UNS C44300 Admiralty Brass Tube PDF
C44300 tooj liab tubing yog dab tsi?
Admiralty Brass yog ib qho kev ua haujlwm siab - tooj dag alloyed nrog tin (0.9-1.2%) thiab kab kawm xws li arsenic thiab hlau. Nws cov chemistry meej tiv thaiv zinc leaching hauv dej hiav txwv thiab cov tshuaj hnyav, ua rau nws zoo tagnrho rau cov raj, fittings, thiab cov khoom siv hauv cov khoom siv hluav taws xob, cov condensers, twj, thiab li qub. Cov kws tsim khoom txaus siab rau nws qhov sib npaug ntawm lub zog, kev coj ua, thiab tshuab- muaj peev xwm, thaum cov neeg yuav khoom muaj txiaj ntsig rau nws cov pov thawj kev txuag nyiaj ntau dua li cov hlau sib tw.
Admiralty Brass (C44300) tau teeb tsa tus qauv rau tooj liab-zinc alloys hauv kev xav tau marine, kev lag luam, thiab kev siv cov txheej txheem.
Tsim nyob rau hauv lub xyoo pua 19th kom tau raws li Royal Navy qhov kev xav tau rau lub dezincification-cov hlau tsis muaj zog, tam sim no yog cov khoom siv rau cov kws tsim khoom thiab cov kws tshaj lij kev muag khoom uas xav tau kev ntseeg siab, ntev - cov khoom siv tau ntev. Cov dej hiav txwv no-qib, dezincification- cov kav dej tooj dag tiv taus kom ntseeg tau tias muaj kev ntseeg siab txawm tias cov dej ntsev hnyav tshaj plaws.

Kev Pabcuam Kev Cai:CNC machining, dabtsi yog khoov, brazing, thiab kawg sib dhos txhawb nqa
Piv txwv li kev siv
Piv txwv li 1: thawv ntim condenser raj
Ib lub nkoj 12,000 TEU tau ntsib cov raj xa dej tsis zoo hauv tsib xyoos. Tube bundles ib ASTM B111 raug ntsia. Tom qab kev teeb tsa, tsis muaj lub raj xau tau tshwm sim ntau dua yim xyoo, txo cov nqi khoom qhuav los ntawm $ 300,000 ib xyoos ib zaug.
Piv txwv 2: Middle East cheeb tsam cua txias cog
Ib qho 80 MW cog tau ntsib cov raj fouling thiab kaw tom qab peb xyoos. Admiralty Brass plate-and-frame exchanger plates tau retrofitted, xa ib tug 12% efficiency boost thiab txiav unplanned shutdowns los ntawm rau mus rau ib xyoo, projecting ib tug 30% txo nyob rau hauv tag nrho cov nqi ntawm cov tswv cuab tshaj 15 xyoo.
