UNS C44300 Admiralty Brass Tube PDF
Thaum xaiv ntawm Admiralty Brass (C44300) thiab Naval Brass (C46400), engineers ntsib qhov kev txiav txim siab tseem ceeb uas txuas ntxiv tshaj qhov tsuas yog xaiv "marine- qib tooj dag." Cov alloys no sawv cev rau ob qho tib si engineering philosophies optimized rau txawv tsis ua hauj lwm hom thiab cov kev pab cuam. C44300 yog qhov tseem ceeb ntawm kev xeb- cov khoom tshwj xeeb, thaum C46400 yog cov khoom siv kho kom zoo- cov khoom siv tau zoo. Phau ntawv qhia no muab ib txoj hauv kev rau kev xaiv raws li cov kev xav tau ntawm daim ntawv thov, ib puag ncig yam, thiab qhov tseem ceeb ntawm kev ua haujlwm.
Kev xaiv thawj zaug
Xaiv C44300 thaum ib puag ncig pom cov yam ntxwv no:
Tsawg- dej ntws los yog dej tsis tu ncua (cov thawv ntim dej condenser, ib nrab ntim cov tshuab)
Brackish los yog dej qias neeg nrog cov ntsiab lus chloride / sulfide siab
Kev kub siab (feem ntau yog 40-80℃/ 104-176℃F) hauv kev sib pauv cua sov
Nyob ntawm chav dej condensate lossis hloov pauv ntub / qhuav
Tsawg- cov pa oxygen uas ua rau kom dezincification
Xaiv C46400 thaum ib puag ncig pom cov yam ntxwv no:
Kev ntws tawm dawb, dej hiav txwv aerated (nkoj hulls, propellers, los ntawm -puab fittings)
Ntxuav, tsis muaj kuab paug seawater nrog ib txwm marine biological ua
Ambient rau nruab nrab kub (0-40℃/ 32-104℃F)
Siab - dej ntws ceev (tswj impellers, valve Cheebtsam)
Kev saib xyuas tsis tu ncua thiab kev tshuaj ntsuam xyuas yog muaj
Daim ntawv thov -Txoj Kev Xaiv Cov Cai
Kev siv cua sov hloov
Rau condensers, tshav kub exchangers, thiab cua txias tshuab:
C44300 yog qhov yuav tsum tau ua thaum:
Tube phab ntsa thickness tsawg dua 1.0 hli (0.04 nti)
Dej tshaj tawm yog qis dua 1.5 m / s (5 ft / s)
Lub kaw lus tau ntsib kev kaw ntau zaus lossis cov xwm txheej standby
Hloov tus nqi / downtime yog siab dua li cov khoom siv tus nqi hwm
C46400 yuav raug txiav txim siab thaum:
Tube phab ntsa thickness tshaj 2.0 hli (0.08 nti)
Dej tshaj tawm tsis tu ncua tshaj 2.5 m / s (8 ft / s)
Qhov system ua haujlwm tsis tu ncua nrog kev kaw tsawg kawg nkaus
Tus nqi pib yog qhov kev txwv tseem ceeb thiab kev cia siab rau lub neej ua haujlwm yog nruab nrab (5-10 xyoo)
Cov yam ntxwv thiab cov khoom siv tshuab
Rau shafts, propellers, li qub, thiab marine hardware:
C46400 zoo dua thaum:
Cheebtsam kev paub txog torsional lossis dabtsi yog khoov kev ntxhov siab (lub kiv cua shafts, rudder stocks)
Yuav tsum muaj kev cuam tshuam txog kev cuam tshuam (cov khoom siv hauv hiav txwv raug cuam tshuam rau qhov chaw nres nkoj)
Kev hnav tsis kam yog qhov tseem ceeb (cov kabmob nto, thaj chaw bushing)
Machining los yog forging yog yuav tsum tau rau cov khoom fabrication
Qhov hnyav - rau - lub zog piv yog qhov xav tau
C44300 yuav tsum tau txiav txim siab tsuas yog thaum:
Cheebtsam yog nyob rau hauv mus tas li kev sib cuag nrog stagnant seawater
Galvanic compatibility nrog C44300 tubing tshuab yuav tsum
Daim ntawv thov suav nrog nyias- cov khoom siv phab ntsa hauv qhov chaw corrosive
