab, chav dej condensate los yog dej me me brackish. Thermal conductivity zaum ze110 W/m·K- kwv yees li ob npaug ntawm tooj liab-nickel - uas ua kom sov- hloov nto compact.
Sustained siab - dej hiav txwv ceev tsis yog nws lub luag haujlwm ib txwm muaj; qhov twg cov tshuaj chloride siab, cov khoom tshwj xeeb feem ntau txav mus rau tooj liab- qib nickel.
UNS C70600 Copper -Nickel Tube yog dab tsi?
UNS C70600, feem ntau sau ua Cu-Ni 90/10, yog tooj liab-nickel alloy nrog9.0-11.0% npib tsib xee, 1.0-1.8% yog ', mus txog 1.0% manganese thiab88.6% tooj liab yam tsawg kawg nkaus. Qhov sib ntxiv ntawm cov hlau tsis yog qhov xwm txheej - nws yog qhov ua rau cov hlau tsis muaj zog rau kev yaig -corrosion hauv qab dej hiav txwv ntws.
Hauv kev pab cuam lub alloy tsim ib tug nyias, adherent oxide zaj duab xis uas hloov sai sai tom qab kev puas tsuaj, uas yog vim li cas nws outperforms tooj dag nyob rau hauv chloride - nplua nuj dej txias.
C70600 raj yog tus qauv xaiv rauseawater-cooled condensers, desalination nroj tsuag, shipboard txias tshuab thiab offshore exchangers, thiab tolerates flow velocities ntawm roughly2.5–3.5 m/sthaum hlau cov ntsiab lus thiab exchanger tsim tso cai. Thermal conductivity qis dua, nyob ib ncig ntawm45 W/m·K, yog li ntau qhov chaw saum npoo yog xav tau rau tib lub luag haujlwm.
Ob leegC44300 thiab C70600kuj tseem siv ua ke hauv cov khoom sib xyaw: Admiralty Brass ntawm qis -chloride sab, tooj liab-nickel qhov twg dej hiav txwv hla.
C44300 vs C70600 - Yuav Ua Li Cas Xaiv
Qhov kev txiav txim siab feem ntau tig rau ntawm qhov nruab nrab cua txias thiab qhov xav tau cua sov- hloov chaw, tsis nyob ntawm tus nqi ib leeg.
